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 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
                                                         of bluetooth,  Bluetooth 5.0 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

                  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:
                      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.
                      POP3 – Post Office Protocol Version 3: It is an Internet standard protocal that allows e-mail
                      clients to retrieve e-mail messages from an e-mail server.
                      IMAP – Internet Message Access Protocol: 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.
