Definition: A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school, or a home. A LAN is useful for sharing resources like files, printers, games or other applications.
Most local area networks use Wi-Fi or Ethernet for connectivity between devices. (See also - Comparing Wired and Wireless Network Technology).
Each of these local networks may stand alone (disconnected from any other network) or may connect to other LANs and additionally a WAN (such as the Internet).
The smallest LAN consists of exactly two computers, while a large one can accommodate many thousands of computers. Most local networks enable devices to communicate over Internet Protocol (IP) through support built-in to each device's network operating system. (See also - Introduction to Network Adapters).
The term LAN party refers to a multiplayer computer gaming event where participants bring their own computers and build a temporary local network.
