Although the mouse is not the most robust part in a computer, if it has some malfunction, it would seriously affect your computer working well. Usually if a mouse is working irregularly, it would have problems like that the pointer is movable on the screen but later it freezes up, or sometimes the pointer may jump on the screen erratically, etc. If such failure happens, how can you repair it?

First of all, you need to clean the mouse pad. Because the pad may have a lot of dirt or grease as you drag and drop your mouse on it heaps of times.

Then if the first check can not work, go to the second step. But before you do this, you have to know what kind of mouse you are using.

If it is a ball mouse, you need to take the ball apart from your mouse and clear up all the obstruction like dust and dirt built-up on the ball and inside the mouse. With certain computer knowledge you even can disassemble the whole mouse and completely clean it.

If it is an optical mouse, you have to check its bottom to see if there is something like a piece of tape there. Beside, test this mouse on another surface like a sheet of paper to see if it can work regularly.

If the mouse still fails to work, try to reinstall its driver, or download some driver tools like Driver Checker to help you find out the most suitable mouse driver.

Additionally, the opening or closing of a process or the high CPU usage also can make a bad impact on your mouse working. However, the failure also could have been a broken mouse, or that it has been used too many times and should be obsoleted.

Perform a FREE SCAN to see what problems your mouse driver has and how to fix them quickly and easily!

Bitcoin was launched as a private initiative in 2009. Unlike traditional arrangements, such as the Euro, Sterling and Dollar, it is not controlled by a central monetary authority. Instead, it is underpinned by a peer-to-peer network of its users' computers. This is similar to how Skype, a video chat service, operates.

The basic unit of value is the bitcoin . However each bitcoin can be subdivided into satoshies. One satoshi is equal to one hundred millionth of a bitcoin (ie, a bitcoin divided into eight decimal places).

Bitcoins and satoshies can be transferred from one internet user to another in order to pay for goods or services at virtually zero cost. This allows you to make international transfers without having to mess around with exchange rates and onerous bank charges. Bitcoins can be bought and sold for traditional cash at special exchanges.

Bitcoin wallets

In order to use Bitcoin, you need a wallet , a special piece of software in which you store, send and receive bitcoins. There are three kinds of wallets, software wallets, mobile wallets and web wallets.

Software wallets are installed on your computer and they give you full control over your wallet. Mobile wallets are installed in your smartphone or tablet and allow you to use Bitcoin for daily transactions in shops and supermarkets by scanning a quick response (QR) code. Web wallets are located on the World Wide Web, ie they are a form of cloud storage.

Payments using bitcoins are super easy. They can be made from wallets on your computer or smartphone just by entering the receiver's address, the amount and then pressing send. Smartphones can also obtain a receiver's address by scanning a QR code or bringing two phones that contain near-field-communication (NFC) technology, a form of radio communication, close to each other.

Receiving payments is just as easy … all you have to do is give the payer your bitcoin address.

Protecting your wallet

A bitcoin wallet is like a wallet full of cash. To reduce the risk of loss, you should keep only small amounts of bitcoins in your computer or smartphone and keep the bulk of your bitcoins in a safer environment, such as an offline wallet. Provided your wallet has been encrypted, an offline back-up will allow you to recover your wallet, should your computer or smartphone be stolen.

Encrypting your wallet allows you to set a password that must be input before funds can be withdrawn. However, recovering a bitcoin password is impossible if it is lost. That is why you need to be absolutely sure you can remember your password. If the value of your bitcoins is significant, you could store the password in a bank vault or where you store important papers.

In order to be as secure as possible, you should store off-line back-ups in multiple locations using various media such as USB flash drives and CDs.

Because bitcoin runs on software you download to your computer (PC or laptop) or smartphone, you need to update this software regularly in order to keep your wallets and transactions safe.

Advantages of bitcoins

Bitcoins have several significant advantages:

1-you can send and receive limitless amounts of money instantly at any time to and from anywhere in the world.

2-processing does not cost any fees or only very small fees.

3-bitcoin transactions are irreversible, which protects sellers from the fraudulent charges that are increasingly common with credit cards.

4-payments are made without personal information being upgraded, which provides strong protection against identity theft.

5-the receipt and payment process is completely neutral, transparent and predictable.

Disadvantages of bitcoins

However, using bitcoins has several disadvantages:

1-they are not yet accepted universally and then can not be used everywhere.

2-their value is volatile because the number of bitcoins in circulation is quite small so relatively small transactions can affect their price significantly.

Should you use bitcoins?

The short answer is NO or, at least, not in a major way yet.

Bitcoins are fungible assets with durability, portability, divisibility and scarcity, ie they have all the characteristics of conventional money (Euros, Dollars, Pounds etc). They have value so they can be changed for other currencies at exchanges.

Therein lies the danger. There are times when the value of the bitcoin can fluctuate broadly, by 50% in one day. So, as a store of value, they are not for the faint-hearted. In other words, you should not have more money than you can afford to lose in the form of bitcoins.

However a wallet with small amounts of bitcoin in it could have been used for minor day-to-day transactions which would help familiarize you with internet treaties. As the amount of bitcoins in circulation increases, their value viz-a-viz other treaties should stabilize and you can start using them for larger transactions.

BEST:

Wargames (1983): The top of the list! What can you say about this movie other than marvel at it's greatness. What's that you say? You're not convinced it's the best … well then your probably under 40. For those of us that were around during that time, the accuracy of the equipment and methods used were 100% spot on. I'll forgive a little poetic license with the voicebox (even though they did exist at a more primitive level), but if you had to read what was on the screen the movie would get tiresome real fast. It added to the creepiness of the emotionally void WOPR when the voice says, "To win the game." The voice, BTW, was provided by the director who recorded the lines by speaking them in reverse, then played back in the opposite reverse direction … ??? You know what I mean. It completely represented the aura of the time. If you buy the DVD that has the director's comments, you'll find that they purposely used a hodgepodge of older computer equipment so it would accurately represent what a teenager would be able to afford or scrounge up during that time. Incredible accuracy, especially the part showing how to jack a pay telephone with a soda can pull tab. What's a pull tab? Go away kid, ya bother me!

Tron (1982): Even though this film came out in the 80's, it feels like a late 70's film. I do not know why. Basically it's about a hacker that is transported into the digital universe inside a computer, and must survive combat as a cyber gladiator in order to stop the villainous Master Control. It wanes a little in places, but make no mistake this was a groundbreaking adventure at the time. The graphics, while now, were extremely cutting edge at the time and wowed movie audiences lucky enough to see it on the big screen.

Pirates of Silicon Valley (1999): Not so much a hacking film as a corporate espionage film … involving computer companies. Fantastic tale from start to finish. My only gripe is that it does leave out some key information. For instance, the only reason Bill Gates got in to see the higher up's at IBM was that his mother served on the same board of directors for a charity that the IBM chairman served on. She got the wheels rolling on the meeting. It also makes Bill Gates out to be some rebellious drop out who risked everything to start his company. Truth is, Bill was a multi millionaire by the time he went to college thanks to a generous trust fund from his grandparents and parents, who were also very wealthy. So was Paul Allen, who knew Bill from their grade school days at one the most exclusive and expensive private schools in Seattle. They were not hurting for anything … unlike Jobs and Wozniak. Still the historical bend of this movie makes it one of the best biopic films for computer nostalgia nerds.

WORST:

Sneakers (1992): Some of the hacking was OK, but the social commentary peppered through by Robert Redford made this film unwatchable. If you want to blame Republicans for everything, watch a Michael Moore movie. If you want to make a hacking movie, leave your left wing garbage out and just make a damn hacking film. Is that too too to ask there, Bobby? The story revolves around two college buddies who take different paths in life. One becomes an "ethical" hacker, and the other … well, he is not quite so noble, although rich. The underlying message is that capitalist greed is bad but being broke, running from the FBI, and working in a run down, abandoned warehouse is morally superior. Some great plot twists and comic scenes ruined by over the top political grandstanding make this a movie I would only watch if it were free … and beer was free.

The Net (1995): Ugh. The only saving grace of this movie is Sandra Bullock. Technology at that time was emerging at a great pace. This thing called 'Internet' was finally taking off and the filmmakers and writers took a lot of poetic justice to portray what computers might be able to do in the 2 months between shooting the movie and releasing it. It had it's moments but the whininess of Bullock and the whole separation of the security software hack made it almost unwatchable. A good MST3K candidate.

Swordfish (2001): This movie's tagline should tell you just how unrealistic the hacking is: "Log on. Hack in. Go anywhere." Steal everything. Yeah, it's that easy. If you watch the movie, you'll realize that's exactly what the filmmakers believe . John Travolta is a villain who's grand scheme is to steal billions from the US government through yes, you guessed it … hacking. The entire premise of the plot is that in the vast, computerized world of modern finance, $ 9.5 billion could slip through the cracks so that a clever hacker could, with hacking, transfer it to his own account unnoticed. Heck, I could use a new car … I'm gonna hack a few grand right now using my Hollywood generated CGI screens with 3d hacking tools where the mouse moves even though your hands are busy typing! It may have fooled the unwashed masses, but we know better.

Whenever you are using the Linux, in whatever distribution you like the most, you have a Home folder. This is an extremely important folder for everything that you do on that machine. Due to the way that Linux segments it's file system, it's important to keep track of what is in this home folder. Although it sounds like basic file management and as such can sound boring or repetitive, when things go wrong being aware of where you have saved what, can make all the difference.

First of all the home folder is much like your "My Documents" that you have in Windows. Your basic files that can include pictures, music, video, documents, and downloads will be saved into this folder. For each user on the computer, you will get your own folder that holds your own personal documents. This is important as this segmentation provides you with privacy, but more importantly, your own organizational system.

There is another part of the home folder that many do not realize. There are actually many folders within this folder that are hidden. This means that the folder starts with a period followed by the name. If you are using Gnome, hit Control + H to see these hidden items. What these are is your settings for various applications on the computer. If you have a certain application with saved states, customized choices, or whatever, it will remain this way because there are files in your hidden folder for that application that keeps those settings.

Backing up your home folder is very important because this is what you really need if you have to reinstall the system or move your settings to a new computer. When you backup, make sure that you backup all these hidden folders as well. Do not make the mistake and forget about the hidden ones else you will lose all your customized options.

Some advanced Linux users will actually mount the home folder as a separate partition on their drive. Then when they have multiple versions of Linux or other operating systems, they can always rely on that home folder and be writing and reading from it at all times.

Have you ever wondered why your notebook computer or desktop runs slower and slower? Does it keep freezing and reporting errors? If you are fed up with this and want to speed up a slow PC there is a solution.

A slow desktop computer is really annoying because it can stop you getting anything done. What's significant is if this problem is left it can crash your computer.

In 9 out of 10 occasions the problem is a corrupted registry. The computer registry is hidden deep within your computer and its job is to store info about everything on your PC, both hardware and software.

Over time the computer registry becomes filled with invalid entries and becomes corrupt.The computer registry may well also turn out to become corrupted due to virus infections or adware and spyware. You can locate many anti-virus and anti-spyware programs around the net which will clear up and speed up a slow PC.

Here are some other tips to help you speed up your PC.

# 1 Free up some RAM. When the RAM memory just is not sufficient, your desktop will not be in a position to run every single task at hand. To obtain more free memory clean up outdated or unused applications which are saved inside your hard drive.

Go to the control panel, then add or remove programs and remove which software packages which you simply no longer use. Once you have done this get rid of them from the recycle bin.

# 2 Run the windows disk defragmenter. If you've not done this before then it's possible that the disk is fragmented and program files are scattered all over the place.

# 3 Do not leave the computer on 24 hours a day. Restarting it once every few hours will close programs that have not been closed properly. Some programs keep using memory, even though they appear to have closed and the solution for this is to restart your computer.

It shows this when your programs will take a long time to run and start which could reduce the general speed of your computer.

to run this go to the windows start menu. Then to accessories, then system tools and finally the disk defragmenter. Run this and speed up a slow PC quickly.

Despite the fact that the above may well be very beneficial, the best answer by far is to use a registry cleaner. This software will scan your computer, will locate and fix each of the errors speed up a slow PC and make it operate like new again.

When you buy a new PC, you're very satisfied with its speed and performance. Well, not for long. Installing new applications, creating and deleting files and with other daily use of software, your computer gets sluggish, files get corrupt and most annoying it hangs a lot.

One such PC annoyance is the apparently never-ending boot up time. A faster PC naturally requires more memories – both physical (RAM) and virtual (reserved hard disk space). But that's not the only issue you need to address for making a PC run faster. Buying a larger RAM may boost your PC's speed but you have more important and obviously less expensive methods of making your PC speedier.

Here are few important tips you need to know for re-gaining the speed:

De-fragment regularly

Over a period, the files and folders in your hard drive get fragmented. This reduces the efficiency and speed in accessing the files and loading the applications. As a routine maintenance practice, you should de-fragment the hard disk. You may use the default Windows Disk Defragmenter or any other de-fragmentation software available on the internet.

Clean up start-up programs

When you install different applications, some of them load in the system memory as soon as your PC boots. Other than some security related (like anti-virus or firewall) software, you do not really need them to load and take away a large chunk of system memory. Consider removing them either from the start-up folder, from the application's settings or from the Startup tab of the System Configuration Utility (Start> Run> Type msconfig> OK).

Un-clutter your desktop

Many of us like desktop wallpapers, themes, animated icons on our desktop. They may be decorative but they take away a good amount of system memories. If your PC is annoying sluggish, consider using a cleaner desktop.

Clean Registry

Registry is what we can call as the Window's black-box. Corrupt registry or invalid registry entries bring the performance down and severely slows down the PC. Consider using a registry cleaning software regularly to keep your PC in good shape.

Get rid of unnecessary fonts

When Windows boot up, it loads the installed fonts. Too many fonts will there before reduce the speed of boot up. Installing newer fonts is somewhat tempting but considering the speed you need, you should reconsider their actual requirement. Many of us install a font and never use it again. Uninstalling fonts will improve your PC's speed to a great extent.

Speed ​​is a universal need for all PC users. If you follow the above tips, chances are, your Windows will load much faster and your PC performance will see a positive change.

Microsoft Windows 7 is the latest version of Microsoft Windows operating system. Compared to its predecessor Windows XP and Vista, Windows 7 is more powerful and more secure. Unlike Windows XP, Windows 7 adopted a new password protection system that we can not use the hidden administrator account by default. The problem is that when Windows 7 administrator password lost, we can no longer recover our lost password by using the hidden administrator account. Therefore, how to recover the Windows 7 Admin password if we lost or forgot it?

Do not worry, here are two methods for Windows 7 administrator password recovery:

Method one: Use another Windows 7 administrator account

If you had created more than one administrator account on your Windows 7 computer and you can remember the others admin password, you are lucky. In such a case, you can change one of the administrator accounts' password if you login with another administrator account. What you need to do is just following these 3 easy steps:

Step 1: Click Start -> Control Panel -> Add or remove user accounts

Step 2: Choose the locked administrator account.

Step 3: Click Change the password or Remove the password. And then you can change or remove the lost or forgotten password.

Please note: If you select this method, the locked Windows 7 administrator account will lose all EFS-encrypted files, personal certificates, and stored passwords for Web sites or network resources.

However, if the locked account is the unique administrator account on your Windows 7 computer, you can try the method below.

Method two: Use third party Windows password recovery software

There is plenty of software which is used to recover Windows password available online. You can choose one of them to create a Windows password recovery disk and use the disk to recover Win 7 Admin password. Then you can follow these 4 easy steps:

Step 1: Download the software and install it on another computer which has a CD / DVD writer.

Step 2: Run the software and burn the ISO image file into a blank CD / DVD.

Step 3: Recover Windows 7 administrator Password with near burned password recovery disk.

Step 4: Reboot your locked computer without a password required.

Now you can regain access to your Windows 7 operating system and create a new administrator password. The best thing of using this method is that you should not lose any data on your computer. Furthermore, if you can not find a computer which has a CD / DVD writer or the locked computer have no CD-ROM, you can burn the ISO image file into a USB flash drive and use the USB flash drive to recover your Windows 7 administrator password.

Try these two methods the next time you lose or forget your Windows 7 administrator password, which you do not need to reinstall Windows system for getting back to Windows by removing lost or forgotten password.

Good writers are wordsmiths. Like the building blocks, they have acquainted the skills to carefully choose words that will convey specific meanings to their readers across the globe.

Acquiring the skills to write copies that will add values ​​to your readers take time and lots of efforts. It is not a tea party.

You have to leave your comfort zone, read anything and everything under the sun, sleep less at night, stay on your computer till thy kingdom come, browse the net to get specific information, etc.

But, above all, you have to write, write and write. Reading is just 1%, while practice is 99%. There is no magic in crafting good copies. It is more of practice than talking.

But, when you write good copies, you have to let the world know.

In this 21st century, computer and the Internet have reduced our world to a global family. It used to be called a global village. Off course you know this.

So, how do you market your writing skills to the entire world? Good question. The internet is a global library and a potent and dynamic market place for everyone.

Therefore, whatever product or service you render to humanity can find ready buyers online and offline.

Websites, blogs, the social media, emails, forums, directories, online advertising agencies, etc, are good platforms for announcing yourself.

But, let me be realistic with you, my brother, my sister. Like every effort under the sun, there is no quick-fix approach to marketing yourself first and typically making money online.

It is work first before payment. When you go to some restaurants in Nigeria and abroad, you order for your meals before payment. Yes, some will demand money before the meals.

But, in online writing business, you have to work, research, read, browse and request for specific information from Google, or any of the search engines.

For days, weeks, months or even years, you must continue to announce your presence, give out almost all your products, free and then wait patiently for the conversions to start rolling in.

But, the truth is that in a world of the good, the bad and the ugly, trust online and offline is a big deal. You have got to earn the trust of your readers.

As at 2015, online reports quoted the international telecommunication union as estimating that in a world of about 7 billion people, 3.2 billion of them use the internet.

About 2 billion people from developing and 89 million from least developed countries also use the internet.

These figures show a huge market for writers. But, before I sign off, please remember the trust angle I told you earlier. God bless humanity.

Many people hate working for a boss and aspire to own their own business. They value not only the potential for monetary success but the independence. But one issue that comes up is that the amount of choices are overwhelming. There are so many types of businesses to start that wannabe entrepreneurs don’t know where to start. One popular idea is an internet cafe. As with any business, there are advantages and disadvantages to starting one. Here are some things to think about before making the first move.

The advantages of an internet cafe are numerous. Probably the biggest one is the low startup cost. The biggest limiting factor for aspiring entrepreneurs is the lack of capital. Internet cafes are relatively inexpensive to start. Computers are cheap. The labor does not need to be skilled. Furnishings do not have to be expensive. This is in great contrast to a restaurant, which usually requires special equipment, extensive refurbishing and a larger area and amount of employees. A franchised restaurant would also require paying the franchise fee.

Second, there are many ancillary revenue opportunities. The most obvious one is selling internet time. But you can also target gamers, by buying some high-end computers and charging more. You can also sell food and drinks (coffee is a popular option) and computer repair services. These multiple streams of income will help stabilize your revenue base.

There are several disadvantages to starting an internet cafe. Since the startup costs are so low, the market is extremely competitive. Many people consider an internet cafe to be a commodity service and will go with a new store if it is cheaper or if the connection is faster.

3D games are increasingly becoming popular. This has been made possible by changes in the software development technology. There has been a gradual shift from the 2D to the 3D technology. The 2D technology emphasizes more on the graphic's width and height while the 3D technology emphasizes on its depth, in addition to the width and height. The depth helps to create an illusion that is critical in producing images that are more realistic.

Importance of 3D images

3D images are important in the film and cartoon industry. The technology is relied upon heavily to design 3-dimensional computer games. Some of the software is recommended for designing living animals while other software are ideal for creating objects like parks, buildings and cars. This makes it possible for films to capture scenes where vehicles are blasted while the occupants are present. In real life, such a scene can not be captured on camera. The software to help develop the scene often captures images of the real people.

The 3D animation software is important in the filming industry. Therefore, it is the responsibility of the graphic designer to find the right software for the best results. There are commercial 3D software and the open source 3D software. The commercial software can be valued anywhere between $ 1,000 and $ 2,000.

If you have a limited budget, you can consider the open source 3D software available online. However, the free programs offer limited features. The open source 3D software can be downloaded from the internet. Alternately, you can receive the software through your address when you pay a small amount of money to cater for the shipping charges. In case you are new in the industry, you can consider trying out free software before launching out to purchase the commercial software. Some of the free 3D software available for graphic designers include Free Cad 8.0, touch sampler, Cyberdelia, Special effect 3.2, Serif 3D plus and Gmax.

Popular 3D animation software

Maya is considered one of the best 3D animation software among professional graphic designers. This software can be purchased easily online using a Visa or Master card. The Maya can be supported by several operating systems including Linux, Microsoft windows and Mac OS X. The software was initially designed by the Alias ​​Systems Corporation. Currently, it is being developed by Autodesk Inc. The Autodesk Maya creates 3 dimensional figures that can be used in the filming industry, video games and cartoons.

Google has announced the launch of Chromebook. Chromebooks are laptop computers that use its own operating system, rather than that of Microsoft. Google has promised that the Chromebooks will be available in market from June, 2011.

The machines for Google Chromebooks will be made by Acer and Samsung. Both of these manufactures previously made machines for Microsoft's software.

The launch of Chromebooks is Google's move onto Microsoft's home turf of PC operating systems and the Office suite software. Till today, Google did not have a direct competition with Microsoft as it only focused on areas like search and webmail – place where Microsoft is not very strong.

The laptops will save data on Google's "cloud" online services, and have almost no capacity to store information. Instead of storing software and files on the PCs, these computers will take the users directly to the internet.

According to the executives of Google, their Chromebooks save user's time by shifting day to day functions of installing software, checking viruses, creating backups etc. to the web

At the IO conference in San Francisco, Sergey Brin, Co-founder, said "The complexity of managing your computer is torturing users. yourself. "

In the past 15 years, PC sales have grown steadily. Even during the times of recession, there was not much impact on the sales of computers. Microsoft mainly serves business with their technology. Google plans to target business and corporations as well by providing them with much safer data storage in the cloud, instead of on the PC that could be lost or stolen. Google will offer Chromebooks to business at a price of $ 28 a month.

The Chromebooks will be available in the US on Amazon.com and Best Buy's online store from 15 June. Chrome operating system will be totally free, just like Google's android mobile operating system.

With about 90% of the world share, Google is the most dominant provider of search adverts on the internet and the intent of Chromebooks is to encourage people to use more internet, which would result in more clicks and view of advertisements.

On Tuesday Google launched an online music locker services in the US, which allows users to store and listen their songs wherever they are. The Chrome browser already has 160m users all over the world and Google expects this number to grow along with the number of Chromebook users.

One of the worst threats to computer users today is Spyware, be it a virus, Trojan or a stealth downloader. These nasty programs have been associated with slowing computer's performance and security issues like identity theft. In this article we will discuss them more.

Do to the fact that all our computers are connected together via the Internet, if one person gets Spyware then all of that person's friends end up with it too do to email, messenger programs like MSN and links. Many Spyware can use an user's email address book to automatically send its self to all their friends. It does not take long to spread across the Internet in record speed.

Hackers used to go after exploits in the Microsoft operating system, that forced Microsoft to keep patching and updating their software to close the holes. That has made the malicious coders to go after other software programs that we use on a daily basis like Adobe Flash, Java, and certain web browsers. Since almost every computer has one or more of these programs they are more vulnerable than ever.

You may have searched online for Trojan removal because your computer is not working properly or having strange things like like pop up windows. Here are some symptoms:

• Slow to boot
• Registry errors
• Windows updates failed
• Firewall turned off
• Corrupted files
• Registry errors

Computers or computers are wide open to trojan and security risks from all sorts of directions but it's too bad the time and resources needed to maintain and secure a computer or whole network is time consuming to a large number of home and business users so the problem is often not deal with.

For many people who are not experienced in how to keep everything up to date or secure, having an online remote tech log in and get it done is a great alternative to taking your computer in or having an IT tech come to you.

