    PAN (Personal Area Network)

                  PAN is used to establish the communication among the computers within the range of an individual. It
                  can be wired or wireless. PANs typically cover a range of a few meters, making it suitable for personal
                  or home use. It connects devices such as computer, smartphone, tablet, printer, etc.

                  CAN, also known as Cluster Area Network, or Campus Area Network connects two or more LANs that
                  are limited to specific geographical areas. For example, college campus, office building, etc. A campus
                  area network is larger than LAN since it may span in multiple buildings within a specified area.
