Local Area Networks (LANs)

Share This:

A local area network is often a network confined to one location, one building or one campus. These networks are composed of various components from desktop PC's, printers, servers to mainframes and other strange devices. All hosts on a LAN have addresses that fall in a single continuous and contiguous range. LANs usually do not contain routers. Internetworks contain routers.
