Local area network

Edit

Definitions[]

A local area network (LAN) is

“ an Internet Protocol (IP) network, composed of routers and LAN switches, that is used to connect nodes that are geographically close, usually within the same building.[1] ”
“ a computer network which connects computers within a relatively small geographic area. The most common form of LANs are Ethernet and token ring. Many LANs have a central server and one or more printers. ”
“ [a] group of computers and other devices dispersed over a relatively limited area and connected by a communications link that enables any device to interact with any other on the network.[2] ”
“ [a] data communication system that:
(a) Allows an arbitrary number of independent "data devices" to communicate directly with each other; and
(b) Is confined to a geographical area of moderate size (e.g., office building, plant, campus, warehouse).[3]
 ”

Overview[]

"Typically, a LAN is owned, operated, and managed locally rather than by a common carrier. A LAN usually, through a common network operating system, connects servers, workstations, printers, and mass storage devices, enabling users to share the resources and functionality provided by a LAN."[4]
