A network that connects computers in a small, pre-determined area (like a room, building or set of buildings). LANs can also be connected to each other via telephone lines and radio waves. Workstations and personal computers in an office are commonly connected to each other with a LAN. This allows them to have send/receive files and/or have access to the files and data. Each computer connected to a LAN is called a node.
A communications facility covering a relatively small geographic area (usually measured in buildings or blocks, not miles) which interconnects communications devices such as terminals, personal computers, servers, and host computers.
allowing multiple computers within a limited geographical area to communicate and share computer resources (see WAN).
