    Client/Server Network
                     In a Client/Server network, clients access resources from a central server. The server is responsible
                     for managing all the resources such as files, directories, printers, etc.

                               NETWORK TOPOLOGIES

                     Network topology describes the physical or logical layout of the network, that is, how all the
                     components (such as computers, cables and switches) are interconnected. Common network
                     topologies include:

                       Bus topology: In this topology, all devices are
                        connected to a single central cable called the
                        bus. Data travels in both directions along the
                        bus, but only one device can send data at a time.
                        It is less secure and not very robust - if the main
                        cable fails, the entire network stops working. Bus
                        topology is suitable for small networks that need
                        low speed and have a limited budget because
                        they are inexpensive to set up.

                                                             Star topology: In this topology, all devices are connected
                                                              to  a central hub or switch, which manages  data
                                                              transmission.  It  is  a  robust  topology  because  if  one
                                                              connection  fails, only  that  device  is  affected.  Fault
                                                              detection and isolation are easy in this setup. However,
                                                              if the central node fails, the entire network stop working.

                       Ring topology: In this topology, each device is connected to two
                        other devices, forming a circular pathway for data transmission.
                        It allows high-speed data transfer and is inexpensive to install,
                        but the failure of a single node in the network can cause the
                        entire network to stop working. Troubleshooting is difficult, ans
                        is considered a less secure topology.

                                                                                                  Networks Around Us  15
