    NETWORK ARCHITECTURE

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

                      network architectures as follows:
                           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

                      It is a network in which one computer is designated as the server and all the other computers

                      connected on the network are called the clients. The clients can request for the services from the
                      server. This is called the client-server network.

                                                                Internet
                                              Clients

                                                                                                  Server

                                                               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.
