Metropolitan Area Network
A metropolitan
area network (MAN) is a computer network
in which two or more computers or communicating devices or networks which are
geographically separated but in same metropolitan city and are connected to
each other are said to be connected on MAN. Metropolitan limits are determined
by local municipal corporations; the larger the city, the bigger the MAN, the
smaller a metro city, smaller the MAN.
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. Laudan 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.
