What Are Local Area Networks?

ieee802-3A local area network, commonly abbreviated “LAN”, is a network made up of computers that are located in close physical proximity to one another. They do not used leased lines form telecommunications companies. The most common LAN networks include those located in households and those located within offices. In office environments, the LAN would refer to the network within the building, but would not include any interconnections between offices that make use of leased telecom lines.

A LAN, while it does not use leased telecom lines, can use multiple technologies. For example, a home LAN may use Ethernet cable and WLAN technology to provide connectivity, but is still considered a LAN based on the close geographical positions of the computers and other devices on the network. Because it uses a telecom line, a remote connection to a LAN would not constitute adding another computer to the LAN.
