Local Area Network (LAN) Definition/Meaning:
A communication network linking a number of stations in
the same "local" area, variously defined as the same building, a radius of one
kilometer, or a single plant.
Local area networks generally provide high-speed
(100K bps to 100M bps) data communication services to directly connected
computers. Gateways are used to connect local networks to each other, or to
longer-distance communication networks. Due to limited distance, controlled
environments, and (usually) homogeneous implementation, local networks have very
low error rates and can utilize simplified data communication protocols.
also wide area network.
