AREA NETWORK

A PC can gain access to a server-PC for the programs or data it requires. But that is not all. A PC connected to a network can enable its operator to gain access to other PCs on the network as well. He can retrieve files from these computers as if they were on his/her own PC.

AREA NETWORK IS OF TWO TYPES:

a) Local Area Network (LAN)

b) Wide Area Network (WAN)

A LAN is generally limited to a single office or building. But WAN has a wider range. It has several LANs connected together.

The computers on a WAN can extend to an entire city or across an even larger area. They can be connected by modems to telephone lines or satellites.
