What is MAN

NIELIT O Level Solved Paper
Internet and Web Technology

Q: Define MAN. Write down three important features that discriminate MAN from WAN.

A metropolitan area network (MAN) is a network that connect users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.


MAN is used to combine into a network group located in different buildings into a single network. The diameter of such a network can range from 5 to 50 kilometers. As a rule, MAN does not belong to any particular organization, in most cases, a group of users or a provider who takes charge for the service own its connecting elements and other equipment.

It is also often used to provide public available connection to other networks using a WAN connection. There are many ways of classifying networks. The main criterion for classification is considering the administration method. That is, depending on how the network is organized and how it is controlled, it can be attributed to local or distributed, metropolitan or WAN. or her A network administrator manages a network or it’s segment


  • MAN is more reliable than WAN because it has more controlling than Wan so security is better
  • ITS not fully public network So performance of this network is constant apart from WAN performance affect by many aspect number users , network connectivity etc.
  • Speed of MAN is better than WAN
  • Not complicated as compare to WAN for connect a city or a campus.
  • Some installations allow multiple users to share the same high-speed Internet connection, thereby sharing the cost of the service and securing a better quality of service through collective bargaining and economies of scale.
