METROPOLITAN AREA NETWORK (MAN): a computer network that is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities. These are also called as Campus Area Network (CAN).Ex Town. It has got greater data transfer rate that LAN and lesser than WAN.


WIDE AREA NETWORK (WAN): a computer network that covers a broad area i.e., any network whose communications links cross metropolitan, regional, or national boundaries. Ex Internet.
