Local area network

A local area network (LAN) is a computer network covering a small geographic

area, like a home, office, or group of buildings. The defining characteristics of LANs,

in contrast to Wide Area Networks (WANs), include their much higher data transfer

rates, smaller geographic range, and lack of a need for leased telecommunication

lines.

Ethernet over unshielded twisted pair cabling, and Wi-Fi are the two most common

technologies currently, but ARCNET, Token Ring and many others have been used in

the past.
