<P> A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as a home, school, office building, or closely positioned group of buildings . Each computer or device on the network is a node . Wired LANs are most likely based on Ethernet technology . Newer standards such as ITU - T G.hn also provide a way to create a wired LAN using existing wiring, such as coaxial cables, telephone lines, and power lines . </P> <P> The defining characteristics of a LAN, in contrast to a wide area network (WAN), include higher data transfer rates, limited geographic range, and lack of reliance on leased lines to provide connectivity . Current Ethernet or other IEEE 802.3 LAN technologies operate at data transfer rates up to 100 Gbit / s, standarized by IEEE in 2010 . Currently, 400 Gbit / s Ethernet is being developed . </P> <P> A LAN can be connected to a WAN using a router . </P> <Dl> <Dt> Home area network </Dt> </Dl>
