Wireless Networks

Modern Computer Networking and Its Importance For Business

Computer networking is the connecting of two or more computers that allows them to share resources. It can be done between computers in a home, in a business, across a corporation, and even internationally. It can equally be defined as a method of connecting two or more computer systems together including printers and other devices. The benefits of networking are considerable, even on a network of only three systems. In computer networking there was never a truer statement than that this is a case of advantages experienced being far greater than the sum of the parts. PC networking is, as a consequence, a rapidly evolving discipline with many exciting opportunities. Challenges that arise in networking and particularly in the Internet tend to be truly global and have the potential to impact upon millions of users. One huge and growing impact is Internet shopping. Shopping online has grown over the last 10 years to become a huge market, and if a sales business does not today … [Read more...]

How Text Messaging Started

Text messaging or commonly called texting is the process of sending short messages from a mobile phone. The latest mobile phones are capable of sending as much as 20 pages containing 160 characters. These messages are commonly called SMS, texts or text messages. Text messaging technology uses an SMS gateway to hook up any mobile SMS service to an existing instant message service, Word Wide Web, PDA devices, personal computers and to any landline phone. Some devices with Bluetooth devices can connect to a mobile phone similar to a modem sending SMS through wireless networks. SMS have been widely used with either GSM or non GSM systems. Basically, text messaging intends to provide a means of sending message to one person to another no matter where they are as long as there is signal coverage from the mobile providers. This service is also used for automated systems primarily for the purpose of purchasing products and services for mobile phone. Text messaging is also widely used … [Read more...]

What Is Wardriving And How Can You Prevent It

Imagine a car equipped with nothing more than a laptop computer, a portable GPS receiver, and a wireless network card slowly strolls through your neighborhood. Unknown to any onlookers, this is no ordinary vehicle; rather, it is a wardriving machine. As the car strolls past homes and businesses, a wireless network card (available at any electronics store for as low as $ 25) scans for any wireless access points. Anyone with a wireless network (and there are many out there) is vulnerable. The computer is looking for what is called an SSID. An SSID is your wireless network name and it is being constantly transmitted by your access point, letting computers know of its presence. The wardriver uses software such as Netstumbler (for windows) or Cismet (for linux) to scan the airwaves for SSIDs. The program can track various access points at once and monitor the signal strength. These programs can also check to see if the network is encrypted. The wardriver will generally configure … [Read more...]

Methods of Computer Networking

Computer networks can be classified into three broad categories. Local area network (LAN) A local area network remains confined in a relatively small space. It is useful in providing services to a small number of people. Networks in small offices, and homes are some examples of LAN. Small office and Home networks are also peer-to-peer networks where minimum resource is used and each client shares their resources with other workstations in the network. Another LAN is a client-server network where every client remains connected to the server and each other. Servers in client-server networks are of different capacities. There are two types of client-server networks: Single-service servers performing single task, say, as a file server; and Print server performing multiple tasks, say, as file server, print server, conducting calculations and providing information to client on basis of result of the calculations. Ethernet cables, Wireless networks, or other types of wires … [Read more...]

How to Make Your Wireless Network (Wi-Fi) Hacker-Proof

Security has become second nature to people over the years, whether it be your home, car, or personal belongings. Our computers are no exception to this, as digital thieves are lurking everywhere, and can be almost impossible to detect by the average computer user. Preventing unauthorized access to your wireless home or business network (Wi-Fi) is an extremely important measure to take, as a hacker does not need to know you personally to target you, and they can be in a house or apartment nearby, or even parked in a car on the street. Wi-Fi hackers have been known to drive around neighborhoods searching for wireless networks in people's homes, gain access through various unlocked doors in a wireless router's configuration, and then have a field day with your information. In this article, we will go step by step through the different configurations of your wireless router that leave your network vulnerable, and what to change to make your network virtually hacker proof. … [Read more...]
