Tree Topology

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

                  i +  NETWORK ARCHITECTURE

                 The network architecture defines the overall design of the computer network. There are two
                 types of network architectures.
                 Peer-to-Peer Network

                 An alternative to  the  client-server  approach  is the  peer-to-
                 peer approach. There are no dedicated servers. All computers
                 are equal and can share their resources to be used by others
                 and are therefore known as peers. This network is more cost
                 effective and requires low maintenance and works well in a
                 small environment.
                                                                                           Peer-to-Peer Network
                 Client-Server Network

                 This is the most efficient network architecture which consists of two parts: client system and
                 server system. 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. This is
                 called the client-server network. The client does not share any of its resources but requests for
                 the server’s content.
