 To build up a communication between two or more being is called network. Thus the processing of making communication between to more computer by cable, modem or satellite is called networking. In both decade by mini and mainframe computer first networking process was started on. Later on in the starting of 80th decade networking process started on through personal computer(PC). It is no need to say that in personal computer only one user can used it at the sane time. Due to networking in PC more than one user can use one computer at the same time. Again one user can use more than one computer at the same time. In short we can say that because of networking the entire computer computer under network automatically come under the same system. That means processing unit of all computers under same network being inter-connected is made into three categories
