COMMUNICATION NETWORK Communication network are large system distributed in wide area which are designed to send and receive information from one computer to another computer and this computers are called host. Network achieves this providing a set of rules which in terms of networking are called protocols. This protocols are set for communication which every host should follow and participate. The network is made up of two types of components: Nodes and
