“local area network”的概念、定义、翻译、参考文献-科学参考

local area network

Computer

A network that in general is operated as a subsidiary activity by a single organization for its own exclusive use, the typical LAN having an overall size of a few kilometres or less. Normally the organization is located on a single site, or a small number of nearby sites, and the LAN constitutes a single management and naming domain. LANs generally provide high-speed (100 Mbps to 1 Gbps) 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. See also metropolitan area network, wide area network.

Internet

A small network situated within a single building or a small number of buildings. It is often abbreviated to LAN. Such networks are used to connect entities such as computers, printers, and mass storage devices and to share information.

Electronics and Electrical Engineering

A network for linking computers together, typically personal computers, for sharing files, printers, and electronic mail. It usually provides high-speed data communication services to directly connected computers of a single organization; the typical size of a LAN is within a single building, but they can extend to a few hundred metres. LANs are characterized by a shared access medium, so that everyone can receive all messages transmitted on the LAN. LANs may be connected to each other or to longer-distance networks. See also wide area network.