Viruses are not going to be simply problems that prevent you from using your computer, they can bring about lots of other issues at the same time so take them seriously. Increasingly cyber criminals are using trojans to get into computer systems and stealing personal data which is later used for identity theft, so if you believe that something bad happening on your system has it checked by a certified computer technician.

The best way to remove all the junk and get your computer running like it should yourself is to download Malwarebytes or Superantispyware, either of these will do the job. If you computer is too badly infected and being blocked from installing / running / or updating these programs then Online Computer Repair will help you get it done.

Animation is a very interesting career. There are several skilled options for computer animators. Animators are artists in a way. They create cartoons which are a favorite of not only children but also of many elders. These cartoons are created for movies and films.

The job of animators is to create cartoons. But the field is not restricted to cartoons only. Animators also make computer graphics for several projects. These graphics combine video games, website graphics and also graphics for advertisements on the net.

Most of the computer animators are employed in production companies. Some of them also find employment with advertisers, in web design firms, in video game companies or in animation firms. Animators can also go for freelancing. Freelancing may be lucrative for web animators.

The Education Associated With This Field

At the grassroots level, an animator needs to possess a bachelor's degree in either media or in fine arts. There are several schools teaching animation. Not only computer animation, the technologies associated with it are also taught in these schools. In order to be successful, an animator needs to have a strong portfolio. Above all, a person must be adept at his work in order to prosper.

The Different Types Of Animations

VIDEO GAME ANIMATION: this industry is progressing with time. No blockages can be noticed in its way. Almost all the games that are there need several animators to help them function. Sometimes motion capture is used to curve done animation. But there still is a lot of work that can be done only by an animator. You can think of the several elements that are included in a feature film.

INTERNET: as you switch on your net, you can see animated advertisements floating all around. In most of the sites that you visit, you will see several animation designs flashing around, making the page very interesting and attractive. The internet is widening at a very fast pace. New websites are coming up at a very fast rate. So the demand for animation on the net is also increasing.

The Salary Factor

Animators and multimedia artists earn a salary of $ 44, 000 per year. At some places the salary is as high as $ 60, 000. This field is also like several other fields. The salary varies with the location of employment.

This is an industry where competition is very tough. There are several talented animators working, constantly chasing to create computer graphics. You need to excel in order to be successful in this industry where there is cut throat competition.

Computers today are used in every part of life. They are used for communication, work, play and even to buy food. Therefore, when you lose a computer or even just a file from your computer, it is like losing your best friend. You can not back up or replace a best friend, but you can backup files, or your entire computer if desired.

Several back up methods exist. Some computers will automatically back themselves up; you just need to find the folder where the back up is stored. If your computer does not have this function, or you are not sure if the function exists or is working, manually back up your files. For example, after creating an important Microsoft Word document, save it at least twice in at least two different locations.

If however, you lose your own hard drive, it will not matter how many times you have saved the same document. To avoid this dilemma, save your files on something other than the computer's hard drive. Floppy disks are not commonly used, but they will work for small files. Be ware that floppy disks can be unreliable and often crash just as your computer did.

USB Drives are becoming more popular as a back up tool. A USB drive is a small device that holds large amounts of information. It works like a floppy disk in that you can place files, delete files or move files around within the USB. All recent computers have USB ports that should be able to read any USB device.

CD ROMs are also a popular way to back up your files. A CD ROM looks just like a music CD you would buy in a store, but can hold up to 700 MB of information. This allows for large files or a large amount of small files to be stored on this disk. Once you put information onto a CD ROM, you can not add files or change the files on the disk. This can be one way of ensuring nobody else tampers with your work, but can also be frustrating when you would like to back up a new version of your work. In this case, a CD RW disk may suit you better. RW stands for re writable disk. On this kind of disk you can add, delete and rewrite files until the disk is full. When using the rewrite option, be sure you do not accidently rewrite something you wanted to keep the back up of.

Both CD options can be done on most home computers. You will need a CD (possibly two in case the first one ends up as practice!), And a CD burner. Almost all computers sold today, or sold recently, are equipped with a basic CD burner and burning software that is generally simple to use. If your computer is not equipped with these devices, you may purchase a basic CD burner and software for a reliably inexpensive price. Once you have created your back up CD, take care to keep it in a cool dry place where it will be safe from damage.

In early 08 laptop computers appeared to dominate the market for a portable computer, until they faced a new competitor: the netbook. A smaller, more compact, version of the laptop basically. The main difference between laptops and netbooks is size. A laptop is usually the larger and less portable version of the two, sometimes may require to be plugged in for power (which is a horrible disadvantage) but, of course, laptops feature more power, and in turn, you can do a lot more stuff with them. From hardcore gaming, to website design, to small stuff like browsing and writing an essay in word. Depending on the specs in the laptop you have you can usually do all of these activities. The netbook, is small and more compact version of the laptop BUT features less power unfortunately. In turn, you can not do as much with them, they are more for the "college student" someone who needs something for the basic functions of a computer. Such as internet browsing, uploading photos, and listening to music. There are a couple of other types of products which I believe are in the "portable computer" category. You have of course laptops and netbooks but there is also notebooks and ultra-mobile PCs. But we will be sticking to the basics in this article, laptops and netbooks.

What's the difference you ask? Are the terms well defined, are they interchangeable? Well that really depends on who you ask, I mean to someone a puddle might be a pond. But in this occasion I believe a netbook is a netbook and laptop is a laptop!

But anyway this brings us back to the main topic, the difference between laptops and netbooks. Like I said, the main one is size which most people use to recognize each. In general laptop computers will be larger than netbooks. In weight and size, laptops are usually larger. Usually laptops will be the more expensive and powerful out of the group, netbooks are used more as "side computers" not really used as main computers for the whole household. I would recommend having a powerful desktop PC for the whole household, and maybe everyone has their own personal netbook for anything they want to do on the move. As the price on netbook is usually very affordable, you can supply the whole family with one. I believe you can get a quality netbook for around $ 200- $ 300.

Developed by the Roblox Corporation, and compatible with Microsoft Windows, Roblox is a downloadable game that requires 1.8 Ghz processor and 512 MB of RAM. It is an online game that requires Internet connection and is a multiplayer game, too, so your child will be able to communicate and interact with other players. When your child downloads the game he or she will be able to customize the character that they want to play as by selecting a variety of things from the catalog. In this catalog, there are many things that are created by the users of the game, additional types of things that are already present, too, made by the Roblox company, and your child will have the ability to choose things such as clothing for their character that is personal and representative of your child's preference and style.

Also your child can choose models for their characters that best represent them and images, different kinds of heads and faces are available, as well, so your child will be able to create a sort of avatar that is best representative of who they are and they will feel as they are really playing the game. They can choose gear, too, from the catalog, that they will use in the game, as well as various other sets that can help them when they start playing. If your child subscribes to Roblox and becomes a member, they can also have arms, legs, and torsos that are made and designed by the company and that will distinguish their characters from non members who still have access to all other features of the package. If your child is very proud of his or her creation, then he or she can take it to the Roblox catalog and if it is liked by other characters and players, then it can become a part of the catalog as well and other people can choose it in the future.

Roblox offers over eight million types of games that your child can participate in. Your child will get to choose a genre for the place in which they will play the game and they can choose pieces to build from that were already made or can create custom worlds where they can play using block style elements that they create worlds from that are often maze like. Usually a player can make about one hundred different locations using blocks for building that are given to them in an unlimited amount and supply. Usually while the player is building, they can use Lua scripting, which allows them to track their building process by creating a button and doing other things that enhance the building experience.

In fact, the builder can even use the GUIs to help them build, and with these GUIS, that were once only used by administrators, players can make a control panel for a game with buttons and options that allow them to do certain things. There is a huge sense of custom built and self made fun in Roblox as the places are built by the players and the competitive nature of the game rises from the fact that a lot of it was self made, down to the buttons and the panels for control options.

Usually players also play for money currencies, as they earn it depending on things they do and have the ability to trade Robux and Tickets when they need to buy things. When people visit the places that they have built, they are awarded this currency and every time they log into the game, they also get paid. Also, if members want to sell their own creations, too, they may earn money that way, as well.

Computers are almost becoming an integral part of our life. The ever-growing number of computer users certainly requires competent people for repairing these machines. This has already led to a spurt of service providers for the repairs of PCs. Consequently, one comes across many people who claim to be qualified enough to undertake computer repairs.

Unfortunately, unlike plumbing and HVAC repairs, computer repair happens to be among those services which are not yet regulated by any government agency, and thus don’t need any official licensing. A lot of people depend on their computers for doing important tasks to keep their business running, and simply replacing the machine isn’t a viable proposition. It becomes imperative for you to be extra careful when looking for someone to repair your system. Here are a few questions you should ask a prospective computer technician to confirm that he is qualified to undertake the job:

Do you possess any certificates?

Though there is no official stipulation for working as computer repair technician, there are certain customary certifications which a proficient technician should possess. A+ is the most essential certification. A person qualified for this certification is expected to have a broad knowledge about working with software and hardware as applicable for computers. Likewise, if you want your printer, server or network to be repaired, make sure that the service provider is trained in that particular field.

How long is your practical experience?

Practical experience is the most important for servicing any equipment, and computer servicing is no exception. The greater the experience in servicing computers, the better will it be for you. Find a technician with a minimum experience of five years, though ten would be ideal.

Are you employed by a company or is this just a one man show?

You should know the background of this technician. At times, technicians employed by large companies may fail to deliver the required level of service. One reason could be the lack of experience. Moreover, such technicians do not bear any personal responsibility for the efficient working of your computer. On the other hand, a technician owning a small computer repair business will be keen to do a perfect job, in anticipation of getting repeat business and good references from you.

Are you covered by liability insurance?

In case the technician doesn’t have a liability insurance, compensation for any damage done to you, your computer or any of your properties may have to be settled through court, or you may need to pay for technician’s blunders from your pocket.

What is the guarantee or warranty of your services?

What if the technician isn’t able to fix the issue in totality or the problem reappears soon after it has been rectified? Usually, any good service provider will offer some kind of guarantee or warranty for the work done by them. While it ensures that the technician gives his best to the job at hand, it also gives you peace of mind.

If your computer has slowed to a crawl, then you have errors inside of the Windows registry, which is the central database that controls many of the functions on your computer. The best way to fix these errors is to use a registry cleaner. But, you must choose the best one, because if you do not, you could end up with more problems than before!

A good registry repair program will fix each invalid entry quickly and easily. This type of program will also backup your registry on a regular basis, in case there is a problem, your registry will be restored to its normal status. A registry repair program will also perform a complete system scan to find entries that are no longer necessary or were never needed in the first place. It also finds holes inside the registry, and other problems. It will perform defragmentation tasks and checkup on your system regularly. And you also want a program that not only rides your computer of registry errors, but also removes spyware, protects against viruses, and fixes outdated drivers.

In order for your computer to work at its optimum level, the registry and other components must be in good working order. Just one problem can slow your system down in a very big way. If you want to prevent registry problems, scan your computer regularly, keep spyware, adware and viruses away, and keep the P-C drivers working and updated, you need a complete software system to achieve your goals.

What qualifications do good candidates for home computer jobs need? There are a couple of different ways to look at this. Do you have the personal qualities that would make this a good choice, and does your stage in life or lifestyle afford you the time to commit to a home computer job? You need to take a real good look at yourself and your situation, and be completely honest with yourself. That's not always easy. My firm belief is that no matter who you are or where you are in life, if you want something bad enough and can envision success, you can get there. But, if you're on the fence, here's a couple of things to consider.

Number one is, of course, time. Now, depending on your home business of choice, the time requirements are different. Rule of thumb being that the more effort going in, the more compensation coming out. A venture that you desire to make a full-time income will call for your presence. Are you willing and able to sit down and work at this for a set amount of time each week? Please be realistic here. Perhaps, there is another time-consuming activity that you could put on hold, or frankly, do without that that could allow you the time necessary to build your home business.

Where do you stand on self-discipline? Introspection can be a bit painful. Are you the type of person that will make yourself sit down and get to work without a hovering boss? Do you have the ability to forge ahead on a project that needs your undivided attention when fun or some other responsibility is our there lurking? Now, fortunately, one of the benefits of home computer jobs is that in most cases you can set your own hours, and work around your other activities. The allowed flexibility is great perk, but make sure that you use it to an advantage, and not to the disadvantage of your home business.

What about available capital? Again, thankfully, we have choices here as well. You do not have to pay much of anything if anything at all for a lot of home computer jobs. Some start out with a small investment and only call for more when and if you choose to do so. You need to shop around and find an option that fits in your current budget constraints.

Are you up for facing a new challenge and learning? You will be faced with this question in just deciding what home computer work to pursuit. I imagine that most good candidates for home computer jobs are or have done their research and want to make an informed choice and know what they are getting into. Desire and devotion to learning new skills, terms and technology are of great importance.

In summary, being a good candidate for a home computer job is a personal decision. Ultimately, you're the one that knows if this is a viable option for you. A few important considerations are available time, self-discipline, start-up costs and needed capital, and the desire to learn and take on a new challenge. Gauge your desire for something different against what it will take to succeed and always be honest with yourself.

Overheating: For a CPU that is overheating, you may check the PC health section of your BIOS. A healthy CPU fan generally runs at about 3000 to 5000 RPMS. You may also want to check your power supply and video card fan. A fan may be repaired by cleaning it (removing and unclogging dirt on its blades).

Computer memory: Widows typically detects a problem with your computer's memory and may start the memory diagnostics tool automatically. However, if you suspect that there is a problem with your memory and wish to start diagnostics manually, go to the memory diagnostic tool, which is under , Control Panel> System and Maintenance> Administrative tools . You will be prompted to choose whether to run the program on restart or restart and run later.

Errors on your Hard Drive: To check for errors on your Hard Drive, go to My Computer , right click on the drive, and click Properties> Tools and then click Check Now … You may choose automatically fix file system errors for a more thorough scan.

Outdated or poorly programmed device drivers: When your computer seems to predictably crash when you perform certain tasks such as play games, watch movies or plug-in certain hardware such as a joystick, the drivers associated to that task may have a problem. The first thing is to check for compatibility. Check if the drivers you installed meant for your version of Windows.

Corrupt files and programs: Corrupt files may also present problems in your system. A corrupt file is sometimes created when there is interference when you try to

The quickest way to find a problem is to always start with the most obvious cause. Generally speaking, hardware malfunctions are usually the most obvious and easiest to fix. Secondly, check if there is a pattern for the "crashes", especially if you have encountered several "crashes" before. For example, you may find that your computer tends to crash when you are watching movies; this may indicate a problem with your graphics card drivers.

What causes a computer crash?

A computer crash is a condition where a computer's application and or operating system ceases to function properly and exists, due to a malfunction in the execution of the machine instruction. The most commonly known computer crash is arguably the "Blue Screen of Death". These crashes sometimes occur at the least convenient time, like when you are about to finish an assignment or report, not to mention the time wasted when you try to restore the system.

Slow computer is an annoying problem if you do not know how to fix it. If you want to get away from slow computer, what you need to do is just to follow the 3 steps as following. Then, you can make your computer faster.

1.Check out RAM

Random Access Memory (RAM) is well-known. RAM is one of the most important components in the PC that enables you to store your main data. Thus, the data can be accessed instantly. Over time, you need to upgrade RAM because new programs require more RAM to run. It is difficult to run certain applications with a small RAM which has limited space. If you have a large RAM, your computer will run as fast as the new one. However, you have to spend more money upgrading RAM.

2.Defragment your hard drive

As a PC user, you should know the defragmentation. If you are not familiar with the defragmentation, your PC will be crashing or freezing. Defragmentation can enable you to arrange the files and programs which might have been missing or misplaced when you are using computer. Regularly doing defragmentation can clean up and invalid files and data from your PC so slow computer might be fixed. This utility comes with Windows.

3.Fix registry errors

Most computer users do not know what the registry is. The registry is the central component of the Windows. It stores all personal information details and programs settings. The data can be stored in the registry, but it can not be removed. As a result, the registry files and keys will get overload over time in the registry. This will cause your registry keys to get missing or damaged because they have been overwritten many times. In this case, your computer will have to spend much time opening programs. That means you get a slow computer. To fix slow computer, you need to clean up the registry entries and fix registry errors. The registry cleaner can get the job done automatically. It is not recommended you to fix the problem by manual due to it will damage your PC.

In the United States of America, you certainly hear the word "Apple", like millions of time. Apple in this context is not Apple the fruit, but it is a famous brand of gadget technology, and they are famous of the product of Macintosh, iPod touch, iPhone, and now iPad. The company now becomes one of wonderful growing computer company in the world, and this company also has been the factor of the rapid increase of personal computer. However, before seeing the huge succeed of Apple, we should flashback to Apple Company History. You will find it very interesting in seeing how the forerunners of Apple started their computer company.

Back to April 1976, Steve Wozniak and Steve Jobs established Apple after they dropped their college out. Their co-worker relationship started when Wozniak successfully created building boxes to make free phone calls for long-distance. This was the very first step of Apple Company History; since it was a huge invention at that time. The huge invention was because telephone, which was just founded, cost people very expensively. Wozniak himself is a super talented and self-taught electronics engineer; accordingly, his new invention bought him a great selling of the boxes.

Then, after experiencing a great succeed, Wozniak extended his invention again in 1976. He made another box which was called the Apple I computer. This type of Apple computer was not like as you see commonly nowdays. It had no keywords, and had not power supply either. However, pioneer Apple Company History made them sacrifice a lot of things to build it, such as selling their van and two calculators. The van and calculators could raise about $ 1,300 to set up the real company of Apple. With the huge sacrifice and devoted hard working, they were able to sell 50 units of computers in San Francisco Bay area, and the computers earned $ 666, which was already huge in that year.

Shortly afterwards, in summer Wozniak made another type of Apple, which was Apple II. This time, Wozniak's intention was not only to sell computers to local people for simple needs, but he wanted to develop a bigger market for his small computer company. The Apple Company History kept on going. In order to make this come true, Wozniak hired local computer 'engineers' that had enthusiasm and solid commitments to the company. Although he found out that they were high school students, they were just so in touch with the company to assemble circuit boards and design software. Besides, hiring those high school students, he also consulted with Mike Markkula to promote their products. Markkula was a retired computer engineer who had participated in the marketing of Intel Corporation.

Two years later, which was still 1978, Apple broke through as one of the most rapid-growing companies in the US. They were spread across the nation through 100 dealers. This succeeded keeps on going until right now, especially after Apple Company launched their new type of computer which was named the Macintosh, and other several sophisticated gadgets, such as iPad, iPhone, iPad touch, and the like. And after reading this brief explanation, the Apple Company History tells us why it now has big four operating divisions; they are Apple USA, Apple Europe, Apple Pacific, and Apple Products.

Okay so why write about it? Well because there was once a time that i needed to know how to connect two computers together and I could not find any articles to help me and no links on the internet that had it in detail, so this is for the people that might experience the same.

So let's begin!

Firstly you will need to know how exactly your two PC's are going to connect. So here it is. The computers will connect directly to each other therefore no hub will be needed. For those of you that do not know, a hub is just a device that connects computers in a network via UTP STRAIGHT THROUGH cables.

The reason why I wrote straight through in caps is because this is not what you will be using to connect the two computers. Instead you will be using cross over cables. You can get this from a local computer store for relatively cheap. Or if you feel like doing work then make it, its really easy. If you need any help, then a Google search on how to make crossover cables will help alot. The reason why I do not tell you how, because I'm telling you how to connect two computers not create crossovers.

Anyways that's all the requirements you'll need, just a cross over cable. (Please note; if you are buying or making a cross over, make sure it's at least cat5e UTP cables.)

Now that we got that out of the way, let's get to work!

Step1

On each computer, right click on "My Computer". Click Properties and then click on the "Computer Name" tab. Where it says "Computer description:" Give each computer a description (It must not be the same). Now click on the "change" so that you can change the name of the computer and create a workgroup. In the name option give it the same name you gave it for its description and in the workgroup section type in "my first network" (REMEMBER: Names of the computers should NOT be the same, BUT Workgroup names should be EXACT the same on both )
Now once you change these, you will be asked to restart the computer, so simply click yes or ok, whatever you are prompted with.

Step 2

After the computers are rebooted you will need to setup IP addresses for each computer. This is how:

On your desktop, look for the icon named "My Network Places". Now dpouble click it to open it.

Once open look on the left to see an option "view network connections" and click on it.

Now right click on local area network and click properties.

Where it says "This connection uses the following items:"; scroll down to "Iternet Protocol (TCP / IP)", click on it and click the properties button.

Now click on "Use the following IP address" and at "IP Address" type in an IP address eg 192.168.0.1.

Although you do the same steps for both computers you must have different IP addresses so you can make the second computers IP address 192.168.0.2

After you set the IP addresses just press the tab button and you should get a number in the subnet mask as 255.255.255.0, then press OK and wait a while and now you almost done!

Step 3

This is the easiest part; just take you cross over cable and connect to each computers network card RJ45 port. That's it you now will be able to see the computers in "My Network Places". You may start sharing files!

As a computer user I am sure you have heard of several different types of malicious programs that could get on your computer and do several different things. From speed reduction, file corruption and even hijacking your computer and all of these things and more can happen from something such as viruses, malware and spyware.

One type of malicious programming that is not discussed as often is one cited to as "scareware". These programs are often designed to mimic real antivirus and anti-malware tools and can also use screens that look similar to your operating system to try and convince you that your computer is seriously in need of their assistance to get rid of infections. At times they are also designed to terminate programs you want opened and hijack your internet browser all in the hope of scaring you into buying them. That's what the program Peak Protection 2010 is, a combination of spyware and scareware and you need to get rid of peak protection from your computer quickly.

The first sign that peak protection 2010 is on your computer is that for some reason your computer wants to reboot on its own. You may be prompted to reboot so that updates can be completed. You may also just have your computer reboot on you without even wanting it to. Once it comes back up you will get a screen that says that the peak protection 2010 software is going to scan your PC for malicious programs.

While this may not sound like a bad thing what is bad about it are the results it comes back with are always fake. Either they are small, harmless files placed there when peak protection 2010 was installed or they are files you need to run programs on your computer. None of these infections are even real. You will still be told that your computer is in need of help though.

You will also start experiencing programs that will either not start up when you open them or shut down randomly in the middle of working on them. You will also get messages that pop up on the screen that often says:
The program that you are trying to use has been found to contain a malicious program. The program has been terminated to in order to protect your computer security. To clean up this issue you will need to activate your copy of peak protection 2010. From this point you are expected to run, get your credit or debit card and purchase a copy of the software in the hopes of getting your computer working properly again.

Instead of doing this, you should start to get rid of peak protection 2010 before it causes real problems and compromises your credit card details and your passwords. In the long run, it will be easier and less expensive to do.

To get rid of this malware you will need to download a system and registry scanner. This will scan your computer for errors on your system and malware hiding in there. If you try to get rid of peak protection 2010 manually you will find it impossible to find all the files and there may be other malware and scareware on your computer that you do not even know about. By running a system scan you can find this is minutes and make your computer safer and faster. Run a system scan now and protect your PC.

HDD external hard drives are a storage solution for all your digital media and all your data data which can be used over a plug-n-Play with every PC or laptop around the world. They are an external variety of the internal memory of your computer and as such they can be easily transported and moved around, and usually they are quite small, too so they even fit inside pockets if you do not want to be carrying a bag around all day long. However you choose, you'll find a good external HDD which you can use on the go.

You might want to work on work documents at home, or to have school data with you at home, or simply to take your photo library to your aunt to make her see those wonderful vacation pictures you took last month. All these are possible by simply using an external hdd, and they're quite simple to do, too, because all you need to do is plug your hard drive in the USB connector and copy the files by drag and drop, no more effort required ! And it's a matter of seconds compared to burning CDs or DVDs with all these media.

External HDDs come in various capacities. If you only need it for documents, photos and so on, you'll be fine with the really small size like 200GB, where you can put more than a man can write in his own life! However, with more and more people using their computers to watch movies, listen to music and edit movies at home, you might want to have a look at the larger storage options like 2 or 3 TB, which is ten times as much as 200GB and which will be sufficient for about 2600 movies or 400.000 songs, more than you could ever watch or listen to, so do not worry about that!

