Infrared Communication: The infrared light transmits data through the air and can propagate
                    throughout  the room by bouncing  off  surfaces but  will  not penetrate  walls.  This type  of
                                        transmission  uses  infrared light to  send data.  Infrared  light is similar  to

                                        normal lights, except that these have a longer wavelength. Therefore, they
                                        are not visible to us. You can see the use of this type of transmission in
                                        everyday life: TV remotes, automotive garage doors, wireless speakers, etc.
                    All of these make use of infrared light for transmission.




                            PROTOCOLS

                  Protocol is a set of rules that governs 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. Some  of  the  Internet  protocols  for
                  addressing the data transmitted over the Internet are here.

                  HYPERTEXT TRANSFER PROTOCOL (HTTP)

                  HTTP stands for Hypertext Transfer Protocol. It is the set of rules or protocols that govern the
                  transfer of hypertext (webpages) between two or more computers using a standard language
                  HTML. It is the primary protocol used to exchange data between a web browser and a website.


                  HYPERTEXT TRANSFER PROTOCOL SECURE (HTTPS)
                  HTTPS  stands  for  Hypertext  Transfer  Protocol Secure. It is an extension of Hypertext Transfer
                  Protocol used for secure communication over a network. It establishes a secure connection by
                  establishing an encrypting link between the browser and server, hence maintaining data integrity
                  by encrypting the data.


                  TRANSMISSION CONTROL PROTOCOL/INTERNET PROTOCOL (TCP/IP)

                  TCP/IP stands  for Transmission  Control  Protocol/Internet Protocol.  It enables  computers  over
                  a network to communicate with each other. A set of LANs and WANs uses the TCP/IP suite to

                  communicate with each other.

                  FILE TRANSFER PROTOCOL (FTP)

                  FTP stands for File Transfer Protocol. It is a part of the TCP/IP protocol suite and enables files to be
                  transferred between computers.


                  INTERNET MESSAGE ACCESS PROTOCOL (IMAP)
                  IMAP stands for 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.
