local area network
A high-speed network communications system that connects a
variety of multiple computers within a limited geographical area,
such as one building or a group of buildings. It is a privately
owned communication network whose speed is upward of one
megabit per second. Using a LAN, multiple users can share
devices and files at higher speeds, faster response times, and
lower costs than with telephone lines.
