A network is a system where a chain of computers are linked with each other so as to transfer data electronically.

Not only computers and communication devices, a network with the help of advanced architecture, helps to connect varied type of equipments in order to communicate information in the most convenient way. OSI whose full form is ISO Open Systems Interconnection and SNA whose full form is IBM’s Systems Network Architecture, are the popular architectures known. (Shelly and Rosenblatt, 2009; Steve, 2001 ). There are two network types, one is LAN which is called Local Area Networks and another is Wide Area Networks.

LAN basically connect two or more computers, printers and file servers within a limited area such as in office area, or in a college or school by means of cable and wires , which enable the computer system to have an access on a common set of files. Users with the help of LAN operating system can communicate with each other and share printers and storage equipments and can also access the centrally located processors. LAN can act as transfer points if two similar architectures are linked by bridges.

Data can get converts across systems if LAN with different architectures are linked through gateways.(Shelly and Rosenblatt, 2009; Steve, 2001 ). Wide Area Networks help to link small networks and computers to large networks over a wide geographical area which includes different continent also. The network is connected through fibres, satellites or else a device commonly used called modem. Internet is such a Wide Area Network which connect users world wide through a collection of networks and gateways.
