Types of communication network

 

Local Area Networks (LANs)

A computer communications network contained in a small area such as a commercial building is known as a local area network (LAN). The major benefit of a local area network is that it can help to reduce costs by allowing people and microcomputers to share expensive resources.

Metropolitan Area Networks (MANs)

The next larger network than LAN may be the Metropolitan Area Networks (MANs). MAN usually spans a geographical area that usually encompasses a city or county area. It interconnects various buildings or other facilities within this citywide area.

 wide area network(WAN)                           

A wide area network (WAN) is one that operates over a vast distance . Its nodes may span cities, states, or national boundaries. This network interconnects computers, LANS, BNs, MANS, and other data transmission facilities. Typically, WAN will employ communications circuits such as long- distance telephone wires, microwaves and satellites.
