Network Topology is the representation of a network arrangement, consisting of several nodes i.e. sender and receiver nodes, and the lines connecting these nodes. Types of Network Topology : Let us look at the type of Network Topologies available. P2P Topology : Point-to-point topology is the easiest of all the network topologies. In this method, the network consists… Read More »
