                         Covers large geographical areas                  Expensive to set up and maintain

                         Connects multiple LANs and MANs                  Slower speed and high latency
                         Facilitates communication across the world       Difficult to troubleshoot and manage

                       Personal Area Network (PAN): A PAN is a small network
                        that connects devices in close proximity to an individual,

                        typically within a range of a few meters. PANs use wireless
                        technologies such as Bluetooth and Wi-Fi to connect devices
                        like smartphones, laptops, tablets and wearable devices
                        (like smartwatches). PANs are generally used for personal
                        purposes and allow easy data transfer between devices,
                        such as syncing files or connecting wireless headphones to
                        a phone.

                       Campus  Area  Network  (CAN): CAN (also known as Cluster  Area Network) connects
                        multiple buildings or facilities within a specific area, such as a university campus, corporate
                        office  campus  or industrial  complex.  It  provides  high-speed  connectivity  for inter-building
                        communication and resource sharing.
