    REPEATER
                                          A repeater regenerates and retransmits signals in a communication network.

                                          It takes a weakened or corrupted signal and restores it to its original strength
                                          or quality before sending it onward. Repeaters are used to extend the distance
                                          over which data can be transmitted by eliminating signal degradation caused
                                          by distance, noise or interference.

                      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 or
                      more networks.

                                          NETWORKING CABLE

                                          Networking cable, also known as Ethernet cable, is a transmission medium
                                          that  allows  the transfer  of data  between  devices.  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 converts digital signals
                      to analog and the demodulator converts analog signals back into digital.

                                    GATEWAY

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

                         mankind.  We  should  use  it  wisely  and not                 landscapes, data on the Internet
                         misuse  it  to  spread  false news, rumours                  travels across networks in streams
                         or images  that  can disrupt  the  peaceful                            of information.
