Question

differentiate between LAN ,WAN and MAN

Answer 1

LAN

LAN has smaller coverage range within the house or office premises or can at least connect from one building to the nearby building. Most of the LANs usually will have about 10 to 100 users. Multiple users in LAN time share the system. LAN has been developed to allow sharing of common resource such as printer,harddisk and modem to more than one PCs. 

WAN

WAN has coverage larger than LAN and mainly used for cellular applications supporting both voice and data applications. Larger network covering entire country or state is referred as WANs. Most WANs are telephone systems.

MAN

MAN occupies coverage in between LANs and WANs. MAN has distance coverage and data rate higher than LAN, but less than WAN. This is the major difference between LAN and MAN. MAN overlaps to some extent to geographical coverage requirement of WAN. A typical example of MAN is Local Cable TV system

Answer 2

A LAN (local area network) is a group of computers and network devices connected together, usually within the same building. By definition, the connections must be high speed and relatively inexpensive (e.g., token ring or Ethernet). Most Indiana University Bloomington departments are on LANs.

A MAN (metropolitan area network) is a larger network that usually spans several buildings in the same city or town. The IUB network is an example of a MAN.

A WAN (wide area network), in comparison to a MAN, is not restricted to a geographical location, although it might be confined within the bounds of a state or country. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive. The Internet is an example of a worldwide public WAN.
