LAN

Local Area Network. Usually a high speed network, normally confined to a single geographic area, allowing communications at either 10Mbps, 100Mbps or (rarely but up-coming) 1000Mbps. cf WAN.

LANs are typically implemented using Ethernet, Token Ring, Fast Ethernet, Fiber Distributed Interface (FDDI), Asynchronous Transfer Mode (ATM) or LocalTalk.
