    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.

                          Tree Topology
                     In this topology, nodes are connected as branches of a
                     tree where hub acts as a root node. It is scalable as it

                     is  easier  to  add  new or remove  the  faulty  nodes.
                     However, 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 are minimal
                                                       chances of network failure in this topology due to redundant
                                                       connections.