It really is quite easy to use such an HDD external hard drive once you know how it's done, and it's a perfect solution for all your storage and mobility needs.

If you have not been in a coma for the past 10 years then you probably have a computer in your home. As the technology changes and improvements everyday it is becoming almost impossible for you to accomplish any task without the help of a computer. With the rapid growth of the computer industry there is also a rapid growth for the need of qualified computer professionals and this article will talk about where you need to go to get some basic computer education.

A computer center is the place you should go for basic computer education and these centers teach you a variety of things. Computer centers teach those in all different forms of learning from beginners to advanced computing skilled professionals. Other computer centers focus on teaching their students a certain operating system or programming language which will eventually make them experts in that area.

The most general computer courses you can take will teach you some basic skills with the operating systems such as Windows, Mac, Linux, or Unix. Other things that you will learn are some of the most used pieces of software such as Microsoft Excel, Word, PowerPoint, Internet Explorer, Photoshop, etc. The more advanced courses will cover topics such as graphic designing, system administration and network administration, security specialization, etc.

Like most schools computer education centers will vary in the size, teaching methods, and quality of the teaching. There are some centers that are only able to teach a few students while other schools are going to be able to teach hundreds. You should try to find a computer education center that provides you with basic computer education that is good quality while still having small classes. Just because the class is big does not mean it is the best quality plus you get less personal attention from the teachers.

Another factor when you are looking for a place to get computer education you should find places that have been certified by the leading computer companies. If a computer education center has been certified by the leading companies in the computer world such as Apple, Cisco, Microsoft, IBM, etc. you should join those schools because those companies have given permission to those schools to teach products that have been released by them.

Computer vision syndrome is becoming more and more serious as we all spend excessive hours in front of our computer screens. The average person can spend up to 90% of their workday at a computer, and then go home to work even more hours. This is can lead to stress in the back, neck, shoulders, and eyes.

Positioning your computer screen and keyboard in a more efficient manner can make a tremendous difference when it comes to overall comfort and one big tip can help your eyes.

For starters, your monitor should not be too far away or too close. If it is too far, you will begin to lean forward at your neck and put excess strain on your shoulders and back. If your screen is too close, your eyes will suffer as they constantly need to engage their accommodation muscles in order to maintain up close focus for prolonged periods of time.

Find the distance where you can sit comfortably with a relaxed neck and shoulders and still see the monitor clearly. You may also want to adjust the display size of your screen or wear computer glasses to take the edge off. Computer glasses are essentially low powered reading glasses that allow your eyes to relax, rather than continuously focus on the screen.

As far as monitor position, place the center of the monitor below eye level. When we focus up close for prolonged periods of time, we tend to slow down our blink rate. This leads to dry and uncomfortable eyes. Our tears naturally evaporate while our eyes are held open. If you look up, your eyes are more open and tears evaporate even faster. So having the monitor immediately down keeps your lids partially closed and will hold more moisture against your eye for a longer period of time.

By simply placing your computer monitor at the proper distance from your eyes and keeping it slightly below your line of sight, you will begin to notice more comfortable vision at the computer. This will also reduce strain that is often felt in your neck, back, and shoulders. Do not forget to look away and stand up every so often to give the rest of your body a break as well. Happy computing.

This article is the beginning of a thread of articles that give novice users a grounding in the Apple mac operating system. For those used to Windows computers the switch to Apple can seem daunting. It need not be. In this series of articles I will lead you through the transition from the Windows environment to the latest version of Apple OS 10.6, also known as Snow Leopard. Each article in the series will cover one specific area of ​​using the computer, and will give hints and tips that help you use your computer efficiently and effectively to meet your needs. Upcoming articles will include:

Finding the similarities between Windows and OS 10.6
The Desktop, Dock and Finder
Email using Mail
Browsing the Internet with Safari
Word Processing using Open Office
Using iTunes for music
Using iPhoto for photos
Connecting to networks and the Internet
Backing up your computer using Time Machine
Some free software to expand your Mac's capabilities

So, on to the first article. Identifying the similarities between Windows and Snow Leopard is a great way to get your bearings, and quell any fears about the size of the task ahead. The first place to Start on a Windows PC is the Start menu, and on a Mac it's really very similar. On a Windows PC you find the Start button in the bottom left hand corner of the Toolbar that remains visible by default on the bottom of your screen. On a Mac you click on the Finder icon on the left hand side of your Dock, which is also by default visible on the bottom left hand side of the screen.

Clicking the Finder icon brings up a window that looks very much like the Windows Explorer window that would open if you selected My Documents from the Start menu on your PC. The window has a number of familiar, similar features that enable you to navigate through your computer. In the left hand column of the window you will see three headings: Devices, Places, and Search For. Under Devices you can see your computer's hard disk, by default called Macintosh HD, an iDisk, and any others drives that may be connected to your computer such as a USB pen drive or external hard drive.

Under the Places tab you will again see many familiar features, including: Documents, Music, Movies, Pictures, Downloads, and Desktop. These names are self-explanatory, but for clarity you can relate them to the corresponding Windows folders: My Documents, My Music, My Videos, My Pictures, Downloads and Desktop.

To navigate through your computer you simply click the relevant name to see the files contained within that folder displayed on the right hand side. At this point you should experiment with the different view options that you select by clicking on the icons along the top of the window. There are four view options: Icons, List, Columns and Cover Flow. Icon and list view display the files within the folder on the right hand window. The Column view enables you to click on an individual file and see a preview of that file with information on what type of file it is, when it was created, what size it is, and even shows a quick preview of the file contents. Finally Cover Flow combines the list view with a preview panel and lets you click the left and right arrow keys to navigate through the files viewing the preview for each.

As with your Windows PC you save your documents, music, video and photos in the corresponding folders. In later articles we will explore the programs, or applications as they are known on a Mac, that you can use with each file type. The Applications folder in the Finder window is where all programs are saved on your computer, and you can open any program installed on your computer by clicking Applications and then double-clicking the relevant program, such as Mail if you wanted to send or receive emails .

There is another way to open Applications that is quicker and more user-friendly, this is called the Dock. The Dock is like the Windows Start menu and is by default located at the bottom of the screen. You have already found the Finder icon, and you can now scroll your cursor across the other icons on the Dock to see the name of each Application. Simply click on any of these icons to open the program. By clicking on the apple icon on the top left hand corner of the screen you can modify the way in which the dock is displayed.

Click the apple icon and hover over the Dock option. A pop-up menu appears and you can choose to Turn Hiding On, Turn Magnification On, change the position of the Dock, and go to the Dock preferences within System Preferences. System Preferences is the Control Panel of a Mac computer, and all settings in your Mac can be found and controlled there. Let's deal with the Dock settings first before looking at System Preferences. Hiding the dock means that it will disappear giving you a full screen to work on and will reappear when you move your cursor off the edge of the screen that the Dock is positioned on. In the default example with the Dock at the bottom of the screen you simply scroll down to the bottom of the screen and the Dock shows.

Changing the magnification alters the size of the icons as you scroll across the Dock. Within the Dock settings in System Preferences you can also change the total size of the Dock. If you have many applications on the Dock it can be easier to decrease the Dock size but increase the magnification. You can add applications to the Dock by dragging the corresponding icon from the Applications folder in the Finder window down to the Dock. Simply click on the icon and hold down the button, drag the icon to the Dock, and release the mouse button. All applications that are currently running will also appear in the Dock if they are not there normally. Applications that are open or running have white dot benefit their icon. To remove an application from the Dock simply click and hold the cursor on the icon and drag it across to the trash can on the right hand side of the Dock.

Well done, you've navigated around your Mac for the first time and found your Documents, Music, Videos, Pictures and Applications folders. You also know how to open and close applications, and how to add or remove applications from the Dock. In the next article we will go deeper on navigating through your Mac, opening and closing programs, and using keyboard shortcuts.

While most computer repair and data recovery technicians understand the need to keep up on the latest technology innovations and computer service techniques, it is equally important to any jobs success to bring the right combination of tools and supplies to every service appointment. Even an experienced PC or server technician can find themselves in a situation where they will need to travel to do a job where they do not necessarily know what they will encounter or which tools they may need once they get there. Following are the ten most important items for a computer field service professional to have with them on any job:

1. Hand tools. At least one large and one small standard and Phillips-head screwdriver.
2. ESD wrist strap. This is the single most neglected item by most computer service technicians and also the most important so as to prevent damaging any components through electrostatic discharge.
3. USB Flash Drive with virus removal tools. Often a technician will find themselves trying to service a single computer that is unable to connect to the internet due to virus or malware infection.
4. USB Keyboard, Mouse and Network Cables. While this is actually three items I have grouped them together as they are commonly needed for testing and ruling out defective input devices in the computer troubleshooting process.
5. Laptop or Netbook Computer. In many cases the technicians own portable computer will be the only way to get to the internet to download drivers, view manuals or look up a manufacturers technical support or warranty service telephone number. For network or server technicians this should also include a serial cable with which to connect to and configure routers and switches.
6. Wireless Router. Home wireless routers fail regularly, so a technician should have one with them at all times with which to replace the customers router if necessary.
7. PC Power Supply. Few items fail as often or are as easy to replace as the power supply. Having one with you will prevent you from having to return to the site to perform a simple power supply installation.
8. Flashlight. Since there are many low light areas inside the computer‘s case and within closets and basements where cable modems/routers are often set up, having a flashlight will eliminate frustration and make the computer service technicians job easier to perform.
9. Tie Wraps. While not critical to the repair job itself– keeping cords and cables neatly wrapped up and organized is one thing that distinguishes a computer service professional from an amateur.
10. Portable Air Compressor. While this item is the least practical to transport it should still be brought with to every computer service job. Many times it will remain in the trunk of the vehicle and not be needed, however should you open the customers computer case and find that it is full of dirt and dust a technician will need to have a way to clean it out.

Few things can be more frustrating or embarrassing to a computer repair or data recovery technician than travelling to a job only to find out that they haven’t got the right tools with them to complete it. By ensuring that you have these ten things with you on every computer service appointment you will eliminate frustration, maintain a professional image and prevent unnecessary repeat visits.

The article describes the procedure for removing a virus on a frozen computer. The methods described here are reliable and correct to date. However, we recommend you to follow them carefully to avoid running into problems. Alternatively, you can go for a professional online virus removal support service. It will save your precious time and money that could be spent lugging your computer to a repair shop or calling a technician at home.

Virus infections and the harms done by them are a reality today. It is also a reality that you can deal with them using a malware removal tool. However, what would you do if your computer doesn’t respond at all to your commands, making you unable to connect to the internet or access any application? You simply cannot do anything on a frozen computer. Feeling depressed? Don’t worry. There is a solution to your problem. The below mentioned guide will tell you the ways to defreeze your computer to eliminate the virus.

Instructions:

Press Alt, Ctrl, and Delete keys together to bring up the Windows Security window. Press the Shut Down button to let your computer start shutting down. When done, restart it. Instead of shut down, you can also simply choose the Restart option from the drop-down list on the Windows Security dialog box. Once the computer has rebooted showing up all the icons on the desktop, open your antivirus program. Hit the Update button to update the program with latest virus and malware definitions.

When done, run a full system scan (recommended) to search through all the directories and drives in your computer. If you run a custom scan (not recommended), it will only search the locations selected by you and not the entire computer. It is possible that the virus is hiding in different locations which you haven’t chosen to scan. It will not remove the virus fully which can re-execute itself from there. When scanning is finished, prompt your program to delete the infections.

Thereafter, download and install Malwarebytes’ Anti-Malware from its official website. Save the downloaded file and unzip its contents to another file provided that it is zipped one. Run the setup file and complete installation of the program. When done, open Anti-Malware and update it. Wait until updating finishes. When done, run a full scan as mentioned above and then prompt the tool to delete the virus infection.

If the Alt + Ctrl + Delete method doesn’t work for you and the computer remains frozen, force it to shut down by pressing the power button off. Let it remain powered off for some time like 5-10 minutes. Now power it on and while it starts rebooting but before the Windows logo appears, start tapping the F8 key to boot it into the Safe Mode with Networking. Use the Down arrow key to make the selection. When done, repeat the abovementioned procedure to eliminate the virus from your computer. You can also manually remove the infection; however, it is a risky and lengthy procedure as it involves deleting virus files from the root directories and modifying registry. You must rather contact an online virus removal support service before taking the risk on your own.

If this method also doesn’t work, exercise this one. If you have another computer which is virus free at your home, use it to download Malwarebytes’ Anti-malware. You can also use your friend’s computer to do so. Save the copy to a flash drive or a CD whichever your infected computer supports. While this procedure is being performed, power off your infected computer. When done, plug the media to the port of your computer (infected) and choose to boot it from. Follow the on-screen instructions and repeat the process of using Malwarebytes to clean your machine. When finished, save the copy of Malwarebytes on your computer and take the media out.

Additional Tips:

We haven’t explained the manual virus removal procedure here. It is well explained in the article why the procedure was not included here. If you want the painless and hassle-free treatment for virus removal, contact an online virus removal support.

Virtual pets are simply clever electronic simulations, but children can find it very satisfying and engrossing taking care of their virtual computer pets. Indeed, some of these pet simulations feature very high levels of sophistication to make caring for them very involved and rewarding.

The ultimate penalty for neglecting virtual computer pets is that, without enough care and attention, they will ever die. This means you will need to devote quite some time to developing them, ensuring they're fed regularly, and continuing to entertain them, just to keep them alive and happy.

In order to play with virtual computer pets, the choice is huge, as there are many online virtual pet sites where you can choose from an extensive range of pets. But the great thing about playing with computer pets is that there's never any damage or mess to clear up. Of course, you'll also have hours of fun interacting with your pet.

As a parent, you'll have no concerns over vet bills or buying food for your pet – just press a button instead. It's a cost-effective way to teach your children to be responsible and put effort into caring for a pet before actually going out and buying a real one.

You're not just limited to virtual computer pets, of course. You can download virtual pet programs to your phone or play them on portable game consoles. For the ultimate in portability, there's always the standalone Tamogotchi.

However, if you're playing The Sims 2 – Pets on the PC, you can even indulge in a little cheating to make your life just that bit easier.

The cheat mode in The Sims is entered by pressing CTRL + Shift + C, all at the same time. A cheat window will appear at the top of the screen – and you can now type in one of the following cheat codes:

maxMotives – this will boost all your sim's needs into the green

Many people refer a damaged computer with a lengthy journey to the neighborhood computer repair business. However, in recent times, the mobile computer repair industry has seen a sharp rise in demand services. This is due to the busyness of the average working lifestyle increasing by large amount. With working professionals having to take on more work, they therefore have less time to spend at home and to carry out activities. If you're a working professional, then you likely value your time a great deal, and may see taking your computer to the repair store as a bit of a hassle.

Fortunately, mobile repair providers are generally here to help. In almost every community, there's a computer repair business that is able to do residential home visits. Not only is an in-home technician service seen as a given in a modern society, but the time efficiency of such work is far greater than that of taking a computer directly to the store.

You'll likely find that if you obtain a repair professional to come to your home, the issue is resolved in one appointment. This is due due to the initiative by mobile computer repair companies to carry out work as efficiently as possible. Not only does this make work more cost-effective for the business, but it also makes it more cost-effective for the consumer.

Conversing regarding companies, your mobile computer repair community has a large range of small business consumers inside its customer base. Business clients hold a large amount of computers in today's society, and therefore there are many more issues to be found in corporate computing, then there are in-home computing; generally speaking.

The added advantage of your repair providers for firms is that they do not have to employ associates, or get their existing associates, to take IT products to computer repair depots.

Business consumers may also value the convenience of such a program as, the caring devoted assistance of a computer professional through a procedure enables a great deal more work to be completed than if it ended up having to be taken in to a depot. Turnaround time is the most important businesses, generally speaking, as IT equipment is often mission-critical for getting a project completed.

Regardless of whether you happen to be a consumer or a business person, you will certainly discover a number of important benefits from your local mobile repair companies. This is not to say, however, if you do have the time to visit a computer repair store, you'll likely find you get a great customer experience when it comes to taking a trip down to the local computer repair store. Part of the reason why customer experience is generally greater at a computer store, is due to the fact that many repairs take place at the depot itself. If you have access to all of the staff services at a computer store, you're more likely to see a wider range of options for your job.

Inevitably, it is up to you to determine whether or not a mobile computer repair fits you, or if you will be considering better off proceeding to your local computer repair shop. One thing to bear in mind, however, is the fact that you have to realize whether it's better to value cost, or to value time. The most cost efficient method would be to go directly to the store, however, if you value your time more; then mobile computer repair is most likely going to be your answer.

Computers are our world's gateway and information super highway yet they were not always so complex, integrated and involved in our lives. The computer has been slowly developed over centuries and has taken the skills of many inventors. In the search of formalizing a counting mechanism, the concept of positionality notation was introduced. In or around 3000BC the Chinese abacus was developed. The abacus was the only computing device in history for over four thousand years. In the 1600s German scientist Wilhelm Schikard invented a device that used eleven complete and six incomplete sprocket wheels that had the ability to add, multiply and divide.

It was not for another three-hundred years that the world first programmable computer was built. The Z1, created by Konrad Zuse in the late 1930s, had all the basics of our modern day computers, such as use of the binary system and separation of storage and control. Unlike the devices we use today, the Z1 weighed a little over two thousand pounds. Like the Z1, the ENIAC was very large; its size equaled to that of two semi-trucks and weighed over thirty tons. The ENIAC was built in the US in the mid 1940s by John Mauchly and J. Presper Eckert and was the first electronic computer.

Over the next few decades the development of computer devices transformed from a machine that took up every bit of space in a room to a device that is as portable as a cellular phone. The Apple and IBM Companies built the first recognizable computers in the late seventies and early eighties. As years go by the size and speed of personal computers have changed for the better.

The internet as we know it has only been around in the last twenty years, yet we depend on it like the air we breathe. The World Wide Web (WWW) was developed by Tim Berners-Lee in 1991 and since then has continuously added websites and services that were previously not available to a person from their home. There are a number of things available to you on the Net, you can find anything from simple word definitions to integrated personal or Corporate Training Solutions .

One of the items we, as the latest generation, can say is imperative to our everyday lives is a laptop. Due to their small size and portable functionality, people are able to do almost anything from a number of locations. This feature motivates businesses to offer Enterprise Learning Solutions to their employees. With the flexibility of such devices learning on and off the job is as simple as pressing the power button.

It's understandable that loads of PS3 gamers are curious if it's possible to copy PS3 games. It's a topic that pops up frequently since numerous gamers would like to copy their video games, but are not sure how to go about it. In this guide we're going to go over exactly how you can burn PS3 games.

I believe it's very important that we point out that we are not doing this so gamers burn video games they do not own. Having said that, it is generally legal to burn what you already own so you can save them from getting damaged. There's nothing more frustrating than losing a game you bought simply because it unintentionally gets scratched.

Let's get to it! If you're wanting to burn PS3 games, you'll have to utilize a piece of software intended to copy. These types of programs have been produced specifically for people wanting to copy video games and are not the same type of software as what you would use to copy a movie or music CD. Numerous PS3 owners get tried using an ordinary CD copying computer program just to learn that they wasted a blank disc.

The reason that typical CD burning programs can not burn PS3 games is because the discs have got copyright guards on them. Your computer system can not make sense of the data on the game discs when these protections are on the games.

Fortunately, there are now programs that have advanced technology that can get around these guards. Specialized video game copying programs let your computer look at the data on the disc and copy the game. You just have to install it on your computer system and can then burn a PlayStation 3 video game anytime you wish.

Luckily they're very easy to use. You toss in the video game, let your computer create an image of the files onto your hard drive, then put in a blank disc so that the information is moved. When it's done you end up with an identical copy of the original game. It will take about 15-25 minutes to finish off based on your computer system.

You can get a top quality program for less than the price of one game. You should never have to pay out over $ 40. A quality program will also offer you a moneyback promise so that you are sure that you can get a refund if there are any difficulties.

Burning PlayStation 3 video games is a great method to safeguard your video games and a trick that each game player should have as an option. Anyone that has a PlayStation 3 can make use of this type of software program to take care of their video games.

In today's data driven world, computer data can be very important to us, especially for those who use a computer to make a living. The best way to prevent such a loss is to back the data up by copying it to an external storage file a minimum of once a week with once a day being the recommended frequency.

One way to back up your important data is to burn it onto high capacity CD or DVD disks. And if you use CD / RW or DVD / RW disks you'd be able to add more information after the initial back up.

Whether you want a full data backup, or just copies of specific files and programs, backing up your data can save you a lot of aggravation, time and sometimes money by keeping your computer data safe.

The type of backup you decide on depends on what you use your computer for. Personal data may not be as critical as business data that keeps track on who owes you money or what orders you need to fill from your inventory.

There are five main methods that can be used for backup. They include the following:

• Full backup – as it follows, the whole hard drive is copied on a frequency the user chooses. This method may be the most beneficial for the many functions of a business.
• Differential backup – is used for file that have been changed or upgraded. A computer used for controlling inventory or tracking investments might benefit from the method.
• Disk imaging – Can be used for either back up of the entire hard drive or specific files that the user chooses. This is one of the most versatile methods.
• Unattended backup – This allows the user to set the backup software to copy the files the files he / she chooses even if they are not there to monitor the backup.
• Snapshot backup – This will mirror your hard drive at a specific instance so data at that time can be easily reproduced.

A few things to remember when choosing software for the backup method you need; price is definitely a factor but its best not to skimp if your need for reliability is critical. Also, most backup software is easy to use even if you're a computer novice. It comes with directions that are easy to read and understand.

The best remote backup systems are internet based. This means that the backup program sends the data to an offsite server on a schedule you set, usually in the evenings when the computer is idle. These services provide excellent security and adequate storage space for your data.

It's prudent to research remote backup services and purchase only the features that you think you'll need for your situation. Features such as expandability, security and disaster recovery will help get your computer up and running after a crash.

Many remote backup programs offer free trials and demos. It's a good idea to take advantage of these offers before purchasing a remote backup system for your computer.

The German engineer, Konrad Zuse is accredited with building the first computer in 1938. Zuse named his machine V1, but later changed it to Z1 to avoid it being confused with the V1 rocket. The Z1, was the worlds very first freely programmable computer. The Z1 was equipped with all the basics of our modern day machines, it used the binary system, a control unit, memory, micro sequences and floating point logic. The Z1 did not use relays, but instead consist of thin metal sheets, which was produced using a jigsaw. It had an electrical engine, which provided a clock frequency of 1 Hz. The Z1 had a 64 word memory, in which each word contained 22 bits. The arithmetic unit ran four basic operations, addition, subtraction, multiplication and division. The Z1 had an average calculation speed of five seconds for addition and ten seconds for multiplication. In order for the Z1 to be programed it required that the user insert punch tape, a long strip of paper with holes that were used to store data, into a punch tape reader. The Z1 was built in Zuse's parents living room and weighed a little over two thousand pounds. It was privately funded and while it did not function for any practical use it was the beginning of the development of a series of Z machines.

Even though Konrad Zuse has been given the title "Inventor of the computer," many consider the US-built ENIAC (Electronic Numerical Integrator and Computer) to be the first electronic computer. It combined the speed of electronics with ability to be programmed. It had a calculation speed 5000 times per second for both addition and subtraction, which was faster than any other machines developed before it. Like the Z1, the ENIAC was able to multiply and divide, but had an additional feature of being able to provide square roots. Unlike the Z1 the memory was limited to about 20 words. ENIAC was a very large machine, it was the size of approximately two semi-trucks had a large number of blinking lights, required what seemed like an army of attendants, weighing nearly thirty tons and containing over 18,000 valves. ENIAC was built by John Mauchly and J. Presper Eckert and funded by the University of Pennsylvania.

New Computers are equipped with numerous depths of programs and software. Windows 7 is the newest piece of software to hit the market.

Every computer acquires in its life, unwanted junk inside its hardware. This comes from downloading different programs or using websites that can cause spam that will plug up your memory. When this happens, it causes your computer to run at a significantly slower speed, resulting in a frustrated user.

There is even the possibility of harboring dangerous computer viruses without even knowing it. The good news is that with a Registry Repair Tool you can save your computer and save your hard drive.

