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 or remove the faulty nodes.
                                                     But its major disadvantage is that if the root node fails to

                        Tree Topology                operate, the entire network is inoperable.
            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.

                NETWORK ARCHITECTURE                                                          Mesh Topology

            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 uses the same
            type of program to share the 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 small environment.
                                                                                       Peer-to-Peer Network
                                                Client-Server Network


                        Internet                It is a network in which one computer is designated as the
               Clients
                                                server and all the other computers connected on the network
                                                are called the clients. The clients can request for the services
                  Client-Server Network         from the server. This is called the client-server network.
                WIRELESS NETWORKING TECHNOLOGY


            In a wireless networking technology, no wires or physical media is used for connecting computers.
            It uses electromagnetic waves like infrared, microwave and radio waves for transmission of the
            data. The choice of the technology depends on the distance and speed of transmission. There
            are two types of wireless technologies named Wi-Fi and Bluetooth.
            Wi-Fi

            Wi–Fi is the most popular wireless communication technology used for homes,
            private business LANs and public hotspots. A Wi-Fi enabled device such as a

            PC, video game console, mobile phones or MP3 player can connect to the
            Internet when it comes within the range of a wireless network. Wi-Fi allows
                                                                                                      Wi-Fi
            us to deploy local area networks without wires thus reduces the cost of the
            network expansion.
