Network Interface Card (NIC)

              NIC is an expansion card that enables a computer to access a network. It allows the
              computer to connect to a network via wired or wireless means.

                                         Hub or Switch                                                         NIC

                                         Hub or  Switch is a hardware device  that has various ports to which  the
                                         computers, printers, and other networking devices are connected. The main

                    Hub or Switch        function of a hub is to direct information around the network and facilitate
                                         communication between all the connected devices.
              Router

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

                            Modem

                            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 digital signals to analog signals is called modulation.
                            The process of converting analog signals to digital signals is called demodulation.

              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 the data to flow between two different
                                      networks, which may use different protocols. It collects data that is to be sent
                                      from one computer, then sends it to another computer. It acts as a gatekeeper,
                                      performing functions like spam filtering, virus scanning, etc. of the data entering
                      Gateway
                                      a network.

              TYPES OF NETWORKS

              Different types of networks can be classified on the basis of the geographical area they cover.
              There are five types of networks. Let's learn about them.