When using a Registry Repair Tool there are some things that anyone should know. Using a safe link is essential. People search the Internet for a reputable scan but they do not know that to get the full scan you have to pay for it. There are many free scans that will do a partial scan of your computer and then tell you afterwards that to have the complete scan you need to buy the whole product. It can be a very frustrating feeling.

The best thing that you can do is to do your homework and research for a reputable repair tool. Look at their testimonials. Look at the credentials and make sure that people who have used the repair tool before you, are satisfied customers. If you see that it has a lot of good testimonials, even a partial scan will help your computer.

Finding a reputable scan is something that you should take seriously. Taking care of your computer can be as easy as asking a friend what Registry Repair Tool they use. This provides you with an ease in trusting a program to take care of what you value. When your computer holds dear the things that you need in life such as your personal bank information, important documents and personal pictures and music, you have to take the initiative to protect those things. A bad repair scan, or worse no scan at all, can take away all of those things in the blink of an eye.

With the right Registry Repair Tool, all of those things will be secure and taken care of and your computer will start to run quickly and smoothly again as well.

STUDIES SHOW THAT A VIRUS INFECTION IS NOT GENERALLY ANTICIPATED BY THE SMALL BUSINESS COMMUNITY!

Hackers of the world, rejoice! I read recently that eighty percent of the small business community have obtained free virus protection, which is widely available on the internet, and those same hard-charging business warriors do not anticipate having their computer systems becoming infected with malware of any type. Even though attacks on businesses are growing every year by the tens of thousands.

Actually, some of these small business owners have indeed been infected but the malware that infected their computer systems chose not to leave overt signs. The hackers out there sometimes would rather just enjoy their breaking and entering and they want to be free to re-enter at will. They will at least have bragging rights. Keep in mind that the people they brag to will want also to get into your private areas and may just decide to not only do serious cyber damage, but may also be sure to send all kinds of malware to people from your address book and make you look like a dope.

So today let’s talk about some of the signs of being infected with a virus or viruses. How can we tell if it happened if your hackers don’t leave an advertisement of their entry?

You may wake up tomorrow and have a few favorite customers call and laugh about the animations on your web site. You might even have pornographic cartoons moving about your site. There is all kinds of ways to make you look incompetent and these people are quite well versed in their Black Arts.

But back to our discussion. How indeed can you tell? What are some of the tell-tale signs that we might notice, at least before the porno figures begin cavorting wildly?

SIGNS OF A VIRUS INFECTION IN YOUR COMPUTER SYSTEM!

1. You might notice a change in the length of some of your programs.
2. It will be pretty obvious that your time loading will increase significantly.
3. You will note slower (sometimes much slower) system operation.
4. Watch carefully as you will notice changes in the file date or time stamp.
5. You will see reduced memory or disk space.
6. You will note bad sectors on your floppy (many systems use these).
7. You will find unusual error messages.
8. You will possibly have unusual screen activity.
9. You will find failed program execution.
10. You will note failed system bootups when booting, or accidentally booting, from the A: drive.
11. You will find unexpected writes to a drive.

Please keep in mind that when you find one or more of these, you might not have been violated by malware. Sometimes strange things just happen and glitches do happen for sure.

It is of the utmost importance that you know what to do if you suspect you have been violated by viruses. Your IT person can give you a lot of possibilities, but it is important to determine if you have been infected by viruses or not.

WHAT TO DO IF YOU HAVE A VIRUS INFECTION

If you conclude that you do have a cyber infection, the normal reaction is to use a new anti-virus program and depend on it to clean up the infected file. Bad idea! Most experts I know suggest that you replace the program with an original clean version.

Why take chances? You probably became infected by depending on one of those free anti-virus programs available widely on the internet. They are free and often worth that exact amount.

If you know it or not, viruses are out there and viruses want you. And they will have you if you don’t take steps soon. YOU have to do this. No one is coming to protect you. Only YOU can do it.

Next time we will discuss some exact steps to take after you determine that you do indeed have a malware infection. Malware can be quite complex or it may be simple. It doesn’t matter. You must address the problem.

Protect what you’ve built! Stop them today! Your computer system depends on you to protect it. It has no one else. Can you step up to the task?

Thank you for coming.

Computer users, rough speaking, fall into one of several categories. Here is a brief summary.

Extreme Users:

Extreme users spend nearly every waking moment in front of a computer and do so voluntarily. These folks are completely techno enthusiasts. They tend to be attracted to such things as web design, gaming, programming, computer graphics, etc. They use the computer as a tool and as a form of recreation. Their lives are intertwined with the internet. These are people who would be lost without a computer. They always want to have the latest and fastest computer and are willing to pay top-dollar for it.

Heavy Users:

Heavy computer users are individuals who tend to use computers for a work-related purpose. This alone consigns them to life in front of a computer screen. They spend around a 3rd of their lives in front of a computer. They tend to become adept at using various applications. They tend to develop decent typing skills out of sheer repetition. Heavy computer users are not necessarily techno enthusiasts, although they can be.

Moderate Users:

Moderate computer users tend to use computers for a variety of everyday tasks, such as finding movie reviews, checking account balances, email, word processing and so on. The people who are not afraid of technology, but at the same time, not techno enthusiasts. Computers are much like any other appliance – something to be used to accomplish a particular task, or even for general enjoyment. Web browsing is probably the most popular activity for moderate computer users. They posses a basic level of computer knowledge.

Casual Uses:

Most casual computer users tend to use computers infrequently. It's not uncommon for many casual users to have spent most of their lives in the pre-computer era – ie, pre-1980's. Many of these folks simply do not appreciate the need for a computer since they have sent a major of their lives without one. They tend to use them only when necessary, for example communicating with children and grand children. They tend to be technophobes who do not adapt to technology easily. Having a computer with the latest and fastest processor is not important to them. They are fine with using cheap used laptops and even antiquated systems like desktop units with Pentium II chips. These are not the kind of individuals you'll find in the computer section of Best Buy.

A computer in its most simple definition is a device for computation or a programmable machine. There are many discrepancies in answering the question of which was the first computer invented. If a historian is asked they might tell you that the first device for computing was developed in Asia about 5000 years ago, which aided is and is known as the Abacus. However, the first modern computer, as we know it, was invented during World Ward II.

The very first programmable computer (the Z1) was built by Konrad Zuse in 1938 after resigning from his job as an engineer for and aircraft factory in Germany. The Z1 had all the basics of our modern day machines, such as use of the binary system and separation of storage and control. The Z1 had memory for 64 words, which meant that each word contained 22 bits, and a clock speed of 1 Hz. In order for a user to program the Z1 it was required that the user insert punch tape, a long strip of paper with holes that were used to store data, into a punch tape reader. Although this test model never functioned for any practical use due to imperfections it was the beginning of the development of a series of Z machines that soon led to the development of the Z3, which was the first computer that was both freely programmable and fully automatic.

Like the Z1 the Z3 read programs off a punched film. The Z3 was built with over 2,000 relays (electrically operated switches), had a clock speed of about 5 to 10 Hz, and also had a word length of 22 bits. The computer used binary numbers as well as floating point arithmetic and could convert decimal to binary and back again. The Z3 was completed and successfully presented to scientist in 1941 in Berlin. Unfortunately the original Z3 was destroyed by an Allied attack in 1945 (In the 1960s a replica was built by Zuse's company and is on display permanently at the Deutsches Museum).

Another first in computers was the ENIAC (Electronic Numerator, Integrator, Analyzer, and Computer), invented by J. Presper Eckert and John Mauchly between 1943-1946. The ENIAC was the first digital computer. This computer was massive in size, it was about 1,800 square feet and used about 18,000 vacuum tubes, and weighed between 30-50 tons. The ENIAC capable of adding 5,000 ten-digit decimal numbers per second, contained 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and around 5 million hand-soldered joints.

Technology continues to advance and there is constant upgrades being made to computer devices and computer software. The latest upgrade to reach the technology market is Microsoft Windows 7 . Learn how to use this new upgrade with Windows 7 distance learning .

The Acer X243HQ is a magnificent monitor for those who enjoy pc gaming. It is a large 23.6″ in size and supports High Definition imagery such as Blue-Ray Disk formats and High Definition games. It also comes with a HDMI Adapter which enables it to be used with High Definition gaming consoles such as the PlayStation 3 and the Xbox 360! The thin design is eye catching while also being space friendly.

This fantastic monitor is also cheaper than most of its competitors and I highly recommend this monitor to any person interested in PC gaming or digital home media.

I have had the privilege of owning one of these beauties for around 5 months now. I have had no problems with the performance of the monitor or the support from Acer. Being a gamer myself, I have played numerous games while testing my graphics card and my monitor to see where its performance lies. It has certainly not disappointed when I have pushed the graphics to the limit, showing all textures and lighting as if I was there. This monitor also produces a great image when playing High Quality Movies and Blue Ray movies. The colors shown are far from pixilated and everything on screen looks sharp and crisp. The large 23.6″ monitor supports 1920 x 1080 resolutions while also supporting a refresh rate of 75Hz, more than enough for any average house hold.

When dealing with prices, you have to compare to the products main competitors.

The Acer X243HQ’s main competitors in my opinion are of the 24″ monitors produced by Dell, Samsung, Benq. The cheaper Benq offers many of the features the X243HQ has although I don’t like the glossy edging which produces glare when a light source is shone on it. It also doesn’t look as “sexy” as the Acer with its round base. Acer X243HQ computer monitors are also cheaper than the 23.6″ Samsung 2494HS although it does not offer speakers in the monitor. If it is being used for a home theatre or for gaming though we all know that these kinds of monitor speakers will not suffice. Overall, this monitor is valued at $239 Australian at MSY… A bargain in my eyes.

If you ever have the money to buy one of these monitors then I suggest you buy one as soon as you can! This monitor will mainly be for those who are using their computer for gaming purposes and I have to re-assure you that this is an excellent computer monitor with fantastic support from Acer.

When some computer owners notice after about 6 to 8 months that their machine's speed has noticeably noticed from what it was initially, they got worried that it is near its life span and ditch it to buy another brand new one. The speed of a computer decrees more as a result of new programs installed and the type of programs that you run; more than over a question of age, especially when it is still not even one year old. The difference in speed will be more evident in a computer that came with a modest RAM (random access memory) capacity stated in megabytes (MB).

This type of problem could easily be enhanced by enhancing the RAM so that it could load and handle many programs simultaneously without any appreciable loss of speed. In a conventional computer, upgrading the memory (RAM) is something a lot of computer owners can handle on their own while laptop owners may refer them to authorized service agencies. RAMs come in rectangular thin strips called chips or modules that fit into the grooves in appropriate slots on the motherboard. You will have to know the type of RAM used in your computer such as SD, DD (I) or DD (II), required speed and whether its parity or non-parity, before ordering. A computer generally has about 3 slots for memory modules that come in 128, 256, 512 MB or 1 GB capacities. (All this information could have been from your user manual, the manufacturer's website or a service technician if you do not have that knowledge yourself). However, there are websites such as Ramvalley.com that scan your system online and recommend how much of RAM to upgrade to.

The difference that a small increase in RAM could do to your computer is tremendous; and could easily make your computer you almost ditched to spring to life and pull along healthily for another couple of years or more for a small cost compared to what it would have cost you to buy a new one.

Talking of memory upgrades, what first comes to your mind is what would be the ideal RAM for your machine. That depends on the type of use to which you put the computer. Gaming, graphic designing and video-editing programs need a lot of memory power to operate at reasonable speeds whereas word processing, spreadsheets and general internet browsing, chatting etc. do not need extensive RAM to operate at acceptable speeds even if all those programs were to run concurrently including an added anti virus program running in the background. 512 MB is quite adequate to run all the latter programs simultaneously in the Windows XP environment where 1 GB would suffice in the case of the former programs. You may go up to 2 GB of RAM if you are engaged in lengthy video editing, downloading multiple videos simultaneously, running advanced videos or uploading videos to YouTube, etc. You must have a built-in graphic card of around 64 to 128 MB for satisfactory results. In laptops, the graphic card is generally integrated into the motherboard and can not be upgraded as in desks.

RAMs could be purchased according to brand names from any stores selling computer parts and accessories. Ensure the compatibility of the specifications of RAMs to be added with those of your computer, notebook or laptop system. This could possibly have already verified with online scanning as stated above. You should also check if returns are accepted and the amount of the warranty period.

A lot of people want to know how to copy shows from their DVR to computer. This is understandable because it allows you to make your entertainment more portable. In this article, we will explore the various ways to do this.

My friend Bob who has a DVR that was provided by his cable company recently ran into a problem. He ran out of disk space on his DVR and he did not want to delete any of the shows that he had stored on his DVR. He had recorded a lot of the latest Top Online Movie Rentals and definitely did not want to lose these. However, in order record any new shows to this DVR, he would have to delete his current shows or come up with a better solution.

My friend Shelia was in a different boat. She travels incessantly for work and loves to watch her favorite TV shows while she is traveling. Her favorite TV show is Southpark. Shelia said to me, "Richard, I have all of these shows stored on my DVR. Is there anyway that I can transfer these shows to my best selling laptop and watch them while I am on the road?"

Shelia and Bob each have different issues but their needed solution is the same. They somehow want to transfer from their DVR to their computer.

Today, I will tell you how to do that.

There is an ideal solution to this problem but, in most instances, it does not work. Here is the ideal solution. Your DVR, like your computer, stores information on a hard disk. So, it would be great if you could just copy the shows stored on your DVR to the hard disk on your computer or laptop. Unfortunately, for various reasons, you can not do this most of the time.

Thus, you need a different solution.

To put shows from your DVR onto your computer, you need to capture the video from the DVR into the computer. If your computer has a Firewire port on it (some come with this built-in) and your DVR does, you are good to go. You simply need to connect the DVR and computer with a Firewire cable and use a program called CapDVHS to capture the video playing on the DVR.

If you do not have Firewire port, you will need to buy a video capture card with input ports that match the output ports on your DVR-most people use the component RCA ports but you may be able to use HDMI, S-Video, or DVI as well. After you get this video capture card, you will then connect your DVR to your computer through one of these ports. Finally, you can either use the CapDVHS program to capture the DVR recordings or, ideally, use the program that was included with your video capture card which should have all the software necessary to capture the show from your DVR and put it on your computer.

In summary, though it would be great to simply copy shows directly from the DVR to your computer, this usually can not be done. You need to "capture" the video that is playing on your DVR to the computer using a video capture device on your computer.

Once you get the hang of it, it is quite easy to record entertainment from your DVR to your computer and it will allow you to take your entertainment on the road with you.

Computer viruses can cause a lot of damage to your computer. Having an anti-virus program is not enough to keep your computer free of viruses. After seeing too many people experiencing this problem on a regular basis, I decided to help you and others get rid of viruses for good. There is no need to shell out big bucks for one of the other commercial anti-virus programs!

Follow these 4 simple rules and your computer will be virus free:

1. Make sure you have a good antivirus program

I’m going to make this simple for you. If you are using your computer for personal (non-business) use then you need to be running Microsoft Security Essentials or AVG Free Anti-Virus (do a quick search on Google for both and download either one for free), and start running it immediately.

Alternatively, if your computer is a business/work computer then go ahead and download NOD32 – it is more than worth the purchase price.

Make sure you are running one of these programs.

2. Keep that anti-virus program up to date

This is the biggest mistake that people make when it comes to keeping their computers virus free. Having the program is not enough. You need to make sure that it is up to date. People are out there as we speak creating new viruses. You need to have your anti virus software up to date so it can fight all of these new viruses.

3. Run regular scans

Set your anti-virus program to run a daily scan at a time your computer is actually turned on. It’s no good scheduling it for 3 AM daily if your computer is not usually on at that time. Make sure those scans run daily. On the weekend, run a full system manual scan yourself.

4. Do not open e-mail attachments unless you are 100% certain they are legitimate

This is a huge part of the problem. Joe gets an e-mail from his brother Gary and it has an attachment. The e-mail tells him to “check out this cool file – it’s hilarious”. Joe convinces himself that it cannot have any viruses because his own brother would never do that to him. WRONG! In many cases, the other person has no idea they are sending you that e-mail. It is automatically generated by a virus or worm on their system. Do not open any e-mail attachment unless they have been clearly mentioned in the e-mail in a way that assures you that the person intentionally sent it. Even then, you should still save it to your desktop and scan it for viruses.

That’s it. Stick to these 4 rules and you will have a computer that runs fast and is virus free.

If you’re a computer enthusiast and you’re creating your own machine or shopping for a case for one, you should look into aluminum cases as a good option for protecting your computer while keeping it stylish. There are plenty of things to think about before you decide on the case that’s right for your box!

Aluminum is a good choice for a material because it’s incredibly strong and durable. You’re not likely to break your computer if it’s got a metal shield around it. You can find high quality cases that are built out of hand crafted aluminum making them truly excellent pieces. You’ll find that your machine will look nice and neat when put inside an aluminum case.

The prices for cases can vary from under $100 to over a few hundred so think about what your budget is before you get excited about something that may be out of your price range. You can get a sleek simple design for cheap if that’s all you want, but if you want to go in for fancy features, that’s an option as well. Choose your price range before you decide on what you want.

Some of the cases available are designed with specific uses in mind. For example, some put cooling and graphics cards at the top of the list, because those are the most important features for a serious gamer. If you expect your machine to get a lot of use and to heat up, you’ll want to make sure you buy something with high quality fans to protect yourself from overheating. If these aren’t important characteristics for you then go for something else.

Another obvious factor that you have to consider is how big you want the case to be. Where do you plan on putting it? Make sure that you know how big your computer is, or how big the space you wan to keep it in is. There are cases out there designed to be super compact if going small is important to you. Either way, make sure you get the right size.

Looks matter! Just because you’re wrapping up your pride and joy in sheet metal doesn’t mean it has to be ugly. There are aluminum cases out there in tons of colors and designs. And if you’re particularly proud of your PC’s innards, there are designs with clear side panels so you can look in on your creation and everyone can appreciate it as well.

You also want to keep in mind whether you want easy access to your computer. Lots of models have card readers and USB ports positioned on the front; does it matter to you where they are? Do you want the motherboard to slide out easily and conveniently? Ask yourself these questions before you make your purchase.

Aluminum cases for desktop PCs are an excellent investment because you’re buying a necessary protective component for your computer. You want to do it right the first time. Choose something you won’t mind looking at that’s functional as well.

There are many instances where purchasing new electronics is best. This may not always apply to computers. Buying used computers often offers many benefits over buying new. I have had several of each and have come to prefer used over new for many reason. If you are looking for a computer then read this first before you decide if you want a new or used computer.

Refurbished is another term for used. The difference is that these have at least been tested by professionals and possibly redone as well. You can usually count on them at least having a fresh installation of the operating system when you receive them. With these you can usually be sure they will be in good working condition when you receive them. A lot of these also come with at least a limited warranty.

While most used computers will be in good working condition, it is still advisable to test them if possible. If you are buying online and no warranty is offered then you should be very careful about what you buy. Do not be afraid to ask questions so you know what you will be getting. It's important that you will be happy with your purchase. It's also a good idea to know you will be getting everything you need. You may find it is much cheaper to buy the monitor and tower together rather than separately.

You may want to get a computer that comes with a restore disk. If you do not have this and you ever have the need to reformat your computer then you may have to spend a lot of money to buy an operating system. The restore disk will restore the computer to the original setting but anything you have downloaded or saved may be erased.

Warrants on new computers really are not as great as most people think. Most stores will not accept a returned computer for any reason after 15 days. Past that time you have to call the company that made the computer and they will send you parts or ask you to send the unit in for repair. This can be a headache and take forever to get your computer back to running even if the company does as promised.

While I have known a lot of people who did not have problems with the warranties, I have had a lot of problems in this area. I have had so many problems with this that I have come to prefer to just buy a used computer and then fix it myself if needed. This tends to save time and money for me. Of course you need some knowledge of computers to do this.

The main difference between new and used computers is that another person used them before you did. While you should make sure that the computer will do everything you may need it to do, that does not mean you have to buy it new. You can often find used computers that are just as good and reliable as new ones.

If you are looking for a computer then you can get a great deal on used computers if you shop around a bit. These tend to be much better deals than the ones you can find at leading electronics store and with the money you save you can buy as many as you like.

Computer fatigue syndrome is becoming more and more endemic as computers become common place in every day life, whether we use them for our jobs, entertainment, research or school.

If you find it hard to work at your computer for long periods of time and are plagued by symptoms such as eyestrain, blurred vision, dizziness & headaches, red, dry or burning eyes and low energy you are experiencing symptoms of the syndrome that has become Known as computer fatigue.

Most people just do not realize how enervating working at a computer for long periods of time can be. Just trying to stay focused on the tasks you are doing can be a major challenge.

So what causes computer fatigue syndrome? Aside from the physical aches and pains of the syndrome which can be caused from ergonomic problems, the big culprit is the electromagnetic pollution emitted from computers, especially computer monitors.

We are all exposed to negative energies not only from electromagnetic fields in computers, appliances, cell phones, power lines, etc., but also from the earth (radiation of underground water, storm or sewage pipes, caves or mineral bodies).

These energies have a negative affect on your body and sap your strength as you work causing you to be less and less productive and to feel like it's hard to stay focused on the task at hand.

The electromagnetic pollution combined with the glare from looking at a computer monitor screen especially contributes to the tired, burning itchy eyes and headaches that many of us experience after being on the computer for awhile.

The most important thing you can do to deal with this is to counteract the source of the problem in the first place which is the electromagnetic fields being produced by the computer.

And surprisingly this is reliably easy and affordable to do. I have been able to alleviate these symptoms which used to have a severe affect on me with some very simple solutions.

It's a common source of frustration for too many people; the slow computer. In many cases the thing will freeze up entirely, leaving you stranded in an electronic limbo. Thankfully there are some common causes for the freezing and slowdowns afflicting many computers and their frazzled owners. Here are some of the most common causes and some ways you can do about them.

Slow computer cause # 1 – Insufficient memory (RAM).

A lack of RAM will affect your computer the most when you are running multiple applications simultaneously. That's a fairly common occurrence these days. Think about how many times you run multiple apps at the same time. It's not tough. In fact, you're probably doing it now. In fact, it would be pretty difficult to run one at a time for most people.

Now that many computers ship with 1GB of memory or greater you may think that having computers slow down due to insufficient memory would be a thing of the past, but thanks to Microsoft's new Vista OS, we may actually see it continue or even increase. It looks like Vista has a prodigious appetite for RAM. For all but Vista Home Basic edition, Microsoft recommends at least 1GB, but you do well to double that, and bring 2GB to the party.

Slow computer cause # 2 – Spyware and adware

These sometimes malicious applications get on your PCs in all different ways, from legitimate applications installing them for tracking marketing data, to key loggers and other programs used to steal your passwords, account numbers, and other sensitive data. The bottom line is, the stuff is dangerous and slows down your computer. Even the stuff that's not malicious can easily be a culprit. It takes up valuable hard drive space and eats up clock cycles you could use for other things.

Slow computer cause # 3 – Viruses and worms

Hopefully you have a good antivirus application that's updated regularly. That will nip most virus problems in the bud, but it's still possible to get a virus. In fact, even if take all standard precautions, such as not opening unrecognized email or attachments, etc., you could still get one. If you're lucky, these malicious applications will only slow you machine down, in many cases, it will do that and much more, such as data corruption or deletion.

Slow computer cause # 4 Too much stuff going on in there.

You may just plain be asking too much of the old girl, or you may have to structure your start menu so apps you do not use al the time are not started automatically. That can not only impact your computer's speed as you're using it, but dramatically lengthen its startup time.

Slow computer cause # 5 – Registry errors

These are one of the most common causes of slowdowns and crashes experienced by most users. Registry problems can also make your computer take a longer time to start up. The registry is where, on a Windows machine, all the important settings and other information is stored that the computer and the applications use to run. It's actually a database that's created by the system itself.

As you constantly add and remove programs, it creates problems in the registry. When most applications are installed they put new entries in the registry that's used to run the application. One of the most common problems occurs when entries in the database called registry keys are missing or corrupted. These keys contain information that's sorted as either computer or user specific. This enables the machine to support multiple users and applications simultaniously, so it's easy to see how important the registry is. Incorrectly uninstalling an application is one of the most common ways a registry entry gets corrupt or deleted.

