MAN (Metropolitan Area Network)

                 MAN consists of two or more local area networks or campus area networks together. It usually spans
                 several buildings in the same city or town. It covers an area ranging from 10 to 100 km. For example,
                 the Internet services provided to users in a city or the ATM network of any area fall under MAN.

                 WAN (Wide Area Network)

                 WAN covers a wide geographical area. In other words, it is a group of computers that are separated
                 by a large distance and tied together. It links different metropolitans and even countries across
                 national boundaries. The most popular example of WAN is the Internet: a collection of an infinite

                 number of computers spread across the world.
