                        How do you think the Internet would be different if we didn’t have network protocols to help devices
                        communicate with each other?

                             TYPES OF COMPUTER NETWORKS

                      Computer networks can be categorised based on their size and architecture.

                      ON THE BASIS OF SIZE

                      There are various types of networks depending on the size and expanse
                      of the network:

                          Local Area Network (LAN): A LAN covers a small geographic area,
                         like a home, school or office, mostly within a building or campus.
                         Devices  in a  LAN are usually  connected  using Ethernet  cables
                         or Wi-Fi.
                                           Advantages                                     Disadvantages

                          High speed and low latency                       Limited to a small area

                          Cheaper setup costs                              Risk  of unauthorised  access  if not  properly
                                                                           secured
                          Easy to share files and resources like printers  Network problems may affect all connected
                                                                           devices

                          Metropolitan Area Network (MAN): This network connects two or more local area networks to cover
                         a larger area than a LAN but smaller than a WAN, such as a city or a large campus.

                                                                    Branch B

                                                                                           Branch C
