Metropolitan Area Network (MAN)

     MAN network is little larger than a LAN as it normally covers the area of a city. A television distribution like Cable Television (CATV) all follows this type of networking structure. MAN’s interest here is in the digital although some of them may use broadband coaxial cable as the transmission medium. This technology is new and it operates at high speeds (usually hundreds of megabit per second through several gigabits per second) over distances sufficient for a metropolitan area. So these are best adopted by governmental agencies and organization for their administrative works to carry out easily and rapidly around the metropolitian corners.

Wide Area Network (WAN):

WAN covers the wide area of geography around the world. In such type of networking, geographically isolated computers are linked by communication facilities like telecommunications or microwave relays. More typically, such technology involves two or more than two LANs situated far apart and are linked by telephone lines, dedicated telephone lines, or radio waves. The Internet is the largest Wide Area Network (WAN) in existence. Comparing to the freedom of LAN this type of networking have the direct or indirect involvement of public telecommunications authority.WAN is usually limited to use by large organization and government agencies due to high costs involved in building and maintaining them.Satellilte is the main transmission medium for WAN. An example of WAN is Intranet and Internet.
