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.




                                                   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.



                  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.

                      WIRELESS NETWORKING TECHNOLOGY

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