Computer networks that usually cover a limited range, for example within the boundary of a building or a campus. A computer network is two or more computers that communicate with each other. The primary usage of local-area networks (LANs) is the sharing of hardware, software, or information across a network with a limited geography (Fig. 1) and usually on telecommunications lines and equipment owned and/or operated by the local-area network's organization. Resource sharing provided by local-area networks improves efficiency and reduces overhead. See also: Computer; Electronic mail; Multimedia technology
