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
                 Wi–Fi   is  the most popular wireless communication technology
                 used for homes, private business LANs and public hotspots.
                 A Wi-Fi enabled device such as a PC, video game console,
                 mobile  phones  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 thus
                 reduces the cost of the network expansion.
                                                                                                 Wi-Fi
                                                             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

                               Bluetooth                of bluetooth, Bluetooth  5.0 technology provides data
                                                        transfer speed up to 2 Mbps.

                 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

                 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 uses 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.

                    TCP/IP—Transmission Control Protocol/Internet Protocol: It is a network protocol that defines how
                   the information or messages are routed from one end of a network to the other.
