There are various types of networking cables such as coaxial cable, twisted pair cable, and
                  optical fiber cable.

                                        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.






                  Different  types  of  networks  can  be  classified  on  the  basis  of  the    geographical  areas
                  covered. There are five types of networks as follows:


                   LAN (Local Area Network)

                  LAN is a short form of Local Area Network. It is a
                  digital communication system that interconnects
                  a large number of computers and other peripheral

                  devices within a radius of less than 1 km. This type of
                  network is usually preferred for a smaller area such
                  as a residence, school, laboratory, university campus
                  or office building. By using the LAN network, users

                  can exchange data and messages in the easy and fast
                  way. Cables and communication devices are used to                                            Server
                  connect computers to the LAN.                                             Local Area Network


                   MAN (Metropolitan Area Network)

                  This  network consists of two or more local  area  networks together  that  usually  spans
                  several buildings in the same city or town.