Thankfully it's not too difficult to find and repair Windows registry problems. There are applications available that will do it for you, or you can try to do it yourself if you're especially well versed in Windows. If take that path however, be careful, as a mistake here can really cost you.

These common causes of a slow computer are, in most cases, easily fixed, either through a little tweaking with your machine, or with a specific application designed to solve the problem.

Many frustrated users addicted to video streaming ask this question. Although the sudden slowdown of the giant video site occurs sometimes at the user side, people are clueless what could be the cause of this problem. It is understood no body wants to wait long for videos to load and then watch them especially if the videos are longer and are in multiple parts. Faster streaming is the need of every internet user. If YouTube runs slow sometimes then there are certainly some reasons behind that. Most people are not sure what to do in such a situation and make the videos load faster in YouTube.

Before I share the guidelines to deal with this speed slowdown I would invite you to think of the reasons which result in YouTube errors such as sluggish streaming, flash crashing in YouTube and other YouTube videos errors. There are two major reasons which result in these annoyances. One is the problem at the user end that includes PC speed, Internet speed, PC Windows errors, PC programs conflict such as Flash issues, while the second reason may be caused by the server or external internet traffic load. Although the web site is very effectively maintained there appear some troubles sometimes. This, however, is not a big issue as we all trust the services provided by such a user friendly web site. The issue becomes serious when video errors and slow speed becomes a routine. This has to be something to do with the personal computer one is using.

Here I am outlining some tips that will help you to make YouTube faster for you:

* Start from repairing your Windows registry and fixing your windows errors that become the cause of many browser and applications errors causing a conflict situation.
* Test your computer for viruses and spyware.
* Run SpeedTest to test wherever you have sufficient bandwidth available to smoothly play YouTube videos without causing the site to run slower.
* Disconnect your internet and then reconnect it to know why YouTube is slow and if it is because of the poor internet at your side.
* Disable ads through some of the browser plug in that will allow you to run few underground services while you are playing videos online.
* Try to change your flash player version. Although the YouTube has started to stream videos through a new technology there is still a large number of web sites using the flash platform. So it is a nice idea to try to change the flash player version to play videos without crashes and error messages.
* Try to change your browser. One good browser to play YouTube videos is Chrome. If you have not tried that go for it. Also contact your ISP provider if they are limiting your bandwidth at specific durations of the day.
* Also recommended that you do the following steps if the YouTube is slow due to DNS related settings:

Click start> settings> control panel> network connections> Local Area Connection / Your default Internet connection> properties> Internet Protocol TCP / IP> properties> check the option "use the following DNS server address" and use this address: Preferred DNS Server: 208.67.222.222 Alternate DNS Server: 208.67.222.220

Most computers come with warranties, but when that warranty runs out, it is a good idea to have a company that you trust readily available to assist you with any computer service you need. Even with a company on hand to call, it is important to know the basics about computer repair so you are not hit with a large repair bill that may cost as much as a new computer!

Small repairs should be simple to solve and not need the expertise of a computer service company. Often times, you can find solutions to your problems by simply searching the Internet. Most computers also come with help options on the software that is installed. Going through these steps can normally fix the problem you are having without the need for a repair company.

Going through these steps will not always be the solution to your problem. There will be times you will need computer service to fix the issue at hand. If you are lucky, and your computer is still under its warranty period, you can contact the manufacturer to assist with any problems you are experiencing. If it is out of warranty, and you did not purchase the extended warranty, you will need to rely on a service company. Often times, you can contact the manufacturer directly even after the warranty period and they will be able to assist at much less than a cost than independent computer service companies.

Before deciding to use a computer service company, you will want to weigh the cost. Having a service come in to repair you computer may be costly. You will have to decide if the costs of having them repair your computer is worth it. If you are a business owner, it may be. Losing the use of even one computer at a business could be detrimental to the production of the company so the cost of repairing the computer would be worth it.

Once your warranty expires, and you see the need for computer service you will need to decide which route you want to take with the company you chose. Many companies offer annual contracts for maintenance on your computer. You would pay an annual fee, but know that you can contact them throughout the year and they will assist you with any problems you have. Another option is to pay each time your computer has a problem.

At most times, this is the best option for individual owners. Having an annual contract would be beneficial for business owners who have more than one computer. Owning multiple computers can lead to multiple problems so an annual contract would be useful. Having just one computer, you may never experience the need for computer service throughout the year so having a contract would not be necessary. You will need to weight both options yourself and decide which one would be the most beneficial for your situation.

If you are the type of person who likes to sample and remove programs from your computer very often, you are probably familiar with system crashes and you also probably badly need a registry cleaner. You should realize that it is the way you dizzily install and uninstall programs that is causing your system to get flat feet and eventually to fall on its face. Every application you load into your system gets its corresponding slot in the system registry. It fills its slot with the key-value pairs that it will need to run and continue running.

The trouble these poses for people who are restless about their applications is that those entries are deleted when the application is uninstalled. Unless you have a registry cleaner, long after a program has disappeared from your drives, those entries remain. They are not dead entries, but they are more like undead monsters that eat up your memory and overwork your cpu. They all need to be scanned when your cpu looks up key-value pairs to run a program. Registry cleaners identify and remove invalid key-value pairs and prevent system overload which can ever lead to a crash.

Registry cleaners ferret out the ghosts in the registry and delete them. Vice versa, they can also identify whether you are missing some entries in the registry. The better ones allow you to make a backup of the system before the actual scan is done so that in the event of failure causing system handicap, you may restore the original settings. That is also the reason why the better registry cleaners are safe to use often.

People who are experts at system configuration sometimes fix their registries manually but that is not an option for average users. However, some registry cleaners enable you to perform manual removal of entries. They will first present you with a list of data that can be safely deleted and the choice is yours whether to do so or not. In this way, you can keep configurations that you intend to use in the future. Another feature included in some registry cleaners is deletion of shortcuts and references in the Path variable of windows to non-persistent programs. This speeds up both your computer's performance and as well as your own.

So if your are the type of person who

1. simply has to try out every new program and are there before probably always uninstalling old ones to make room for new ones,
2. can not get your first installation right the first time (it does happen),
3. has a computer that everyone else uses in the house uses and installs programs into

Please do what is best for you and get yourself a good registry cleaner, one that allows you to backup before scanning the registry, one with which you can perform manual scanning and on which you know you can rarely. You simply have to do your comparative research on the internet. Look up prices, the features included in the software and customer product reviews. You might also want to try the free system scans offered by some registry cleaner sellers.

We all think about personal computers frequently. We use them through the day for different purposes. They're quite basically an important part of our lives like few other machines. Since we use them for almost everything we do in some way or another it's important that our pcs are safe from invasion and attack.

While we use our pcs to store personal information, critical documents and to make dealings, we are opening ourselves to the potential for having that information stolen or tampered with. Because of the design of our personal computers, it's possible for many who are considered unsuitable to have access to specific services to enter anyway.

So that you can protect against most of these unwanted visitors, there are numerous of things you can do. Essentially the most fundamental way of protecting your computer is using a firewall. Computer firewall security be able to go a long way in keeping uninvited users from info that they may use in the wrong method.

You will find 4 different types of firewall application.

Packet filter- these examine every packet that goes by means of a network and checks whether or not they comply with rules the user has laid out.

Software gateway- these use protection mechanisms on certain applications. It can be useful, but can reduce effectiveness.

Circuit-level gateway- applications protection mechanisms at the time a connection is developed and then enabled packets to move without more examination.

Proxy server- this one looks at every message that goes by means of the network plus hides the network addresses.

When you have a firewall of any sort set up, you will know what comes and goes in your network is being inspected, or at least that there's something in place ensuring that not purely anyone can hop in plus send messages that may threaten the safety of the machine and the records it contains.

Checking which computer firewall security software meets your needs or your company is not always so easy. In case you are unsure of what precisely your company wants seek the recommendation of your IT department or hire a personal computer protection consultant that can advise you on what specifically your program needs are and how to be met and the network made as secure as achievable.

If you have your firewall in place, you should make sure that it is doing its job correctly. It is possible to check its effectiveness by giving it a safety test. You'll find these free on the internet. They will check your system and provide feedback on what parts are weak and what upgrades you need to make.

Since our PCs are so essential to our everyday lives we must make sure to protect them with the proper computer firewall security. This really is the best way to make sure that any risks will be stopped in their tracks earlier than they are able to cause any damage to your personal computer.

Many medical offices rely on portable x-ray systems to help them meet the needs of patients who cannot travel to their facilities for treatment. Physicians who work in nursing homes, sports stadiums or on cruise ships will need a portable x-ray imaging medical device to help them take digital medical images for patients who are not at a home medical facility. When the portable digital x-ray machine is coupled with a PACS system loaded onto a laptop computer with a wireless Internet connection, the physician will be able to not only capture digital images, but also view them, transmit them and then store them with the help of the computer system.

A portable x-ray system that produces DICOM medical images brings all the practicality found in a full office-sized radiology suite to your off-site patients but in a compact package. Systems are available featuring CR or DR imagers, and both can be used in a portable environment. These mobile imagers are typically used with wheeled carts, making it easy to move the equipment to the patient. The weight of the equipment is much lighter than a full-sized imager, and comes in at around ninety pounds. Models are available that can fit into a mobile unit, making it much easier to pack and unpack the necessary devices to obtain the digital images that you need.

You can gain an extra level of versatility from the portable equipment when you also utilize a PACS system on a laptop personal computer. The PACS component will allow you to view, send, receive and archive the digital images that you take while away from your home office. This means that you can use the laptop as you would a workstation. The PACS will help you enhance the digital images that you take, and you can immediately send them over a secure wireless Internet connection to consulting physicians who have access to a workstation running PACS. Peripherals such as printers can also be attached to the laptop computer, allowing you to print if needed. You can also store the digital DICOM images that you take while away from the home facility on your laptop, or send them via the Internet to a secure storage archive, where they will be ready for you or other colleagues to access when needed.

A medical imaging distributor website can help you learn more about portable x-ray systems and will allow you to determine which portable x-ray imaging medical device will work best for you.

In the past few years of research on instructional technology has resulted in a clearer vision of how technology can affect teaching and learning. Today, almost every school in the United States of America uses technology as a part of teaching and learning and with each state having its own customized technology program. In most of those schools, teachers use the technology through integrated activities that are a part of their daily school curriculum. For instance, instructional technology creates an active environment in which students not only inquire, but also define problems of interest to them. Such an activity would integrate the subjects of technology, social studies, math, science, and language arts with the opportunity to create student-centered activity. Most educational technology experts agree, however, that technology should be integrated, not as a separate subject or as a once-in-a-while project, but as a tool to promote and extend student learning on a daily basis.

Today, classroom teachers may lack personal experience with technology and present an additional challenge. In order to incorporate technology-based activities and projects into their curriculum, those teachers first must find the time to learn to use the tools and understand the terminology necessary for participation in projects or activities. They must have the ability to employ technology to improve student learning as well as to further personal professional development.

Instructional technology empowers students by improving skills and concepts through multiple representations and enhanced visualization. Its benefits include increased accuracy and speed in data collection and graphing, real-time visualization, the ability to collect and analyze large volumes of data and collaboration of data collection and interpretation, and more varied presentation of results. Technology also engages students in higher-order thinking, builds strong problem-solving skills, and develops deep understanding of concepts and procedures when used appropriately.

Technology should play a critical role in academic content standards and their successful implementation. Expectations reflecting the appropriate use of technology should be woven into the standards, benchmarks and grade-level indicators. For example, the standards should include expectations for students to compute fluently using paper and pencil, technology-supported and mental methods and to use graphing calculators or computers to graph and analyze mathematical relationships. These expectations should be intended to support a curriculum rich in the use of technology rather than limit the use of technology to specific skills or grade levels. Technology makes subjects accessible to all students, including those with special needs. Options for assisting students to maximize their strengths and progress in a standards-based curriculum are expanded through the use of technology-based support and interventions. For example, specialized technologies enhance opportunities for students with physical challenges to develop and demonstrate mathematics concepts and skills. Technology influences how we work, how we play and how we live our lives. The influence technology in the classroom should have on math and science teachers’ efforts to provide every student with “the opportunity and resources to develop the language skills they need to pursue life’s goals and to participate fully as informed, productive members of society,” cannot be overestimated.

Technology provides teachers with the instructional technology tools they need to operate more efficiently and to be more responsive to the individual needs of their students. Selecting appropriate technology tools give teachers an opportunity to build students’ conceptual knowledge and connect their learning to problem found in the world. The technology tools such as Inspiration® technology, Starry Night, A WebQuest and Portaportal allow students to employ a variety of strategies such as inquiry, problem-solving, creative thinking, visual imagery, critical thinking, and hands-on activity.

Benefits of the use of these technology tools include increased accuracy and speed in data collection and graphing, real-time visualization, interactive modeling of invisible science processes and structures, the ability to collect and analyze large volumes of data, collaboration for data collection and interpretation, and more varied presentations of results.

Technology integration strategies for content instructions. Beginning in kindergarten and extending through grade 12, various technologies can be made a part of everyday teaching and learning, where, for example, the use of meter sticks, hand lenses, temperature probes and computers becomes a seamless part of what teachers and students are learning and doing. Contents teachers should use technology in ways that enable students to conduct inquiries and engage in collaborative activities. In traditional or teacher-centered approaches, computer technology is used more for drill, practice and mastery of basic skills.

The instructional strategies employed in such classrooms are teacher centered because of the way they supplement teacher-controlled activities and because the software used to provide the drill and practice is teacher selected and teacher assigned. The relevancy of technology in the lives of young learners and the capacity of technology to enhance teachers’ efficiency are helping to raise students’ achievement in new and exciting ways.

As students move through grade levels, they can engage in increasingly sophisticated hands-on, inquiry-based, personally relevant activities where they investigate, research, measure, compile and analyze information to reach conclusions, solve problems, make predictions and/or seek alternatives. They can explain how science often advances with the introduction of new technologies and how solving technological problems often results in new scientific knowledge. They should describe how new technologies often extend the current levels of scientific understanding and introduce new areas of research. They should explain why basic concepts and principles of science and technology should be a part of active debate about the economics, policies, politics and ethics of various science-related and technology-related challenges.

Students need grade-level appropriate classroom experiences, enabling them to learn and to be able to do science in an active, inquiry-based fashion where technological tools, resources, methods and processes are readily available and extensively used. As students integrate technology into learning about and doing science, emphasis should be placed on how to think through problems and projects, not just what to think.

Technological tools and resources may range from hand lenses and pendulums, to electronic balances and up-to-date online computers (with software), to methods and processes for planning and doing a project. Students can learn by observing, designing, communicating, calculating, researching, building, testing, assessing risks and benefits, and modifying structures, devices and processes – while applying their developing knowledge of science and technology.

Most students in the schools, at all age levels, might have some expertise in the use of technology, however K-12 they should recognize that science and technology are interconnected and that using technology involves assessment of the benefits, risks and costs. Students should build scientific and technological knowledge, as well as the skill required to design and construct devices. In addition, they should develop the processes to solve problems and understand that problems may be solved in several ways.

Rapid developments in the design and uses of technology, particularly in electronic tools, will change how students learn. For example, graphing calculators and computer-based tools provide powerful mechanisms for communicating, applying, and learning mathematics in the workplace, in everyday tasks, and in school mathematics. Technology, such as calculators and computers, help students learn mathematics and support effective mathematics teaching. Rather than replacing the learning of basic concepts and skills, technology can connect skills and procedures to deeper mathematical understanding. For example, geometry software allows experimentation with families of geometric objects, and graphing utilities facilitate learning about the characteristics of classes of functions.

Learning and applying mathematics requires students to become adept in using a variety of techniques and tools for computing, measuring, analyzing data and solving problems. Computers, calculators, physical models, and measuring devices are examples of the wide variety of technologies, or tools, used to teach, learn, and do mathematics. These tools complement, rather than replace, more traditional ways of doing mathematics, such as using symbols and hand-drawn diagrams.

Technology, used appropriately, helps students learn mathematics. Electronic tools, such as spreadsheets and dynamic geometry software, extend the range of problems and develop understanding of key mathematical relationships. A strong foundation in number and operation concepts and skills is required to use calculators effectively as a tool for solving problems involving computations. Appropriate uses of those and other technologies in the mathematics classroom enhance learning, support effective instruction, and impact the levels of emphasis and ways certain mathematics concepts and skills are learned. For instance, graphing calculators allow students to quickly and easily produce multiple graphs for a set of data, determine appropriate ways to display and interpret the data, and test conjectures about the impact of changes in the data.

Technology is a tool for learning and doing mathematics rather than an end in itself. As with any instructional tool or aid, it is only effective when used well. Teachers must make critical decisions about when and how to use technology to focus instruction on learning mathematics.

Should you get a desktop computer, a laptop, or a netbook? Since there are so many options out there, it can often be difficult to decide which one is right for you. However, by mirroring it down to a couple of considerations, you can easily figure out which type you should get. For starters, let's talk about the netbook. These are the extremely tiny computers that can basically fit into a backpack and you will not know that they're there. They are ideal for somebody who only very casually uses the Internet. If you occasionally send off an e-mail and liked check your Facebook every now and then, then this might be right for you. However, if you like to do other things together that, it's probably not right.

There was a time when desktop computers were the only way you could get everything done you needed to. Laptops are more of a convenience, and they did not have as many features because they were so portable. However, now they have laptops that are desktop replacements. They have just about all the same features as desktop computers. Granted, desks can be more powerful, but laptops are portable. That's really where you need to draw the line. If you need your computer to be portable, and you have to get a laptop. If you need the highest performance available, they need to get a desktop.

If what you're looking for does not hinge on one of those two deciding factors, then you can pretty much choose which one you want. You'll find ones in your price range from either side, and doubled the will to do what you want to do. The important thing is to get the computer that's good for you, whether it's a laptop, desktop, or netbook. If you do this, you'll be amazed at the results.

Computers are basically a must have in every house nowdays. This is true because of its various functionalities and purposes. Computers are used in a lot of things. People use them for their business, for communication, and for entertainment. The computer has grown into an item of great value and help not just around the business area but even at home. On the next few paragraphs of this article, we will be talking about how much a computer help at home.

Here we will be discussing some of the most important functions and roles of computers at home and a bit on the business world.

Computers for management – As of now, a lot of programs have been developed to help people keep track of different things. In business, they are various software made that are totally dedicated in providing assistance in managing things and tasks. At home, there are also available software that manages families eating habits and exercise schedules. In response to the busy lifestyles that people have nowdays, people may tend to forget their important schedules so computers can keep track on these things and can be programmed to remind us when we need to do some certain things at some times. That is how computers help us in management.

Computers for communication – With the continuous development when it comes to our technology, the internet has gained more power over the past few years. As of now, communication through internet has been a very much favored development. The increase in internet messengers that can provide free online chatting and video calls are not just being used by big shot companies as a main communication device but even to families who are separated with each other because of work or school. People can talk as much as they want and would not even cost them a single dime. All they need is their computer and an internet connection and they are good to go.

Computers for entertainment – Computers have a lot of add on hardware that you can put as additional options for better performance or added task capabilities. Putting DVD Roms can turn a PC into a DVD player. Connect a 6 channel subwoofer system and you have the experience of watching movies in the cinema. Now, that is home theater. The effects of game programs playable in computers are also a great experience to have. The visuals and game plays are great and entertaining.

These are just a few things about what the computer can do to us and our families. Computers nowdays are like one-stop shop for total entertainment and supply of needs.

Physicians often find that they can provide the best patient care when they have access to a portable x-ray system. Patients who are not mobile, those in nursing homes, as well as those in other environments such as athletes in a sports arena would be common examples where portable x-ray machines are needed. Happily, there are several options for cost-effective and easy-to-transport portable digital x-ray systems for your use.

A portable system offers many of the same features as an in-office x-ray system. A better portable x-ray system will allow for the distribution of digital medical images when you are out of the home office environment. Portable x-ray machines are typically CR, or computed radiography, systems that utilize erasable cassettes and phosphor plates to capture the patient medical images. Several systems allow you to easily store and then recall commonly used settings, saving you time. When used in conjunction with a laptop computer with wireless Internet access, the system can also function as a clinical workstation as you would have in your home medical office. With digital image capture made possible with a portable system, you will also have the ability to archive the digital images you take out in the field, or quickly quickly send them back to your home medical facility for further diagnoses. Portable systems also last a long time, even in strenuous field conditions. They are made with strong wheel and metal components that will end for many seasons. Many systems also come with different sizes of wheels, so that you have the option of larger wheels to cover long distances faster, or smaller wheels for easy use in tight quarters.

The small size and portability of these x-ray devices make them perfectly suitable for in-field digital radiography image capture. You will appreciate the ease with which you can move these systems around, even in tight quarters, and you will be pleased at how little room it takes up in your vehicle. Weighing in at only eighty-eight to ninety-seven pounds and usually placed on a wheeled carrier, a portable x-ray system will not cause you physical stress to move it about. Many of the carriers also fold up, saving even more space in your transport vehicle.

If you are a mobile medical service provider, you can offer better patient care with a fully functional and affordable portable digital x-ray system at your disposal.

Top 5 Grand Theft Auto V Characters.

5. Lester Crest

Lester is the mastermind behind all the heists and despite he suffers from a wasting disease which has gradually worn down his motor skills during his life and left him wheelchair-bound he is still no less of a threat. He excels best behind his computer screen and is not a person you would like to piss off.

At an unknown point in time, Lester met and became associated with Michael Townley and Trevor Philips, becoming a regular member of their hest crews since the start of their partnership.

4. Lamar Davis

Lamar is the best friend of Franklin Clinton they both went to Davis High School together when they were teenagers. Occasionally, the two men became involved in crime. Now going about stealing (or "repo-ing") cars for the dealership where they work. Lamar always has something intelligent to say, even if he does not have the eloquence to really say it, and he shows that there is more to a small time gangster than meets the eye.

Fun Fact: Lamar was originally supposed to be the character that Franklin ended up being but due to a last minute decision by Rockstar his role was altered.

3. Franklin Clinton

Franklin is a small time gangster, working for a crooked guy who wants him to boost cars for a living. Franklin is the first playable character in GTA V (discounting the prologue) and is our first introduction to the sprawling world of Los Santos.

Franklin was born in South Los Santos in 1988. Following his mother's death, Franklin moved in with his grandparents. Despite being constantly spoiled by his grandmother, Franklin had decided to take on the role of a street hustler. One of his first jobs was selling cigarettes with Bradshaw however, it is not until Franklin jacks Michael's son's car that he is promoted into the criminal world of high risk, high reward.

2. Micheal De Santa / Townley

Michael Townley used to be part of a big time gang, pulling off bank heists and getting into ferocious shoot-outs. After he is shot by the police, however, he decides to take the way out; witness protection in exchange for information.

Michael is a great character to balance the three protagonist structure. He strikes a balance between Franklin's cool, collected attitude and Trevor's crazy. Michael can be as reasonable as the next guy, but when he's in a bad mood, he can almost be as manic as his old partner. Michael is about as far away from the stereotypical GTA protagonist as you could get, and it seems rather fresh to start off the game as a success this time round.

1. Trevor Philips

Who else could it have been? Rockstar's newest psychopath is different because he's also a protagonist. Trevor Phillips is wild and unhinged. His company, Trevor Phillips Industries, seems to only have two things on its business plan – kill everyone and sell some meth. As the story progresses, Trevor carries out torture, brutally murderers people, takes a man's wife host and continues his one man rampage.
Trevor is an unbelievably complex character, and will go down in GTA history as one of the wildest characters ever.

"This is my life's work. I mean since I was a little kid II dreamt big." Y'Know, I've always wanted to be an international drug dealer and … weapons trader. " – TREVOR PHILIPS

Ever since the computer came out it has continuously been changing the way the world runs and will certainly keep evolving. The personal computer was something that made a big difference in the sectors of commerce and industry and today these two sectors of the world can not function without the help of the computer. The use of desktop computers helped better communication between parties but the need of a portable computer came a lot sooner than expected. The laptop or notebook computer allows a person to take a whole lot of information wherever he goes and transmit that information to anyplace in the world within seconds with the help of the Internet. This is the advantage of having a portable computer.

