A Network is a group of inter-connected computers that allows people to the information and equipment.

A Network system connects the computers and peripherals with help of NIC (Network  Interface Cards) cables or wires and relevant software and provides us to exchange the Documents,e-mails,video,sound and images. the equipment's such as printer and modem can also be shared with a number of computers connected with each others networking.

Types of Networking

There are the three main types of networking

1) LAN (local Area Network)

   It connects the computers with help of cables or wires within a small geographical area like a building or a complex spreading over in few kilometers.

2) MAN (Metropolitan Area Network)

   It is a big brother of LAN and works similar to it. It covers a group of nearby corporate offices or entire city. It may be either private or public.

3) WAN (Wide Area Network)

   It connects the computer across a large geographical area spreading over cities, states , countries  or continents. the information transmission media may phones lines or satellites. It is controlled by an authority, telephone line company or a government.
