                   Topology

           Prime (Ver. 2.2)-VIII  factors that determine the type of topology are cost, flexibility and reliability. There
                  Topology refers to the geometric arrangement of computers or nodes in a network. The



                  are five different types of topologies. Let us learn about these in detail.

                   Bus Topology


                  In this topology, all the nodes are connected to a single common path. It is simple and easy
                  to maintain. Additional nodes can be connected at any point along its length. The major

                  disadvantage of this topology is that fault detection is difficult, and a failure in the main

                  cable can bring down the entire network.













                                                              Bus Topology
                   Ring Topology

                  In this topology, all the nodes are connected in a circular path.

                  The messages travel in clockwise or anti-clockwise direction.
                  Any damage to the cable of any node or device can result in
                  breakdown of the whole network.

                                                        Star Topology


                                                      In this topology, central node acts as a hub to which all
                                                      the other nodes are connected. As compared to the bus

                                                      topology, star topology requires more devices and cables.
                                                      The addition of a new node to a star topology is easier
                                                      compared to other topologies such as bus as it involves a

                                                      connection only to the central node.
