REPEATER
                                      The Repeater  regenerates  the  input  signals  and amplifies  only the  desired
                                      signals reducing the noise component of the signals. It is used at places where

                                      amplification of input signal is necessary.


                  ROUTER

                  A router is used when multiple devices need to connect to the Internet
                  using the same IP. It works on the network layer.  In other words, it is
                  used to connect and facilitate the transfer of information between two

                  networks.


                                      NETWORKING CABLE
                                      Networking cable also known as Ethernet cable is a transmission medium that

                                      allows to transport information from one place to another place. There are
                                      various types of networking cables such as coaxial cable, twisted-pair cable,
                                      and optical fiber cable.


                  MODEM
                  A  modem  is a  device  that  is  used  to  transmit  data  over a  network.  It  is

                  attached to computers that can convert digital signals (to be transmitted over
                  telephone lines) to analog (continuous electrical waves) and convert analog
                  signals to digital signals at the receiving end.
                  Modem is the short form of Modulator-Demodulator where the modulator can convert digital
                  signals to analog and the demodulator does the opposite.



                                 GATEWAY

                                 A gateway  is a network device  that  allows  data  to flow  between  two different
                                 networks which may use different protocols. It collects data that is to be sent from
                                 one  computer, converts it  into  small packets  and then sends  them  to  another
                                 computer.

                              “Network has proved to be a boon for mankind. We should use it wisely and
                              not misuse it to spread false news, rumours, or images that can disrupt the
                              peaceful atmosphere around us.”
                                                                                      -Mr Techie