There are a lot of types of portable computers that are available in the market today which vary a little in size, technical specifications (features) and purpose. Portable computers can be classified into three types: desktop replacements, laptops and subnotebooks. The desktop replacements have just about the same features of a desktop computer and the display is more than 15 ", the standard laptops can range from about 13" to 15 "and the subnotebooks are small size computers that have a display screen of 12 inches and below.

People say that there is a difference between notebooks and laptops, but the two terms have been jumbled up and it makes no difference anyways and these have become the two general terms used for portable computers. But all this does not matter when you are going to buy your first laptop, or should I say notebook computer. What matters is what you are going to use the computer for and the places you are going to take it.

Buying the right computer depends on you and not the brand of the computer you are going to buy. The right computer should have all the technical specifications that you want and more importantly, should be priced within your budget. If you are a frequent traveler and you buy a laptop that has a 17 inch display and great specs you are making the wrong decision, and it will be better to buy one that is a lot lighter and smaller.

While buying a notebook computer you must write down a list of things that you want in your notebook computer and also the price you are willing to pay for it. The memory of the hard disk, the processor you want, the RAM you want to get and the size of the display screen are the important things you must include on the list.

There are times when you will come across a good looking, expensive laptop that is above your budget and you really want to buy, but its better you do not, especially if it does not have the features you want it to. You must always look for the best laptop which will suit your criteria so that you do not regret later. Buying the right laptop involves a lot of research, so look at every possible kind of laptop available in the market to get the best one.

Having a dirty work space or even worse a dirty computer can make you sick very fast. Due to all the people touching your computer it will get very dirty very fast. There are many reasons why you can keep your computer clean but here are just a few important ones to remember.

1. Cleaning makes your computer healthy, so allowing it to stay up and running for a longer time. The growing cost and expenses of computers these days will surely make you broke real fast if you do not have one computer for at least 3 years or so. If you work for a business or own one that deals with computers then you should know how keeping your computer running is very important.

2. Keeping your computer clean is also great for saving up to 65% on computer repairs. Since that most computer corruption comes from dirt and other unknown objects that are unsanitary will cause broken computer systems.

3. If you happen to have a lot of dust in the inside of your computer it can block the fan and then create overheating, which can be the main cause of slow running computers. Take the time to clean the inside and do yourself a favor.

4. Believe it or not it dirt gets in the wrong places it puts all your computer data at risk. If you run a business on computers that means no more data that you ever have used in the past.

5. Not only is cleaning better for the performance of your computer it helps stop the spread of sickness with out failure.

Remember these words and you'll have a safe and clean working environment in no time.

Working on Microsoft Word is productive yet a little risky if care is not taken to protect it from crashes and speed slow downs. You often experience Microsoft Word slow in loading files. This is very frustrating and there seems no obvious fix. However, you can optimize the performance of your computer programs by following the guidelines in this article.

When you downloaded the program did you install the program properly? Sometimes the important files are not installed which makes the Word to crash and run slower. It is important you try to repair your program through the software DVD owned by you.

Figure out wherever your computer is equipped with the enough resources to bear the load of programs running on it. For instance the old PCs are found to perform poorly if they are loaded with the heavy versions of the softwares. However, for old computers the only solution to speed up computer is to properly maintain the system and to clean it from registry errors and optimize the speed through a best available registry cleaner software.

There are thousands of registry keys stored in the Windows registry database. These keys are very important to keep your programs running well. Similarly the registry keys also define the settings of different programs and a minor change in these settings can wreck a havoc on your system. It should be made a habit to clean Windows registry periodically to let the corrupted registry out of computer. Sometimes the Microsoft Word errors are linked to the Windows settings. You should always take care to protect your Windows and fix registry to preserve important settings.

Information Technology continues to be a growing industry, despite the fact that the face of Information Technology is constantly changing. In place of the formal IT department, the growing trend is for companies to leverage providers who specialize in IT support.

IT support falls into several main categories: on-site computer maintenance, network administration, network hosting through cloud technology, or voice-over IP telephone systems.

On-site Computer Repair

Perhaps the first of the areas where IT computer support established itself as an industry, on-site computer repair is perhaps the most basic aspect of tech support. When looking for a computer hardware service, it is critical that each of their technicians have the proper hardware repair certificates and an appropriate level of knowledge to repair your computers in an efficient manner. These services may have a minimum call price or charge an hourly rate. Either way, you want to make sure you are using the best technician possible for the price.

Network Administration

Many companies now rely on network support providers to meet all their networking needs. Instead of having to monitor the size of the team and guess requirements in order to properly support their network, by outsourcing the daily network support, it allows business management to focus on their core business instead of the information backbone. The pantheon of remote network utilities makes everything but on-site hardware fixes an easy remote repair.

Network Hosting through Cloud Computing

The next step in ensuring proper IT support is the growth of off-site computing centers. Considered the next big change in the Information Technology landscape, Cloud Computing allows both the hardware and software portions of the network administration to happen remotely. High-speed connections, cheap data storage and the ability to flex the size and capabilities of the available computing system actually real-time are just a few of the advantages to Cloud Computing.

Voice-Over-IP

This telephone technology is becoming the standard in businesses today, as well as in the residential market. This takes telephone installation and repair out of the hands of the old-school lineman and into the hands of IT professional.

Whether it is in a business or a home, there are needs for IT computer support that vendors are waiting to service.

Windows registry issues can be a worrisome one especially if you are not skillful at resolving computer related issues. You can fix problems with the database of your computer (the registry) manually, but it is best and safe to use software specifically designed for this purpose – the registry cleaner.

Steps to take in Fixing your Computer Registry

The first thing to do is to ascertain that the problem with your PC is a Windows registry issue. The signs for a faulty registry include slowness, freezes, error messages, prolonged time while opening applications and general under-performance of the PC. If this is the case with your PC, then you can proceed with the below guidelines

• Click on registry to open the registry cleaner and ensure that the boxes under "registry cleaner" are all checked.

• Click "Scan" to find errors and other invalid entries on your computer system. Then, watch as the progress bar reads off and get to 100 percent. The errors located by the software will be displayed.

• Next, locate the button for "remove" or "repair" as the case may be, to either remove an error or repair a damaged file.

• Prior to removing or repairing, a dialogue box will be displayed to ask for backing up of changes to the registry; the backup features will make a copy of your registry in case of any temporary error, so that you can restore your system to its former state before the scanning and cleaning.

• At the completion of the scanning and cleaning, just click close to finish the process. You can now restart your system to see the effect of the cleaning on your PC. If the software was effective enough, your PC's speed will skyrocket, freezes will cease and the overall performance of your PC will be greatly improved.

Registry cleaner is the best tool for handling issues related to the Windows registry of your PC. However, you have to be careful to choose risk-free and highly effective software for this purpose. You also need to look out for certain features that characterize a good registry cleaner.

Have you been listening things in the news lately about treadmill desks but can not really imagine how they work? The concept sounds strange at first but is actually quite simple. The biggest challenge in even considering a treadmill desk is the mental shift required.

Let me pose a few questions:

1. Have you been trying to think of ways to add more activity into your day?
2. Do you have physical issues (like a sore back or shoulders or hip) from sitting at a desk all day?
3. Do you find that your post is not good (shoulders roled forward, head hanging forward)?
4. Do you have a few pounds you'd like to drop?
5. Do you exercise regularly but still find yourself feeling blah at your desk job?
6. Do you suffer from the dreaded "post-lunch dip" – that mid-afternoon feeling of fatigue?

A treadmill desk can offer a viable solution to all of the above. There are now a number of treadmill desks that are manufactured all-of-a-piece, and there are ways to easily set up a treadmill desk using a standard treadmill. Different approaches are right for different people and different budgets.

Treadmill desk manufacturers include companies like Steelcase, TrekDesk and Lifespan Fitness. Steelcase is a 100-year old office furniture company that consulted with James A. Levine, MD, of the Mayo Clinic to design a state of the art treadmill desk.

Dr. Levine advocates use of a treadmill desk to combat obesity and he's done a lot of research on the topic. There are a number of articles available online that will offer you scientific evidence that use of a treadmill desk can be very positive, but it just stands to reason, does not it? Our bodies were made to move – to walk, to run, to stay active. Human anatomy did not evolve to just sit, and the pain we feel in our bodies when we sit too much is evidence of this. The computer revolution of the last generation has transformed many things about our lives in a positive way, but unfortunately, sitting all day is not one of them.

The result of Dr. Levine's input and Steelcase's masterful design is the Walkstation , a really attractive, contemporary desk attached to a treadmill. The company makes several models of treadmill and standing desks that are well-designed, the result of research on ergonomics and office viability.

Trekdesk is another maker of treadmill desks. This company makes just the desk component – the piece that sits over an existing treadmill. They have recently reduced the cost of their desk to less than $ 500. When I was doing research for my own treadmill desk, I corresponded with the customer service department at Trekdesk and was impressed by their friendship and professionalism.

Lifespan Fitness is another company that makes a variety of treadmill desks to fit different needs and budgets. This company also sells a "standing desk bike" for pedaling in place at your standing desk. An interesting idea! This would work well for someone who prefers pedaling to walking and who already has a standing desk.

Due to budget constraints, I had to take a different approach, but if I had the money, I'd buy a treadmill desk from one of the above companies. They are forging a new trail for us folks traditionally stuck sitting all day!

My treadmill desk is a very simple set-up. I purchased a Nordic Track machine – a moderately priced model that tested as sturdy and quiet. Sears offers a number of treadmills and has a lot of them set up so you can try them in the store, which I found very helpful. I was able to purchase the treadmill along with a three year extended warranty, which seemed like a good idea since I was planning to use the treadmill a lot. Other stores, such as Dick's Sporting Goods, also have treadmills set up to test drive. I recommend you try a few and compare. Remember that using a treadmill for work is quite different from using a treadmill for aerobic exercise. You will be walking slowly – about 1.5 miles per hour – so you do not really need a fancy machine with lots of bells and whistles (except of course you do intend to use it for aerobic exercise sometimes, or someone else in the household will use it that way). Think carefully about how you and your family will use the treadmill before making your purchase.

I looked for a treadmill with arm rests parallel to the floor, to offer supports for my "desk". The desk is really just a board that sits on top of the treadmill arms. I attached two platforms to the main board to create elevated shelves for my laptop computer and my large, extra monitor. The desk board serves as a shelf for the separate keyboard and mouse pad I use. Unsure how secure the desk board would be, I initially used large clamps to hold the board in place, but I've stopped using those – they just do not seem necessary. The whole set-up probably cost me $ 20 and a couple of days of measuring, banging boards together and a small amount of cursing. I ended up with something that has now served me really well for over a year. I love it.

Many people wonder if they could actually work on a treadmill – that is, type, read the computer screen, concentrate, etc., all while walking. Dr. Levine's research has shown that some people require several hours, or even days, of practice to get the hang of the treadmill desk, but that most folks do adjust pretty quickly. I had no problem adjusting and was able to type, read, talk on the phone, etc., immediately. Concentration is no problem. In fact, I concentrate much better when I'm walking on my treadmill. My mind is sharper and I definitely avoid the afternoon blahs, so my employer is getting a much better worker as a result of my treadmill desk. My prediction is that, in a few years, treadmill desks will be routine and sitting all day will be considered the strange thing!

When you are experiencing a slow down in your computers speed and performance, any useful information will surely be welcomed to bring your computer back to its usual speed. Here are some ways that will speed up your computer.

1. Always delete unused programs or unnecessary files in your hard drive. A clogged hard drive will cause a tremendous slow down in your computer. This is also applicable for browser cache, temporary internet files and a lot more. It is very important to delete them on a regular basis.

You can download free versions of freeware programs that will help in removing all these files completely in your hard drive. When your hard drives have more space then it will function smoothly and on a fast manner. there is a free program called "revo uninstaller" that removes programs completely and does not leave anything behind.

2. If you have been experiencing slower start us then you need to clear or disable useless start programs in your computer. most people are clueless about how to do this procedure. So to help most of those who are unaware of this very important procedure, here is a very simple guide. In your computer click on the start menu then on the run command and type in "msconfig". By doing this you will be shown the programs that run automatically in your start up on the start up tab.

What most people do not notice is that when they install new programs, these programs tend to appear in the start up processes. They run without you being aware. Remember that you do not need all your programs up and running in your start up. You can just run a program only when you want to use them. You are not going to use all programs at the same time. To speed up your start up process disable or remove unnecessary programs and stop them starting with windows by unticking them from the start up tab in msconfig.

3. It is very important that you defragment your hard drive at least once a month. Any fragmented file will cause inefficiency in your computers speed. Disorganized hard drives will make it more difficult for your computer to process important programs quickly. Since windows computers have a built in defragmenter utility you can use it to your advantage. The process can be time consuming depending on how big your hard drive is but will create dramatic changes in your computers speed.

4. Use anti-virus and anti-spyware programs to protect your computer from any malicious threats. Viruses, malware, adware and spyware consume a lot of your systems resources and cause it to slow down. By protecting your computer in this way you can speed up your computer quickly.

Businessmen, students, professionals and other regular people use a computer constantly. When you are using a slow computer it slows down what you are doing as well. To solve this problem, here are easy tips how you can speed up a slow computer in minutes.

Tip # 1

Remove unnecessary files and programs that you do not use anymore. The more disk space you have the faster your computer can process. You can also remove programs that you use or you can find other programs that have a smaller size than the recent program you are using.

Tip # 2

Defragment your hard drive to arrange and fix your files and folders. When using your computer, some of the files and folders in your hard drive are misplaced. Defragmenting your hard drive will make it easier for your processor to process applications because the files and folders in your hard drive are already arranged.

Tip # 3

Upgrade or free some RAM (Random Access Memory). Low RAM will be the first cause of the slowing down of your computer. There are certain applications and programs that require high RAM. If you think that your RAM is too small for the programs you have it is better to upgrade it or remove some programs to speed up a slow computer.

Tip # 4

Be sure that your PC is protected with anti-virus software. Your computer may be slowing down because it is infected with viruses, malware, adware or spyware. To solve this problem you can use an anti-virus protection. It will block viruses and other harmful files and it can also scan and delete viruses if ever there are some that escaped its protection.

Tip # 5

If the problem with viruses and other harmful files are already dealable with you should also check on the registry settings for your programs and applications. It is important that you check it out because it will not only slow down your computer but it can also damage your files. You can check and fix the registry of your file with the help of registry cleaners which you can download and install for free and speed up a slow computer.

The World Wide Web has opened a whole new world of opportunity to those who need or want to learn English. Instead of being required to go to regular classes and study with a teacher in a traditional setting, which many do not have time to do, those who want to learn English can now do so from the comfort of their own homes on the computer.

Benefits of Learning English with the Computer

Whether you use an online format or a computer software program to learn English, utilizing technology carries many benefits. First, you are able to learn at your own pace. If you take English in a traditional classroom, you are forced to learn at the pace of the rest of the class. If you are more proficient than the average student, you will be held back. On the other hand, if you are learning more slowly than your classmates, you may be left behind. Technological resources allow you to learn as quickly or slowly as you want, giving you the chance to spend extra time on the areas where you need more help.

Another benefit to learning through technology, especially online courses, is the fact that you can learn no matter where you are. As long as you have an Internet connection, and with WiFi technology this is becoming more and more available available, you can log on to your class and do a lesson or two. If you are required to travel frequently for your job, you can still use the computer to improve your English skills. This is not possible if you enroll in a traditional English class, as you will be required to be present at your scheduled class time.

Learning English Online Works

You are probably wondering if learning English online is going to sacrifice the quality of your speaking and reading ability. If you choose a good online program it will not. The best online English courses give you the chance to practice writing and speaking English. You may need a microphone for your computer in order to speak, or the listening ear of a friend, but you will learn the language well.

Choosing a Program

The key to your success in learning English using the computer is choosing the right program or course. Choose a program that focuses on basic vocabulary first, and then teachers you English through conversation, either written or spoken. Grammar rules are important as well, but if your goal is to be able to converse fluently, you need a program that jumps right into conversation after teaching you some basic words. Grammar rules can be learned after some conversation has been mastered.

Ideally, choose a program taught by native English speakers. Be sure to choose a course that has a listening component. You will need to be able to hear the different sounds of the language repeatedly in order to learn to speak them. This is one way in which learning English with the computer is helpful, because you can replay sentences over and over until you have mastered them.

Other Online Resources

The Internet also gives you the chance to practice reading and writing in English. Since 80 percent of all websites are in English, you can read as much of the language as you want after you have gained a basic understanding of common phrases and vocabulary. In addition to this, chat rooms, online forums, and discussion groups give you the chance to practice writing in English, with the opportunity to get some feedback on your grammar and spelling. Additionally, there are many websites where you can download worksheets and even games that give you the ability to practice your vocabulary skills. The Internet is a treasure trove for people who are trying to learn English, so stop making excuses, get online, and start learning!

Both are tools used to measure horizontal and vertical angles during surveying and engineering projects. Each have particular pros and cons which can be utilized in various situations. In general, it will depend on the time, money, man power, and expertise you have available when deciding on the right tool for your job.

Although theodolites have been used for hundreds of years, the main operation of these tools remains the same. A theodolite consists of a moveable telescope mounted between a vertical and horizontal axes. The angle of each axes can be measured with fairly accurate precision as long as the operator has sufficient knowledge of the tool’s use and basic trigonometry. However, the use of a theodolite generally requires the help of at least one other person besides the main operator to help measure and align angles. When precision counts, it is imperative that both operators are properly trained and understand all of the elements of gathering data; this may include leveling the tripod/theodolite and measuring stake, as well as aligning the stake and measuring line to gather accurate data, and finally use mathematical and graphical skills to generate the appropriate output.

The benefits of a total station will outweigh the downsides, in most cases, because of its all-inclusive features and digital integration. These tools integrates theodolite functions in order to measure angles and distance with an EDM (electronic distance meter). They also use a system of prisms and lasers to develop digital readings of all the measurements during your job. All of the information gathered with the total station is stored in an external computer where data can be manipulated and added to CAD programs. Robotic total stations are available that allow the operator to work alone with the use of a remote control.

A total station is generally superior to a theodolite because of its digital integration and precision. However, total stations are much more expensive and require not only surveying training, but specific product and software training as well. When completing surveying jobs that span large distances, especially over treacherous terrain, a total station will provide the most reliable and accurate results. For simple plots of smaller areas, a theodolite is sufficient. Before you purchase either tool, ensure it comes with the necessary accessories you’ll need on the job. For a theodolite you will want a measuring stake and steel tape, a tripod, as well as grid paper and a pencil to record the data. In most cases, a total station will come with all the necessary accessories you need, however, some may not so always double check!

The term “electronic keyboard” refers to any instrument that produces sound by the pressing or striking of keys, and uses electricity, in some way, to facilitate the creation of that sound. The use of an electronic keyboard to produce music follows an inevitable evolutionary line from the very first musical keyboard instruments, the pipe organ, clavichord, and harpsichord. The pipe organ is the oldest of these, initially developed by the Romans in the 3rd century B.C., and called the hydraulis. The hydraulis produced sound by forcing air through reed pipes, and was powered by means of a manual water pump or a natural water source such as a waterfall.

From it’s first manifestation in ancient Rome until the 14th century, the organ remained the only keyboard instrument. It often did not feature a keyboard at all, instead utilizing large levers or buttons that were operated by using the whole hand.

The subsequent appearance of the clavichord and harpsichord in the 1300’s was accelerated by the standardization of the 12-tone keyboard of white natural keys and black sharp/flat keys found in all keyboard instruments of today. The popularity of the clavichord and harpsichord was eventually eclipsed by the development and widespread adoption of the piano in the 18th century. The piano was a revolutionary advancement in acoustic musical keyboards because a pianist could vary the volume (or dynamics) of the sound the instrument produced by varying the force with which each key was struck.

The emergence of electronic sound technology in the 18th century was the next essential step in the development of the modern electronic keyboard. The first electrified musical instrument was thought to be the Denis d’or (built by Vaclav Prokop Dovis), dating from about 1753. This was shortly followed by the “clavecin electrique” invented by Jean Baptiste Thillaie de Laborde around 1760. The former instrument consisted of over 700 strings temporarily electrified to enhance their sonic qualities. The later was a keyboard instrument featuring plectra, or picks, that were activated electrically.

While being electrified, neither the Denis d’or or the clavecin used electricity as a sound source. In 1876, Elisha Gray invented such an instrument called the “musical telegraph.,” which was, essentially, the very first analog electronic synthesizer. Gray discovered that he could control sound from a self-vibrating electromagnetic circuit, and so invented a basic single note oscillator. His musical telegraph created sounds from the electromagnetic oscillation of steel reeds and transmitted them over a telephone line. Grey went on to incorporate a simple loudspeaker into his later models which consisted of a diaphragm vibrating in a magnetic field, making the tone oscillator audible.

Lee De Forrest, the self-styled “Father Of Radio,” was the next major contributor to the development of the electronic keyboard. In 1906 he invented the triode electronic valve or “audion valve.” The audion valve was the first thermionic valve or “vacuum tube,” and De Forrest built the first vacuum tube instrument, the “Audion Piano,” in 1915. The vacuum tube became an essential component of electronic instruments for the next 50 years until the emergence and widespread adoption of transistor technology.

The decade of the 1920’s brought a wealth of new electronic instruments onto the scene including the Theremin, the Ondes Martenot, and the Trautonium.

The next major breakthrough in the history of electronic keyboards came in 1935 with the introduction of the Hammond Organ. The Hammond was the first electronic instrument capable of producing polyphonic sounds, and remained so until the invention of the Chamberlin Music Maker, and the Mellotron in the late 1940’s and early 1950’s. The Chamberlin and the Mellotron were the first ever sample-playback keyboards intended for making music.

The electronic piano made it’s first appearance in the 1940’s with the “Pre-Piano” by Rhodes (later Fender Rhodes). This was a three and a half octave instrument made from 1946 until 1948 that came equipped with self-amplification. In 1955 the Wurlitzer Company debuted their first electric piano, “The 100.”

The rise of music synthesizers in the 1960’s gave a powerful push to the evolution of the electronic musical keyboards we have today. The first synthesizers were extremely large, unwieldy machines used only in recording studios. The technological advancements and proliferation of miniaturized solid state components soon allowed the production of synthesizers that were self-contained, portable instruments capable of being used in live performances.

This began in 1964 when Bob Moog produced his “Moog Synthesizer.” Lacking a keyboard, the Moog Synthesizer was not truly an electronic keyboard. Then, in 1970, Moog debuted his “Minimoog,” a non-modular synthesizer with a built-in keyboard, and this instrument further standardized the design of electronic musical keyboards.

Most early analog synthesizers, such as the Minimoog and the Roland SH-100, were monophonic, capable of producing only one tone at a time. A few, such as the EML 101, ARP Odyssey, and the Moog Sonic Six, could produce two different tones at once when two keys were pressed. True polyphony (the production of multiple simultaneous tones which allow for the playing of chords) was only obtainable, at first, using electronic organ designs. There were a number of electronic keyboards produced which combined organ circuits with synthesizer processing. These included Moog’s Polymoog, Opus 3, and the ARP Omni.

By 1976, additional design advancements had allowed the appearance of polyphonic synthesizers such as the Oberheim Four-Voice, and the Yamaha series CS-50, CS-60, and CS-80. The first truly practical polyphonic synth, introduced in 1977, was the Sequential Circuits Prophet-5. This instrument was the first to use a microprocessor as a controller, and also allowed all knob settings to be saved in computer memory and recalled by simply pushing a button. The Prophet-5’s design soon became the new standard in the electronic keyboards industry.

The adoption of Musical Instrumental Digital Interface (MIDI) as the standard for digital code transmission (allowing electronic keyboards to be connected into computers and other devices for input and programming), and the ongoing digital technological revolution have produced tremendous advancements in all aspects of electronic keyboard design, construction, function, sound quality, and cost. Today’s manufactures, such as Casio, Yamaha, Korg, Rolland, and Kurzweil, are now producing an abundance of well-built, lightweight, versatile, great sounding, and affordable electronic keyboard musical instruments and will continue to do so well into the foreseeable future.

