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.


                                                        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.





                 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.

                    TCP/IP – Transmission Control Protocol/Internet Protocol: It is a network protocol that
                    defines how information or messages are routed from one end of a network to the other.
                    POP3 – Post Office Protocol Version 3: It is an Internet standard protocol that allows e-mail
                    clients to retrieve e-mail messages from an e-mail server.
