    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.

                             TYPES OF NETWORKS

                      Different types of networks can be classified on the basis of geographical area they cover. There are
                      five types of networks as follows:

                           LAN (Local Area Network)
                      LAN stands for 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 connect computers to the LAN.

                                                                 Workstation

                                                                                    Server

                                                                   Local Area Network

                                         Imagine, computer networks as highways in the sky. What vehicles would travel on
                                         these highways and what destinations would they reach?

                           MAN (Metropolitan Area Network)
                      This network consists of  two or more local area networks or campus area networks together and
                      usually spans several buildings in the same city or town.
