Local area network is a computer network covering a small physical area like home, office, or small group of buildings like school, or airport.
The characteristic features of LAN are usually higher data-transfer rate, smaller geographic place, and lack of need for leased telecommunication lines.
Current wired LAN's are most likely to be based on Ethernet technology over unshielded twisted pair cabling and Wi-Fi technology, although new standards like ITU-T G.hn may be used in the future.