It can not be denied that most people depend on computers and technological devices to make their works and lives easier. Others even earn money by creating and advancing these models for greater efficiency and reliability. Work is always a part of a person's life. It is where he gets what he needs to survive; however, work can take one's life and environment when it is not properly done. An example would be disposing too much waste that can harm a person's health and even the healthy cycle of nature. So why do people rely on technology when it can either uplift or ruin a person's existence? Maybe the answer lies on how one deal with the advancement of tools, like the computer.

A computer is designed to do tasks that are sometimes tedious when done manually like typing, drawing, creating presentations, etc. It has different parts that are made in dissimilar ways to construct a more advanced one for diverse types of works. Some common parts of a computer are speakers, keyboards, monitors, and printers. Printers are believed to have hazardous components because of the ink or toner cartridges installed in them. Some think that these chemicals may have grave effects on the environment. Neverheless, industries that produce inks and toners would always insure their customers' safety. How about the Earth's protection?

The Earth is gradually changing due to man's excessive disposals and activities. Toxic chemicals have spread to main waters and will probably make it to the entire water system when attention is not given to it. So what can we do?

Using eco-friendly products will be of great help to our nature. Activities like the Earth Hour and Earth Day also create awareness and involvement for everyone. This month, the Earth Day is taking place on April 22, 2010. Many countries are anticipating this day to get involved and act for Mother Nature. Taking part in these events can make you a nature lover and it will teach you how to handle technology while taking care of the environment. In line with this international event, many companies offer great deals of support. These opportunities are worth the time and effort for you and for the world.

We began a new series titled becoming a computer skills guru. It was eye-opening to say the least (if you did not read that issue, you will do well to find and read it now, that is the background to what we are doing today and the next few weeks). And I promised that I would begin taking you through the three routes to becoming a computer skills guru on the computer. The routes were given as:

• Register with a Trainer
• Train yourself
• Acquire tutorial software

I told you, you could use one, or two, or all of the three, any or all will work, so, beginning today, I'll show you how the work and their merits. We'll go one step after another.

Register With a Trainer
This is about the best of all (if done right), because by this, you will stand on the shoulder of giants, thereby standing taller than your equals. What kind of trainer can you register with?
This is the very important question! You can not just go anywhere and register yourself with them because they say they are a computer school. These are the questions you should ask yourself:

• Do they really know the job?
• Do they really have the equipment to train people?
• Do they have the professionalism to teach and train?
• What is their track record over the years?
• What is their bill?
• Do they give their clients the required attention?
• Do they operate an on-the-job process for their clients?

These are the important questions you need to ask before you put your name, money and time into a particular place or person (trainer).

I know some quacks with big names, yet they know and do nothing at their training school, only ripping innocent and unknowing persons (clients) off their money, after all those people (the clients) know nothing too, and since they do not know, they will not know they are being cheated, until it is too late.

In the same vein, I know good trainers too who are really good on the job.

If you are asking why is my computer running so slow it is not always a solution to take your computer to a repair shop or even buy a new computer because your computer is very slow. There is a solution to this problem since your computer will not be running slow for the rest of its life span. Your computer was running fast before it started slowing down so there is a big possibility that you can make it run fast again.

You may be wondering on how you can do that and the answers are right here. All you have to do is follow these simple steps so that your computer will run faster again.

Step 1: Check if you are running too many programs.

When you are very busy doing something in front of your computer you may not notice that you are running a lot of programs. This is a common reason. There is also a possibility that you have a lot of programs that are set to auto-start during the start up of your computer. Just make sure that there are only a few programs that are running while you are using your computer.

Step 2: Scan your hard drive for potential viruses.

A very real threat to your computer is viruses which you could get from USB flash drives, the internet and other devices. These viruses that can damage your computer can slow down your computer and you can fix the problem with the help of any kind of virus scanner. Just remember that your virus scanner needs to be updated so that new viruses can not escape your virus scanner and all viruses will be detected and cleaned. and this will help you find out why my computer is running so slow.

Step 3: Download and install a registry cleaner on your computer.

It is not only viruses that can affect your computers performance but errors and corruption in your windows registry. You can fix this problem with the use of a registry cleaner. Simply download and install one and scan your computer and it will automatically fix the problem for you and help speed up your slow computer in minutes.

There is no 100% protection for your computer. But this does not mean you can not prevent you data to be unauthorized access.

Once I was chatting with my colleagues about the security issues and the ways the information can be protected. Our main goal was to understand if the Dekart family products could be used for assuring data access protection. We were talking about existing software, about the devices available for buyers and about the percentage of an assurance we can get from these tools available on the modern market so far. We also touched the other side of protection: it's vulnerability. We came to the conclusion that it is not simple to get the information protected, as there are many well-established strategies and methods developers (to say purely), which target is to get to know what is valuable for you.

But anyway there are the directions we can work on in order to minimize the risks for unauthorized access to our data. Here are they.

1. If you want to protect your data it is important to secure the building (office, home), security access and protection. There are many security agencies available on the market, which can be of real help. They have different protection strategies and tools. But as this is not directly related to your computer we will let the specialists in the area to let us know about it and we will move forward.

2. Hardware protection. There are many tools available for computer protection, like physical computers locks, which may be locked through a hole in the desk / object, or can be locked to a mounting bracket affixed to the vertical surface. There are different kits, mostly consist of security cables and locks. These anti-theft devices are designed for Notebook laptops and PCs, with special requirements adjusted for different models.

3. Computer data access limiting. There are tolls and software, which may be used for home and business computer access protection. The multifactor authentication (with password, pin code and biometric data) can be used with Dekart Logon software, which can be of real help for storing all passwords to Windows machines on one removable storage device and adding the strong authentication and convenience to the standard Windows logon procedure.

4. Information encryption. While we were talking about these issues, we were able to note that there is a tool which can protect data, even if it is stolen, even if there will be the most brilliant software hackers working on getting to know it. It is amazing! We were surprised to get to know that any important data can be stored and encrypted with Dekart Private Disk, which is an easy-to-use, reliable, user-friendly and smart program. It is of real help in creating encrypted disk partitions (drive letters) to keep private and confidential data secure. It uses 256-bit Advanced Encryption Standard. So, here is a no risk solution to protect data!

5. E-mail protection.

6. And the last important thing to note is do not forget to assure that you have the same plans for the part of the world, as God has in terms of earth cracks, tsunami, etc.

Together with our colleges we came to conclusion that there is no perfect security environment, although it is not wise at all to stay unaware of the risks issued and to minimize the solutions to this issue available. At least we were satisfied with Dekart Products we were testing, so we decided to get Dekart Private Disk and Dekart Logon.

This is not so difficult topic to understand. We just wanted to encourage you to think of solutions implemented. Just look for the information and act!

Registry cleaner tools have been claimed to accelerate your PC and prevent errors. However, if you want to make your computer fast and reliable, you need to know if you have the suitable tools for your system.

Unfortunately, there are many registry cleaners that do not work very well in order to solve the problems in your computer. In fact, most of the cleaners on the Internet are not very effective. Although there are many such tools, and they are designed to do the same work to mend the part of Windows that is known as the 'Registry'. This is the central nervous system for Windows. It stores information including the latest documentation you use and your computer settings.

To solve problems in the registry, you need to use the registry cleaning tool that can scan and resolve the problems caused by this. Why do you need to clean up the registry? There are so many corrosions in the Windows. When this happens, it can not handle the file that needs, slowing it down, causing the error.
The best optimization of your computer registry clean-up is able to find and delete the most from your system registry for a variety of errors. The problem with most registry tools is that they only scan "empty registry keys". This is not conducive to your computer. You need a cleaner that will remove "invalid" registry settings and only a few tools can do so well.

We have been using a lot of registry cleaners in the past few years, having found that one called "Reg Utility" seems incredibly very good to resolve any Windows computer registry error. This is a universal tool, which has been Canada's leading software development design. From our tests, we found that Reg Utility can eliminate the safest approach.

If you have ever had a computer problem, at some point the thought that it could have been caused by a virus has crossed your mind. Perhaps your virus checking program has started telling you about all kinds of things it thinks it has found. Even if neither of those has happened, you will ever be confused with a problem from a virus. Perhaps even a backdoor virus or backdoor Trojan.

Disguise is the name of the game for these viruses. They will appear to be one thing but are really something else. They open a backdoor into your computer allowing the REALLY malicious acts to take place. Something could be installed on your computer or it could be something on your computer that simply watches your actions until it something catches its interest. Then this Trojan jumps into action and transfers whatever information it found to the computer it has been told to talk to. Your personal information can be stolen very easily in this manner. You have no idea it's even happened.

Viruses and Trojans typically have names that do not tell you much about it. What is really helpful is for the virus protection program to tell you the file or files that house and hold the code that runs the viruses. A good virus protection program should provide that information on most viruses it detects.

The virus protection program can attempt to disinfect you computer. Formatting your hard drive is the only guarantee you will get rid of a virus. But a good virus protection program can help a great deal. It will do its work, and provide information. Then if problems are still occurring the burden falls on you to try to eradicate the problem. This is where even more information can help.

You often will be told to search for files on your hard drive. Sometimes you will be given a directory to look in. However, one trick virtual all Trojans and viruses use is to have file names that look files currently in your operating system. This makes it more difficult and confusing to find the correct file. It could be just the extension is different or perhaps a single letter has been added to the file name. Below is a list of files that are used by some of the most common Trojans and viruses.

esktop.exe – Belongs to the Backdoor.SdBot.md Trojan and the FFIsearch Spyware.

desktop.smm – Belongs to the Backdoor.SdBot.md Trojan and the FFIsearch Spyware.

ddhelper32.exe – Contains the backdoor software BDS / Sub7-220.Srv and Backdoor.SubSeven.

sys.plg – Belongs to the Backdoor.ICR Trojan.

gld.exe – Belongs to the Backdoor.Zagaban Trojan.

rlid.exe – Added by LIXY Backdoor virus.

winupdate.exe – Added by WORM_FALSU and is a backdoor Trojan.

wupdt.exe – Added by IMISERV virus and backdoor Trojan.

tskdbg.exe – Added by FLOOD.E VIRUS.It and is a backdoor Trojan.

winstat.exe – Belongs to Kodorjan Trojan.Kodorjan backdoor Trojan.

There is much more information available. Using a search engine, search for the file that you are concerned about. You will get a list of links that describe the file or process you are searching for. There are many, many other viruses and Trojans. Many use other files. So it is necessary to always search.

Using Windows Task Manager (Ctrl + Alt + Del), and selecting the process tab you could see a process that seems to be doing a tremendous amount of work. But for some reason nothing is really happening. All that effort spent by the process could be going on behind the scenes. It's being performed by a backdoor Trojan virus. To get more information on what may be happening, go to the website stated above and search for the process name. It will tell you whether that process is safe. If it is not safe, often a course of action to follow is recommended. It may also give you some idea as to why it is working so hard!

In 1986, the World was introduced to the laptop computer. It is probably the best innovation of recent times, though it is tough call. Since the 1980's, we have seen a whole bunch of nifty, cutting edge electronics and gadgets, including video games and cellular phones. Of course, the laptop of the 80's was big, bulky, heavy and really, really expensive. These days, laptops are more affordable than ever, more lightweight, more stylish and getting on-line is a common task, even at restaurants.

People can conduct business from anywhere now, and they do. The new challenge of transporting your laptop safely to your destination has been met with the design of backpack computer bags that will protect your laptop during it's journey. Leaving home with a laptop computer is as familiar as grabbing the car keys and so is using a backpack for laptop carrying. What makes this different from a traditional backpack is that for one, there is a cushioned area that will be used to help with storing the laptop computer. A laptop backpack works simply as a protective backpack that can be used to store a laptop computer in.

There are always storage areas on the inside and outside of the backpack computer bags to accommodate the laptop power cord and other accessories, like a wireless network adapter and storage disks. There are different types of backpacks for different laptops because there are many laptop computer sizes on the market. It helps to check with the height, length and width of the laptop that is being used and how much space a backpack can handle when looking into the right type of backpack computer bags.

There are people who need it office purposes while there are others who need it for gaming purposes. All of these requirements have different specifications and it also becomes cheaper if you construct your own computer. Also, if you have built your own computer, it becomes easier for you to change the components or make repairs when there is some problem.

There are basically 8 steps which will help you in building your own computer. The first step is to figure out the purpose for the computer. Make a list of all the things that you need and as per it, find out which components which will work best with it. Make sure that you decide whether you are using brand new components or old pieces. The next step is to find a place where you can work without the normal problems of dust and disturbance. Also, make sure that there is no carpet as the presence of the same can lead to static problems. The next step is to unscrew all the parts and figure out the requirements. After this is done, get the feet, power supply and the inner fan for use. The motherboard should be kept handy for installation. Although most of the components come with screws nowdays, there is always the chance of getting one which does not. In this case, you will have to mount all the other parts before pairing the motherboard. Always remember that the screws should not be overtly tight as it may pose problems in the fitting of the computer.

The next step is to configure the motherboard along with the CPU and the cooler. Now attach the power cord to the motherboard by connecting it to the power outlet. There are also smaller power cords which need to be attached to the LED screen and other components. The next step out here is to install the hard drives and other disks by using the manual instructions that are given along with the hardware. This should be done carefully so that there is no untoward mishap. Finally, figure out which operating system is the best for your needs and install it accordingly. Now that all this is done you can sit back and enjoy!

Both carbon and carbonless paper can be used to make copies of documents without any electronic devices. There are differences in each kind, both in how they are made and their uses. Overall, 3-part carbonless paper is a more popular option than carbon paper alternatives, and here is why.

Carbon paper is the original version of electronic-free document copying. It is coated on one side with a dark, ink-like substance that usually contains carbon. It makes copies with the creation on the first document.

A sheet is put in between the original and blank sheet the user wants the copy to appear on. They write or type onto the original and the pressure from the application puts ink onto the blank sheet. This creates a carbon copy.

Carbon paper was first used around the 19th century with a patent for something called a stylographic writer. A few years later, another inventor created a typewriting machine using carbon paper as part of its function. This means carbon paper was discovered and growing around the same time.

Carbonless paper, also known as NCR paper, is a better and more popular alternative to carbon paper. It is stain free and biodegradable and easier to transfer. It also relies on pressure from a writing utensil in order to create the chemical reaction that leaves a copy on pages below the top copy.

To make two copies of a document, papers would have a white top sheet and one colored second sheet below. This is called a two-part or duplicate. To make three copies, there is a white top sheet and two colored sheets directly below. This is called a three-part or triplicate. Four copies would be called a four-part or quadruplicate.

Sometimes, users requires stacks of ten or more copies. This is easy to do with NCR paper. Carbonless copy paper is supplied to the end user collated in pads or books. They are bound into sets using glue or staple. Loose sets or continuous stationary is widely used in printers. Businesses can also specially order as many stacks of carbonless copy paper as needed.

For a 3 part carbonless paper, there are three sheets. The first is the CB sheet that is the original to be copies. The bottom part of the sheet is coated in a layer of microcapsules that contain color formers.

The CFB sheet is second. The top side is coated with a receptive layer which reacts chemically with the color former on the top CB sheet. On the bottom of the sheet, a transfer layer with microcapsules transfers the copy to the last sheet.

The third sheet, or CF sheet, is on the bottom of the set. The top side is the receptive layer which reacts with the microcapsules color former on the sheet above it. The receptive layer is most often manufactured using activated clays.

Carbon and carbonless paper is mostly used to make copies of receipts. It serves as a backup operation in case computer systems fail. These paper options are also used to transfer invoices, service tickets, sales order, and purchase orders. Carbon and carbonless paper is used by modern artists as a surface for beginning a painting.

Carbon paper has some unique uses. Police offers use carbon paper for evidence vouchers. Prison inmates are required to use carbon paper when writing letters or other notes so the prison has a copy. Business forms utilize carbon paper for purchase orders and invoices. Banks and small firms are the biggest buyers of carbon paper.

Carbon paper is also commonly used among tattoo artists. The artists can practice draw designs and show it to the customer as they work on it, making changes as needed. The paper is moistened and pressed to the skin to leave a carbon outline. Customers can also bring in a design or message they want tattooed and carbon paper transfers it.

Carbonless paper can be used for these uses and more. Quotes, legal forms, employment applications, insurance forms, proposals, and delivery forms all use carbonless paper. NCR paper can also be used for requisition forms, tracking manifests, and contracts.

Poor posture — an epidemic in 2010?

We all seem to be spending a higher percentage of our days hunched over our computers. Whether we’re at work, at the local Starbucks, or at home, most of us spend hours a day at a computer. Email and social media have become an integral part of our daily lives, and most of us are slouching while we’re at our computers.

To make matters worse, most of us are still spending significant time watching TV and driving, two activities where most people are not in ideal posture.

Remember you’re mother telling you to stand up straight? Well, think about today’s kids who are at a computer or playing video games for most of their days. Poor posture is rapidly becoming part of our culture and the negative effects go far beyond a sore neck and bad back.

Bad posture = poor health

People with poor posture suffer untold numbers of negative consequences. These can include obvious issues such as neck and back pain, misaligned spine, rounded, slumped shoulders, osteoporosis and arthritis. But it can also lead to less obvious side effects including decreased energy, poor organ function, abdominal discomfort, and scores of other problem.

Additionally, poor posture gives one the appearance of poor health, low self-esteem, and an overall lack of confidence.

Posture corrective braces, the miracle cure?

Traditional posture braces come in various sizes, materials and configurations. From thin, elastic, over-the-shoulder posture bras, to Velcro vests and back braces made of surgical tubing, they all attempt to do the same thing: pull one’s shoulders back to maintain an upright stance and straight, correct posture. The problem with most posture braces is that they actually do put the user into correct posture. So why would that be a problem?

The problem with traditional posture braces is that they do the work for you. The passive nature of having one’s shoulders pulled back serves to weaken the back muscles, which actually worsens one’s posture over time, thus defeating the very purpose of using a posture correction brace.

Most people who have tried traditional posture braces have experienced the discomfort, the chafing under the arms, and the difficulty of use most devices offer, but most don’t realize that in the process of trying to improve one’s posture, the user could actually be causing long-term atrophy of the muscles in the back that are required for good posture.

Having a new computer is great! Everything is working fine, all the features you want are there, and it's smooth and fast. You can surf the net quickly and very efficiently. It's like driving a new car, it's just a joy. That's because it has not had time to suffer the problems that can occur with use over time. Just like a car engine, it needs some fine tuning sometimes.

You can rest assured that if you do not do anything in the way of maintenance for your computer, it will come back to haunt you. As your computer gets some time and use under its belt, it will always begin to slow down. You may experience freezes or even crashes, unless you take some kind of action to clean up the things that are slowing it down, and clogging it up.

Once you troubleshoot these problems, many times you find that your registry is where the problem lies. All Windows computers have a Windows registry. This is a huge database of files that are used in the operation of your computer. Anytime you download something onto your computer, the registry receives files relating to the operation of this program. And when you choose to 'uninstall' these programs, many times all the files do not get taken out of the registry.

The result is that you now have a build-up of useless files clogging up the registry, and slowing down the performance of your machine. Other problems that add to this problem, are spyware, malware, and adware. There are some software programs that will leave a file in your registry so that after your trial period, you can not use their program any more without purchasing it. And all these useless files will accumulate, and build up after time. This means that your registry gets overloaded and it has to read through so many unnecessary files to run what you have, it takes it much longer to perform its functions.

The best way for you to counteract this problem, is to download a good registry cleaner from the internet. These cleaners are good at removing these unnecessary files that are clogging up your PC. You can get an idea about just how trashed your registry is from the free service that most of these programs offer. They will scan your registry, then tell you the amount of errors they find.

There are a lot of these programs available for downloading, and you want to make sure you use a good one. This may mean a little research before you buy, but it's worth the time. There are some with very good reputations, that can get your computer back into working condition with little effort on your part.

These days even the youngger sections are well aware about the computers and Internet. The obsession with the use of internet and computer has become manifold with mos of the tasks being undertaken online. The life of most of the people has become quite easier due to the usage of these advanced technologies. The computer functions according to the order given by the human being.

A computer that is decelerated can not be used by anyone.

Any person will get quite upset while working on a slow computer. The slow speed of PC will not only consume lots of time for doing things but will also make the person feel mentally tired and stressed out. Sometimes many of them come across such type of horrible issues with the system. The swiftness of the PC can be determined by various elements.

A computer might be technically failing to work on some applications. The system speed mat be going down due to some application that is not compatible with the users system and this must be taken care of.

There has also been a manipulation in the speed due to use of advanced software on enhancing the working of the system. When a person has loaded the system with a program that is not functioning properly on your system then it will be best to eliminate it and go for a minimal one.

A computer running slow may also be due to some errors or viruses so it is recommended to always run a PC on a safe and secure antivirus as it will keep away all those viruses, loading an antispyware will also be a great idea. The system must be protected with a good antivirus and antispyware running on it.

You can improve the speed of the computer by erasing some of the unwanted information that is having a load on the disk space.

You will be able to speed up the system by advancing the memory currently present in it.

There is a lot of invalid and split up data saved to the hard disk of the system at times. You must use the technique of separating the information from the slow computer.

Turning down some window graphics will help to speed up.

While working over web it is usually recommended to clear the history after use as it will clear all unwanted sites, cookies and files that are contributing to the slow speed of the computer. The system speed can be enhanced by making use of only 2 to 3 programs at a time. The more the number of instructions running on the system the more the system will be impeded.

The best way to learn about bitcoin, is to jump in and get a few in your “pocket” to get a feel for how they work.

Despite the hype about how difficult and dangerous it can be, getting bitcoins is a lot easier and safer than you might think. In a lot of ways, it is probably easier than opening an account at a traditional bank. And, given what has been happening in the banking system, it is probably safer too.

There are a few things to learn: getting and using a software wallet, learning how to send and receive money, learning how to buy bitcoin from a person or an exchange.

Preparation

Before getting started, you will need to get yourself a wallet. You can do this easily enough by registering with one of the exchanges which will host wallet for you. And, although I think you are going to want to have one or more exchange wallets eventually, you should start with one on your own computer both to get a better feel for bitcoin and because the exchanges are still experimental themselves. When we get to that stage of the discussion, I will be advising that you get in the habit of moving your money and coins off the exchanges or diversifying across exchanges to keep your money safe.

What is a wallet?

It is a way to store your bitcoins. Specifically, it is software that has been designed to store bitcoin. It can be run on your desktop computer, laptop, mobile device (except, as yet, Apple) and can also be made to store bitcoins on things like thumb drives. If you are concerned about being hacked, then that is a good option. Even the Winklevoss* twins, who have millions invested in bitcoin, put their investment on hard drives which they then put into a safety deposit box.

*The Winklevoss twins are the ones who originally had the idea for a social networking site that became Facebook. They hired Mark Zuckerberg who took their idea as his own and became immensely rich.

What do you need to know about having a bitcoin wallet on your computer?

Below you can download the original bitcoin wallet, or client, in Windows or Mac format. These are not just wallets, but are in fact part of the bitcoin network. They will receive, store, and send your bitcoins. You can create one or more addresses with a click (an address is a number that looks like this: 1LyFcQatbg4BvT9gGTz6VdqqHKpPn5QBuk). You will see a field where you can copy and paste a number like this from a person you want to send money to and off it will go directly into that person’s wallet. You can even create a QR code which will let someone take a picture with an app on their phone and send you some bitcoin. It is perfectly safe to give these out – the address and QR code are both for my donations page. Feel free to donate!

NOTE: This type of wallet acts both as a wallet for you and as part of the bitcoin system. The reason bitcoin works is that every transaction is broadcast and recorded as a number across the entire system (meaning that every transaction is confirmed and made irreversible by the network itself). Any computer with the right software can be part of that system, checking and supporting the network. This wallet serves as your personal wallet and also as a support for that system. Therefore, be aware that it will take up 8-9 gigabytes of your computer‘s memory. After you install the wallet, it will take as much as a day for the wallet to sync with the network. This is normal, does not harm your computer, and makes the system as a whole more secure, so it’s a good idea.

