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 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 a small environment.

                       Client-Server Network                                                 Peer-to-Peer 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. The server processes the request and sends back the requested information. This is called
                  the client-server network.

                                              Clients


                                                                                          Server

                         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. Two common types
                  of wireless technologies are Wi-Fi and Bluetooth.

                       Wi-Fi
                  Wi–Fi is the most popular wireless communication technology used in
                  homes, private business LANs and public hotspots. A Wi-Fi enabled
                  device such as a PC, video game console, mobile phones or MP3                Wi  Fi
                  player can connect to the Internet when it comes within the range
                  of a wireless network. Wi-Fi allows us to deploy local area networks
                  without wires and thus reduces the cost of the network expansion.

                                                                                                    WiFi
                                                                                                      Wi-Fi
                                                                                                  Electronic Devices
