Therefore network topology is defined as: the schemes of joining a number of computers in the form of a network are called Network Topologies.   There are three commonly used network topologies. These are: Star Topology Ring Topology Bus Topology Star Topology In a star network, each computer is directly connected to the central computer or hub that provides connection points for nodes on the network. In star network, information or data is communicated from one computer to another through hub. Ring Topology In ring network, each computer is connected to two adjacent computer in the form of ring or loop. In ring topology, the last node connects to the first node to complete the ring. In this network, data is communicated in one direction from node to node around the entire ring. Bus Topology In bus network, all computers are connected to a common communication medium or central cable. The central physical cable that connects the nodes is called Bus. In bus topology, a special device called a terminator is attached at the cable's start and end points.
