Hub or Switch

                                       Hub or Switch is a hardware device that has various boxes to which the
                                       computers, printers and other networking devices are connected. The main
                                       function of a hub is to direct information around the network and facilitate
                  Hub or Switch        communication between all the connected devices.

            Router

            Router is a networking device used to connect and facilitate transfer of data in
            the form of packets between two network. It finds best route for data packets
            over the network.  It is located at the gateways where two networks connect.


                          Modem                                                                      Router

                          It stands for  MODULATOR–DEMODULATOR. It is a hardware device that allows a
                          computer to send and receive data over a telephone line. It converts data from digital
                          to analog and vice versa. The process of converting analog signals to digital signals is
                          called demodulation. The process of converting digital signals to analog signals is called

               Modem      modulation.

            Networking Cable

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

                                          Gateway


                                          Gateway is a network device that allows to 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.
