Types OF Network

Computer Network defines as the group of computer system which hare linked with one another in order to share data, information or resources etc. with one another. So this group of Computer System may be small or may be large enough, also the method of inter-connection (connection between nodes or host) may be different as per condition, because computer network is vary with respect to size, geographical area and complexity.

So on the basic of geographical region, Network are classified as

1. Local Area Network (LAN)
2. Metropolitan Area Network (MAN)
3. Wide Area Network (WAN)

Let discuss one by one,

Local Area Network

Local Area Network or LAN are those network who covers the small geographical region like home, office, group of building etc. It connects the computer, printer, workstation etc. within a network and also has a low speed of communication lines for connection like twisted pair, co-axial cable or fiber optics. Cost of transmitting data (sending and receiving data) is negligible.

Metropolitan Area Network

Metropolitan Area Network is bigger than Local Area Network because it covers the larger geographical area such as town or city. It also has a high speed of connection microwaves links or co-axial cable. Best example of MAN is Cable television network in many cities. MAN is formed by connecting several LANs which may belongs to various organizations.

Wide Area Network

Wide Area Network (WAN) is a computer network covering very large geographical area, like a country or a continent. WAN is a very high speed communication link like satellite communication, telephones line or Microwaves links.

The cost of sending data from sender to receiver in a WAN is higher than MAN and LAN because of the use of the public communication system such as satellite or telephones lines.
