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.
