During the 20th century the key technology has been information gathering, processing and distribution. Among other developments we have seen the installation of worldwide telephone networks, the birth and unexpected growth of the computer industry and the launching of communication satellites. These areas are rapidly converging. The merging of computers systems are organized. The old model of a single computer serving all the organization needs is rapidly being replaced by one in which a large number of separate but interconnected computers do the job. These systems are called Computer Networks. A network is a set of devices (often called nodes) connected by media link. A node can be a computer, printer or any other device capable of sending and receiving data generated by other nodes of network. Networks use distributed processing in which a task is divided among multiple computers <<Main Page                                  Next Page>>
