Computer networks

It is simply a group of interconnected computers. Most people working in office with more than a couple of computers will be using some form of network. As networks become easier to setup and maintain more home users are also setting up networks to share resource such as disk space, printers, Internet connections and access to software.
A network is basically two or more computers connected through a cable or wire which share resources. Network software controls how the computers communicate.
There are dozens of different types of networks which are impossible to cover in an introduction article. This article focuses on home and small business networks using some version of the Window operating system.
To connect computers each of the computers needs a network card with a connection that allows a cable to be connected to it. Computers can be connected directly through a bi-directional cable or through an other piece of hardware called a hub. The hub then connects all the computers in your local network together. Both solutions cost about the same but a hub allows more than two computers to connect. A hub can also be used to connect two local area networks together to create a wide area network.
