Tree Topology

                  In this topology, nodes are connected as branches
                  of a tree, where the hub acts as a root node. It is
                  very simple in nature, as it is easier to add new or
                  remove faulty nodes. The major disadvantage  of
                  'tree  topology'  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 chance of breakdown in this topology. This topology
                                                   is mostly used in LANs.

                      NETWORK ARCHITECTURE

                  The network architecture defines the overall design of the computer network. There are two
                  types of network architectures.

                                                         Peer-to-Peer Network

                                                         It is a network of two or more computers that use the same
                                                         type of program to share data.  Each computer is considered
                                                         to have equal responsibilities and acts like a server to the
                                                         other  computers in the network.  It works well in a small
                                                         environment.

                           Peer-to-Peer Network
                  Client-Server Network

                  It is a network in which one computer is designated as the server and all the other computers
                  connected to the network are called the clients. The clients can request services from the server.
