              devices within a short range (1 meter,  10 meters,  100 meters).  It facilitates 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.

                    PROTOCOL

              A 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:

                   HTTP - Hyper Text Transfer Protocol: It is a set of rules that defines how the Web pages transfer
                 information like document, file, image, video between computers over Internet.

                   HTTPS - Hyper Text Transfer Protocol Secure: 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.

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