Bluetooth
                                                        Bluetooth is a technology that enables wireless communication
                                                        between 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, GPS receivers (Global Positioning System)
                 through 2.4 GHz short range radio frequency bandwidth.


                        PROTOCOL
                                                                                   Just as red blood cells carry
                 Protocol is a set of rules that governs the communication         oxygen and white blood cells
                                                                                   fight infections, data packets
                 between the computers on a network. Certain network             deliver information while security
                 protocols  and  standards must  be  followed  in  order           protocols protect a network.

                 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 documents, files, images, videos 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.

                    File Transfer Protocol (FTP): It is a set of rules that allows file uploading and downloading from the
                   other computers over the Internet.

                    Transmission Control Protocol/Internet Protocol (TCP/IP): It is a network protocol that defines
                   how the information or messages are routed from one end of a network to the other.
                    Post Office Protocol Version 3 (POP3): It is an Internet standard protocol that allows e-mail clients
                   to retrieve e-mail messages from an e-mail server.
                    Internet Message Access Protocol (IMAP): It is an e-mail protocol that stores e-mail messages on
                   a mail server and allows the user to view, access and manipulate the messages on the mail server
                   from their computer.
                    Simple Mail Transfer Protocol (SMTP): It is an e-mail protocol for sending e-mail messages across
                   the Internet.
