Lan Networking

A local-area network (LAN) is a computer network that is a connect small area. Most often, a LAN is confined to a single room or office, building or group of buildings, however, one LAN can be connected to other LANs over any distance via switch or hub. A system of LAN connected in this way is called a wide-area network.

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.
