                   i +   TOPOLOGY

                  The layout or arrangement of computers or nodes in a network is referred to as topology. The
                  choice of topology depends on factors such as cost, flexibility, and reliability. The efficiency and

                  reliability of a network is determined by its structure. In other words, Topology refers to the
                  geometric arrangement of computers or nodes in a network.  Let us learn about them.
                  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 in this topology is very difficult.
                                                                                       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.



                         Ring Topology
                  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.
                                                                                                 Star Topology
