Metropolitan Area Networks
A metropolitan area network (MAN) is a computer network larger than a local area network, covering an area of a few city blocks to the area of an entire city, possibly also including the surrounding areas.
A MAN is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities.
MANs can also depend on communications channels of moderate-to-high data rates.
A MAN might be owned and operated by a single organization, but it usually will be used by many individuals and organizations.
MANs might also be owned and operated as public utilities. They will often provide means for inter networking of local networks.
Kenneth C. Laudon and Jane P. Laudon define a metropolitan area network as: “A Metropolitan Area Network (MAN) is a large computer network that spans a metropolitan area or campus. Its geographic scope falls between a WAN and LAN.
MANs provide Internet connectivity for LANs in a metropolitan region, and connect them to wider area networks like the Internet.”
