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 difficult as
                                                            it involves a connection all the way to the central node.

                      Tree Topology

                 In  this topology,  nodes are connected  as
                 branches of a tree  where hub acts  as a root
                 node. It is very simple in nature as it is easier
                 to add new or remove the faulty nodes. But its
                 major disadvantage is that if the root node fails
                 to operate, the entire network is inoperable.
                                                                                     Tree Topology



                                                        Mesh Topology
                                                   In this topology, every single node in a network is connected to
                                                   all the other nodes or computers in the network. There is minimal
                                                   chances of breakdown in this topology. This topology is mostly

                                                   used in LANs.
