Introduction to Network

  

"What is a Network ?"

A network is simply two or more computers, connected, so that they exchange information (such as e-mail messages or share resources (say, disk storage or printers). In most cases, this connection is made via fiber optic cables at extremely high speed by using impuleses of light. And in a wireless network, computers communicate by using radio signals.

In addition to the hardware that support a network, you also need special sftware to enable communication. In the early days of networking, you had to add this software to each computer on the network, Nowadays, network support is built in to all major operating systems, including all current versions of windows, macintosh operating systems, and linux.
