LAN

Local Area Network. A network of connected devices (such as PCs, printers, servers and hubs) covering a relatively small geographic area (usually not larger than a floor or building). LANs are characterized by high transmission speeds over short distances. Ethernet, FDDI and Token Ring are widely used technologies for configuring LANs.
