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
                                the amplification of the 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 transfer of information between two
            networks.


                                NETWORKING CABLE

                                Networking  cable  also  known as  Ethernet  cable  is  a  transmission medium
                                that allows transporting of information from one place to another. There are
                                various types of networking cables such as coaxial cable, twisted pair cable,
                                and optical fibre cable.


            MODEM

            Modem is a device which 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 the 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 the 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.”