Bitcoin Qt

• The original wallet.
• This is a full-featured wallet: create multiple addresses to receive bitcoins, send bitcoins easily, track transactions, and back up your wallet.
• Outside of the time it takes to sync, this is a very easy to use option.
• Search for Bitcoin Qt wallet download to find their site.

Armory

• Runs on top of Bitcoi Qt, so it has all of the same syncing requirements.
• Armory allows you to back up, encrypt, and the ability to store your bitcoins off line.
• Search for Bitcoin Armory Wallet to find their site.

If you don’t want to have that much memory used or don’t want to wait for your wallet to sync, there are good wallets that do not make you sync the entire history of bitcocin:

Multibit

• A lightweight wallet that syncs quickly. This is very good for new users.
• Search for Bitcoin Multibit Wallet to find their site.

Electum

• In addition to being quick and light, this wallet allows you to recover lost data using a passcode.
• Search for Bitcoin Electum Wallet to find their site.

After you get the wallet set up, take a few minutes clicking around. Things to look for:

o There will be a page that shows you how many bitcoins are currently in your wallet. Keep in mind that bitcoins can be broken up into smaller pieces, so you may see a decimal with a lot of zeros after it. (Interesting note, 0.00000001 is one Satoshi, named after the pseudonymous creator of bitcoin).

o There will be an area showing what your recent transactions are.

o There will be an area where you can create an address and a QR code (like the one I have above). You don’t need the QR code if you don’t want it, but if you run a business and you want to accept bitcoin, then all you’ll need to do to accept payment is to show someone the QR code, let them take a picture of it, and they will be able to send you some money. You will also be able to create as many addresses as you like, so if you want to track where the money is coming from, you could have a separately labeled address from each one of your payees.

o There will be an area with a box for you to paste a code when you want to send money to someone or to yourself on an exchange or different wallet.

There will be other options and features, but to start out with, these are the items that you should know about.

Getting Your First Bitcoins

Now that you have a wallet, you will, of course, want to test them out.

The very first place to go is http://faucet.bitcoin.st/.

This is a website that gives out small amounts of bitcoin for the purpose of getting people used to using them. The original version of this was run by the lead developer of bitcoin, Gavin Andreson. That site has since closed and this site operates by sending out one or two advertisements a month. You agree to receive those messages by requesting the bitcoins. Copy and paste your new bitcoin address and enter a phone number to which you can receive an SMS. They send out an SMS to be sure that people are not continuously coming back for more since it costs nothing to create a bitcoin address. They will also send out once or twice a month advertisement to support their operation. The amount they send it trivial: 0.0015 BTC (or 1.5 mBTC). However, they process almost immediately and you can check to see that your address and wallet are working. It is also quite a feeling to get that portion of a bitcoin. (Non-disclaimer: I have no connection with this site and receive nothing if you use them. I simply think they are a good way to get your feet wet).

Congratulations! You have just entered the bitcoin economy.

To get your feet a little wetter, you can go panning for gold. There are a number of services and websites out there that will pay you in bitcoin to do things like go to certain websites, fill out online surveys, or watch sponsored videos. These are harmless, and you can earn a few extra bitcoins this way, but it is important to remember that these are businesses that get paid when people click on the links on their sites. They are essentially kicking back a portion of what they get paid to you. There is nothing illegal, or even immoral about this (you might like what you see and make a purchase!), but they are frequently flashy and may not be completely straightforward. All the ones that I have tried (particularly bitvisitor.com) have paid out as advertised. It is interesting to experiment with these, but even with the likely rise in the value of bitcoin, you won’t become a millionaire doing this. So, unless you are an advertisement junkie, I would recommend you move on. If you would like to try, simply Google “free bitcoins” or something along those lines and you will find numerous sites.

Buying Bitcoin Hand-to-Hand

Finally, this is going to be the real test of bitcoin. Can people easily trade them back and forth? If this can’t happen, then there can’t really be a bitcoin economy because retailers won’t be able to use it. If retailers can’t use it, what earthly good is it? Fortunately, this is not really a problem. iPhone is a bit of a hold out, but many smartphones have apps (mobile wallets) that will read QR codes and allow you to send bitcoin to whomever you want. You can also display a QR code of your address, or even carry a card in your wallet with your QR code to let people send bitcoin to you. Depending on what kind of wallet you have, you can then check to see if the bitcoins have been received.

A couple of things to note:

• When you set up your wallet, if you click around a bit, you will see an option to pay a fee to speed transactions. This money becomes available to a bitcoin miner as he/she/they process bitcoin information. The miners doing the work of creating blocks of information keeps the system up to date and secure. The fee is an incentive to the miner to be sure to include your information in the next information block and therefore “verify” it. In the short term, miners are making most of their money by mining new coins (check the section on What Are Bitcoins for more information about this). In the long term, as it gets harder to find new coins, and as the economy increases, the fees will be an incentive for miners to keep creating more blocks and keep the economy going. Your wallet should be set to pay 0 fees as a default, but if you want, you can add a fee to prioritize your transactions. You are under no obligation to pay a fee, and many organizations that process many small transactions (like the ones that pan for gold described above) produce enough fees to keep the miners happy.
• In clicking around your wallet, on the transactions page or linked to specific transactions, you will see a note about confirmations. When you make a transaction, that information is sent out into the network and the network will send back a confirmation that there is no double entry for that bitcoin. It is smart to wait until you get several confirmations before walking away from someone who has paid you. It is actually not very easy to scam someone hand-to-hand like this, and it is not very cost-effective for the criminal, but it can be done.

Where can you buy bitcoin like this?

• You may have a bitcoin Meetup in your area.
• You can check out localbitcoins.com to find people near you who are interested in buying or selling.
• Some are trying to start up local street exchanges across the world. These are called Buttonwoods after the first street exchange established on Wall Street in 1792 under a buttonwood tree. See if there is one, or start one, in your area.
• See if you have any friends who would like to try bitcoins out. Actually, the more people who start using bitcoin, the larger and more successful it will be come. So please tell two friends!

Some people ask if it is possible to buy physical bitcoins. The answer to this is both a yes and a no. Bitcoin, by its very nature, is a digital currency and has no physical form. However, there are a couple of ways that you can practically hold a bitcoin in your hands:

• Cascascius Coins: These are the brainchild of Mike Caldwell. He mints physical coins and then embeds the private keys for the bitcoins inside them. You can get the private key by peeling a hologram from the coin which will then clearly show that the coin has been tampered with. Mike has gone out of his way to ensure that he can be trusted. These are a good investment strategy as in the years to come it may be that these coins are huge collector’s items.
• Paper Wallets: A paper wallet just means that rather than keeping the information for your bitcoin stored in a digital wallet, you print the key information off along with a private key and keep it safe in a safe, in a drawer, or in your mattress (if you like). This is highly recommended and cost effective system for keeping your bitcoin safe. Keep in mind, though, that someone could steal them or if your house burns, they will go with the house and there will be no way to get them back. Really, no different than cash. Also, as with Casascius Coins, they will not really be good for spending until you put them back into the computer.

* There is software to make printing your paper wallets easier. bitcoinpaperwallet.com is one of the best and includes a good tutorial about how to use them.

* The bitcoins are not actually in the wallet, they are still on the web. In fact, the outside of the wallet will have a QR code that will allow you ship coins to the wallet any time you like.

* The sealed part of the wallet will have the private key without which you cannot access the coins. Therefore, only put as many coins on the wallet as you want to be inaccessible. You will not be able to whip this thing out and take out a few coins to buy a cup of coffee. Rather, think of it as a piggy bank. To get the money, you have to smash it. It is possible to take out smaller amounts, but at this point the security of the wallet is compromised and it would be easier for someone to steal the coins. Better to have them all in or out.

* People who use paper wallets are usually security conscious, and there are a number of ways for the nefarious in the world to hack your computer. Bitcoinpaperwallet.com gives a lot of good advice about how to print your wallets securely.

Some people have also asked about buying bitcoins on eBay. Yes, it is possible, but they will be far overpriced. So, selling on eBay might seem to be a better option given the extreme markup over market value you might see. But, as with anything that is too good to be true, this is too good to be true. As I will explain in the next section, selling bitcoin this way is just way too risky.

How Not to Buy Bitcoin

In the next section, I am going to explain a couple of key points about buying from Bitcoin Exchanges. Before I do, let me give you a warning.

A short history lesson: When people first started setting up actual business based on bitcoin, they used all of the tools available to any merchant. They sold by credit card and PayPal. The problem with this business model was quickly spotted: bitcoin transactions are not reversible by anyone except the recipient of the money. Credit cards and PayPal have strong buyer protection policies that make it relatively easy for people to request a chargeback. So, nefarious individuals realized this and began making purchases of bitcoin and then sooner or later requesting a chargeback. And, since bitcoin is a non-physical product, sent by new and poorly understood technological means, the sellers were not able to contest this. Because of this, sellers stopped accepting credit cards and PayPal.

This was a big problem for the currency: How to move money between buyers and seller? Some business emerged that would credit you with bitcoin if you wired them money. Very often these businesses would give addresses in Albania, Poland, or Russia. The fact is that many of these did work and there are a lot of stories on the forums of people who bought bitcoins this way. But it took a lot of time and in the meantime the buyer just had to bite his or her fingernails wondering if they would get their bitcoins or kiss their investment goodbye.

I expect that as bitcoin becomes more acceptable and valuable, we are going to see a version of the Nigerian Prince scam. So the warning is this: we now have exchanges and other businesses that allow for moving money easily onto and off of exchanges. Never wire money for bitcoin. It was a short-lived, and well-forgotten, moment in the history of bitcoin.

Next, I will be talking about how to buy from a bitcoin exchange and give a review of the some of the best known exchanges.

Casio have been making keyboards for quite a while now and their name is synonymous with electronic keyboards, so you’d expect them to do what they do well, which they do. Casio are particularly good at making entry-level digital keyboards and they have a wide variety to choose from. This article will help you to choose the right one for you.

There are basically two ranges with different models within those ranges – the LK digital keyboard range, and the CTK range of keyboards. To look at the two ranges there isn’t a huge amount of difference to the untrained eye. But once you delve further into the functions and features there is a marked difference.

The main difference between the Casio LK and CTK digital keyboards is that the LK range, have what they call a back light keyboard. The back light keyboard is a tried and trusted feature designed to help absolute beginners to start learning and playing quickly.

We use Casio LK digital keyboards in our own music school and I’ve seen countless kids and adults find this to be one of the most useful training tools, but especially for younger learners as they can become frustrated and unfocused if they can’t learn quickly. I’m not saying you’ll become a piano maestro immediately upon using the tool – it just provides a very practical learning guide.

There are 5 models in the Casio LK range of keyboard: LK-120, LK-220, LK-230, LK-270 & LK-300TV. All of these models have 61 keys which all light up. 61 keys are plenty to be getting on with for absolute beginners. The Casio LK-120 is the entry level and goes up to the LK-300TV at the top end. Each model has slightly more features as you go up the range. For instance the LK-120 has 100 onboard sounds whereas the LK-300TV has 514.

Similarly the LK-120 has less rhythm choices than the LK-300TV digital keyboard. As you go up the range you’ll find more features such as effects e.g. delay, reverb. The ability to connect outboard gear becomes possible as you go up the range e.g. adding a microphone and playing along to someone singing. One thing that is common throughout the models is the capability to connect to a computer easily either through Midi or USB. They also feature the Casio Step up learning system.

The Casio CTK-range is also suitable for absolute beginners but do not feature the back light keys. They do however all feature the Step-Up learning system as well more recording, sampling and effects features.

There are 6 models in the CTK range; CTK-230, CTK-2000, CTK-2100, CTK-3000, CTK-4000 and the CTK-5000. As with the LK range of digital keyboards, the CTK range increases the number of on-board sounds, digital effects as you go up the range. The CTK-230 is the entry level, and it should be pointed out that it only has 49 keys, where as the others all have 61 keys.

Another feature of the CTK range worth mentioning is the appearance of the keys. On a lot of keyboards at this price range, you can find that they keys are a different size to those of an acoustic piano. Casio have made the keys to be the same size and to look the same as an acoustic. All of which helps with playing technique.

So the question is which is the best Casio keyboard for beginners? There is no right or wrong, but as a guideline, I would chose the LK-230 absolute beginners who are younger i.e. 4-7 years old. For older players I would choose the CTK range.

Most business today live and die with their network computer systems but what does it take to keep them running reliably?

1. Anti virus software, PC viruses are so prevalent today that it is false economy to try to run without it. Even if you are on a private network and think you are safe, all it takes is one person plugging in a SUB drive. Plugging a SUB drive in to your computer triggers auto run and the virus spreads from there.
2. Avoid turning off your computer by the power switch – always do it through Windows. This can cause lost data, disk failure and a host of problems. Sometimes you may need to do this if your computer hangs up, otherwise avoid it.
3. Be sure that your key computers, if not all of your computers are on a UPS. A UPS keeps the power on even during power failures. As seen in the previous point it is dangerous to do a hard power down and a UPS will avoid it. A UPS will also protect you from power spikes and similar computer damage transients on your power.
4. Backup any data that you can not afford to use. There are many on line backup systems that stores your data off site and there are inexpensive external disk drives that you can connect. Just be sure to do it at least daily.
5. Keep you disk drives healthy and happy, keep your computer running fast by running check disk to clear up problems that may exist and follow that with a fragment. There are programs that can run all the time and def rag as you go.
6. Keep at least 20% free space on your drives. This allows the OS plenty of room to operate and it allows proper fragmenting to happen. As your disk free space shrinks the machine will slow.
7. If you connect to the Internet you need a firewall on your network and on your machines to provide maximum protection from hackers and computer evil doers.
8. Keep your software disks safely filed somewhere. At some point one of your computers will crash and you will need to repair it and reinstall the operating system and all programs. At many businesses these materials are filed haphazardly, perhaps thrown in a drawer or a file folder. Set up a system for storing your programs so they can easily be found. Of course the data backups talked about in point 4 are also needed so be sure to do that.

You might be worried about your VHS collection, particularly about how to keep that precious media lasting longer, as well as the space requirements it takes to store all of those bulky tapes. In order to carry out a successful VHS to DVD conversion, you have to know how exactly the process works, and how the two formats are different.

VHS records things in analog. A magnetic tape is coded with the information that makes up the film in the form of magnetic fields. As time goes on, this information can start to lose quality and fade away, until you cannot see the information anymore. Digital video comes in the form of DVD. Digital information is put on these discs which are in the form of computer information, providing a much longer lasting medium for your films and shows than VHS.

Given the differences between the two formats, you have to discern a method to convert from analog to digital, requiring the use of a VHS to DVD converter for your particular duties, so that should be your first step. You can find plenty of avenues by which to get one of these devices, and your particular needs and budget will determine what you actually need to get.

Computer-Based Converters

In order to use these new methods, you will really need to learn how to use computers and technology. You will require an analog-to-digital converter in order to implement these methods, and despite the simple nature of some of these strategies, you might have to work to learn how to do others. However, the most advanced the technique, the more leeway and freedom you will have to do with your footage as you will.

Capture Boxes and Cards For Your VHS Tapes

When you convert a VHS tape to a DVD, you might end up with a slight lowering in video quality. If you want the most appealing results, you will want an MPEG-2 encoder, which will use a DVD-friendly format. If you buy a USB encoder box or video capture card, you will have the high quality encoder chip required to convert your video, as your processor will not be a part of this process, all the work falling to the converter box. The final product will then be cleaner and clearer, especially if contrasted with the DV Camcorder. Keep in mind that you will experience a slight decrease in picture quality when you convert from analog to DV, then straight to DVD after that – artifacts can occur that just look terrible.

Despite the fact that it will take a lot of technical know how to pull of this last method, you will get fantastic picture given the right software. If your software has the right features, you could turn your VHS tape into a full blown DVD, complete with menus and transitions, making it look extremely professional.

DVD Recorders

The DVD equivalent of a VCR is the DVD Recorder, and it will work pretty much like it in terms of function. It can play the DVDs that you insert in it, and you can also hook it up to your television and record what is on screen. Now, you may need to learn the best way to do this in order to get it to work, but as long as you have recorded stuff from a TV onto a VHS before, you should be fine. As an extra bonus, the copy protected movies will be able to be recorded with the help of these devices.

VHS to DVD Recorders

You will find the easiest way to do this conversion with this device. Basically, a VHS to DVD recorder has both a DVD burner and a VHS player inside. Just put both your VHS and DVD media in, and you will dub over the DVD with the VHS footage, much like you could with two VHSs. Those of you who do not have a lot of experience with technology or electronics, you might find this the most effective and easy to use. On the other hand, you will not be able to transfer your copy protected movies to DVD with this device, making it not the ideal solution.

DV/Digital 8 Camcorders

You will be able to use digital camcorders to convert between analog and digital. Just connect the camcorder between your computer and your VCR, and your VHS to DVD converter is now completed and ready to go. Your VCR will send the signals into your digital camera, storing them in that format. Your camcorder will then send the data to your computer as a digital video file, which is done via the USB cable or FireWire cable you have hooked into it.

Prior to implementing this method, you do have to consider a few technical issues that may arise. You might need a lot of storage space, as DV files can take 14 gigabytes in order to record an hour. More space is needed to convert the file to DVD and burn the disk itself.

VHS to DVD Conversion Service

While this might be the most expensive method to convert your tape, it will require the least amount of work and education on your part. You can hire on the VHS to DVD conversion services of one of many companies online or in your area in order to get the tapes that you want put on DVD. You might have to pay a lot of money though, as much as $100 a tape to get all the nice features.

The price is the only real downside to this option, however. For that price, though, you can get tapes cleaned up so the quality is vastly improved, which is something you may not have the expertise or time to do. Therefore, you should not feel you have no options when it comes to converting your old tapes to DVDs; it just depends on the hardware that you have and the time you want to commit.

Dual monitors or multi monitor as it is more commonly known is a term used when there are more than one display device is used. This could be monitors or projectors or even televisions. The reasons why two monitors are preferred for programs running on a computer is because of its increase in area that allows increase in productivity of the user. With the popularity of this concept it has been increasingly used by video editors, graphic designers and game developers. These days there are numerous games too that support dual monitors too. However it does come with its own share of disadvantages too. Given below are some of the advantages and disadvantages of the gaming with two monitors and some games that allow gaming using dual monitors.

Advantages

Two monitors are always betters than one, especially when it comes to gaming. The first and foremost benefit is the screen space. With the large screen space that is available to the gamers, it gives them an enhanced gaming experience. Especially in the games where the gamer has to be more worried and concerned about the horizontal landscape rather than the vertical one, dual monitor comes in use here. By using dual monitors the player is able to have a larger and a much more realistic view of what the character in the game is able to view.

A good example of gaming with Multiple Monitors is un World of Warcraft. This MMORPG allows the user to don the role of an on screen avatar and controls all the actions of that avatar like exploring, fighting, interacting with other characters and much more. This game can beset up to be played with a dual monitor so enhancing the gaming experience of the user. Using Dual Monitor also allows the player to view different instances of the same game on different monitor without getting confused or losing focus on the game rather than trying to view all the instances on one single monitor.

Disadvantages

Like all technology, even using two monitors has its own disadvantages. We have listed some of them for you in this article. The main problem that crops up while using dual monitors is with the vertical size. While the increase in the horizontal view is good for gamers as they are able to view several instances, the increase in the vertical view becomes very uncomfortable for the user. The other main disadvantage is with the sharing of resources. The resources of the video card are shared between both the monitors which could lead to a reduced performance from the processor and the video memory, so not allowing the users to enjoy the desired output.

Games that allow using dual monitors

There are several games that allow the use of multiple monitors while playing. Clear the Swarm was the first web game that supported multi monitors. This game's entry into the market saw several other games like Microsoft Flight Simulator 2000, Supreme Commander, World In Conflict, DOOM, Burnout Paradise, Dirt 2, Team Fortress 2 and World of Warcraft into the market that can be played with dual monitors.

Fix a slow running computer!

Well, if you notice that your computer is running at a slower speed than what it used to initially, here are a few steps to fix a slow running computer and increase its speed and performance.

You may not notice that your computer runs very slow or hangs when you try and run a lot of programs all at once, as soon as your PC boots. So the trick is, let all your applications open and then start working on the PC, once it boots.

Next, delete your cookies regularly and empty the recycle bin and temporary internet files on a weekly basis. This would remove all the excess junk that gets stored on your PC during surfing.

Try and keep as few items in the system tray as possible. The more the clutter, the less the speed and performance. You can organize the system tray icons by going to the start up menu in msconfig.

Try and keep the screen resolution at the lower end. The lesser it is, the better will be the speed of your PC.

During boot each and every font stored on your PC loads too, so if you have lots of fonts installed, there are chances of your computer slowing down drastically. Uninstall those fonts that you severely use. Before removing any, make sure they are not the system fonts.

Keep the C drive as empty as possible. Just load the windows on it. You can install the softwares on the other drives since windows uses the entire empty space in C drive as virtual memory when your Computer RAM is full.

Minimize the applications that are not being used. We can increase the amount of available RAM this way. When we minimize an application it indicates that it will not be utilized by the user right now. Therefore, the OS automatically makes the application use virtual memory and keeps minimum amount of the code in physical RAM.

Cleaning your registry at regular intervals also helps. For that you can download a registry cleaner from a trusted and a good website.

Also, defragment your hard drive and clean the unnecessary files and folders regularly. Do not allow the junk to collect on your machine.

Install a good antivirus and anti-spyware software. This software will identify and remove known viruses and spyware as well as help you identify safe websites and screen your downloads.

Spyware and malware can affect computer speed by using your computer resources for unauthorized tasks or even ruining other programs. Make sure your software is up to date and scan your computer often.

Last but not the least, keep your RAM upgraded. RAM is a place where your computer temporarily stores data for calculations. The more RAM your computer has, the bigger its capacity to do multiple tasks. Adding additional RAM can significantly increase your computer speed.

This review of the full version Risk I game download includes details of how it is played and the benefits of playing this Risk game download on your PC. The popular classic board game is a world domination strategy competition, where the board is a map of the world separated into territories. The main aim is to use your troops to take over all the territories and basically dominate the map with your army. The computer adaptation is an excellent reproduction. And with the extra benefits of playing this electronic version, makes it well worth downloading.

In this Risk PC game adaptation, you begin with naming your General and choosing 2 opponents to play against. Either other people playing on the same PC or computer controlled (A.I.) generals. There are 16 different generals to choose from, all named after famous generals from history. They are each given a rating, so if you are newbie you would opt for a general with a 1 star rating for ‘easy’ level whilst once you have had more practise you may want tougher opposition and so you can choose a general with a 5 star rating.

Just like the board game, all the players are given the same amount of troops which you will distribute around the board map within the territories you own. But in this version there are 2 modes; you can choose to share out the countries using the classic board method called the Territory Claim mode or the Random Deal mode which is where you allow the PC to share out the territories.

Once all the players’ armies have been placed on the map, you start the game. The aim is to dominate the world map, which you do by trying to overtake each opposing army that is in a neighbouring territory to yours.

You start your turn by choosing which bordering territory you want to attack, making sure you have at least two groups of armies in the territory you are attacking from. The fight for the territory begins. This is done by both the attacker and defender rolling the dice, which is done graphically by clicking on ‘roll’ to roll the dice. Whoever gets the highest number on the dice wins that battle, which results in knocking out one of the losers army. The attacker can choose to roll again until they completely defeat the defenders armies or until the attacker runs out of armies (remember that the attacker must have a minimum of 2 armies in the attacking country).

You can choose to attack a number of countries within your go and once you have finished, it is the next players turn to make attacks to try and take over countries. Like the original you get reinforcements if you own a whole continent and collect bonus cards which you can then trade in for extra cavalry, infantry or artillery.

The additional benefits to playing this full Risk I game on your PC include:

• You can play against the computer with A.I. generals – so you can play it whenever you want
• There is background music, sound effects, voice-overs for the A.I. generals and animation that enhance and make the game more fun
• You can speed up the setting of the armies, by choosing the Random deal mode
• With the full version download of this Risk game you can play unlimited Risk games on your PC
• It’s great to play for a bit of nostalgia for fans of the original
