CAN (Campus Area Network)

                 CAN, also known as Cluster Area Network, connects
                                                                                               Hostel
                 two  or  more  LANs  that  are  limited  to  specific
                 geographical areas, for example, college campuses,                                        Lab
                                                                                  College
                 office buildings, etc. A campus area network is larger
                 than a LAN since it may span multiple  buildings
                 within a specified area.                                                      Library

                     TOPOLOGY

                 Topology refers to the geometric arrangement of computers or nodes in a network. The factors
                 that determine the type of topology are cost, flexibility, and reliability. There 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 very difficult.


                 Ring Topology

                 In this topology, all the nodes are connected in a circular path.
                 The messages travel in a clockwise or anti-clockwise direction.
                 Any damage to the cable of any node or device can result in the
                 breakdown of the whole network.




                                                     Star Topology

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



                                                                                         Computer Networking     119
