NETWORK ARCHITECTURE

                  The network architecture defines the overall design of a 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 the data. In this architecture, each
                  computer is considered to have equal responsibilities and can
                  acts like a server  to the  other  computers  in the  network.  It
                  works well in small environment.                                           Peer-to-Peer Network

                                                      Client-Server Architecture


                              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 services from the
                        Client-Server Network         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
                  us to deploy local area networks without wires thus reduces the cost of the               Wi-Fi
                  network expansion.
                  Bluetooth

                  Bluetooth  is a technology that  enables wireless communication between  a
                  low-power  consumption devices within a short range  (1 meter, 10 meters, 100
                  meters). It facilitates communication between  different devices when they are
                  within a required range. The latest version of Bluetooth, Bluetooth 5.4 technology
                  provides data transfer speed up to 2 Mbps.                                                 Bluetooth

                  It provides a way  to connect  and  exchange  information  between  devices  such  as  mobile
                  phones, telephones, laptops, printers, personal computers, Global Positioning Systems (GPS)
                  receivers through 2.4 GHz short range radio frequency bandwidth.

                    GPS is a  satellite-based navigation  system which  is used to  identify  the  geographical
                    location of an object.
