Campus Area Network (CAN):  A  CAN  is  a  network
                                Hostel                  that  connects  multiple  LANs  within  a  university  campus,
                                                        corporate  campus,  or  industrial  park.  CANs  provide

                                             Lab        high-speed  connectivity  and  centralised  management  of
                  College
                                                        resources across multiple locations.

                    Local  Area Network  (LAN):  When the computers are
                    interconnected within a limited distance then it becomes a
                    Local Area Network (LAN). This relatively small area can be a
                    single room, a floor, the school buildings or an office building
                    or a factory. LAN can be wired using Ethernet or optical fiber
                    cables, or wireless using Bluetooth or Wi-Fi technology.
                                                                                                              Server

                    Metropolitan Area Network (MAN): When the computers are interconnected within the
                    same city, such as the branches located at different places in the same city then it becomes a
                    Metropolitan Area Network(MAN). It is typically owned and operated by a single entity such
                    as a government body or large corporation. For example, local libraries, cable TV networks,
                    and branches of the same school or office within a city, etc. It spans a physical area larger than
                    a LAN but smaller than a WAN.

                    Wide Area Network (WAN): A WAN spans a larger geographical area, often connecting
                    LANs across cities, countries, or continents. The Internet is the largest WAN, enabling global
                    connectivity and communication.
