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.
                 Wi-Fi

                 Wi–Fi  (Wireless  Fidelity) is  the most popular  wireless
                 communication  technology used for homes,  private

                 businesses, LANs, and public hotspots. A Wi-Fi enabled
                 device, such as a PC, video game console, mobile phone,
                 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, which reduces
                 the cost of network expansion.                                                  Wi-Fi


                                                        Bluetooth

                                                        Bluetooth  is a  technology  that  enables wireless
                                                        communication between low-power consumption devices
                                                        within a short  range  (1 meter,  10 meters, 100 meters).
                                                        The latest version of Bluetooth, Bluetooth 5.0 technology,

                                                        provides data transfer speeds 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, and GPS receivers (Global Positioning
                 System) through a 2.4 GHz short-range radio frequency bandwidth.

                     PROTOCOL

                 Protocol is a set of rules that govern the communication between computers on a network.
                 Certain network protocols and standards must 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:

                    HTTP – Hyper Text Transfer Protocol: It is a set of rules that define how Web pages transfer
                    information like documents, files, images, and videos between computers over the Internet.
                    HTTPS – Hyper Text Transfer Protocol Secure: It is a secure version of HTTP. The information
                    is converted into code to prevent unauthorised access. Nowadays, most websites use the
                    HTTPS protocol instead of HTTP.

                    FTP – File Transfer Protocol: It is a set of rules that allow files to be uploaded and downloaded
                    from other computers via the Internet.
