i +   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

                  It refers to Wireless Fidelity, which lets you connect to the
                  Internet without any wired connection from your PC. It is a

                  popular form of wireless connection as it does not require
                  cables.
                  It can be used to get connected through a variety of devices
                  like laptops, digital cameras, smartphones, gaming consoles,
                  etc. To connect to a Wi-Fi network a hotspot is required.

                  The hotspot acts as a gateway to the Internet, you need to
                                                                                                  Wi-Fi
                  connect to hot-spot to be able to connect to the Internet.
                                                      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 facilitate for different
                                                      devices to communicate with each other when they are in a
                                                      specified 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,  GPS receivers  (Global  Positioning System)
                  through 2.4 GHz short range radio frequency bandwidth.

                   i +   PROTOCOL

                  Protocol is a set of rules that governs the communication between the computers on a network.
                  Certain network protocols and standards are to be followed in order to ensure that your computer

                  can communicate with another computer over a network.
                  Different types of protocols used for different operations on the Internet are as follows:
                  •  Hypertext Transfer Protocol (HTTP): It is a set of rules that defines how the Web pages
                     transfer information like document, file, image, video between computers over Internet.

                  •  Hypertext Transfer Protocol Secure (HTTPS): It is secure version of HTTP. The information
                     is converted into code to prevent unauthorised access. Nowadays, most of the websites use
                     the HTTPS protocol instead of HTTP.
