PAN (Personal Area Network)

                 These are privately owned networks. PAN is used to establish the communication amongst the
                 computers within the range of 20 to 30 feet. It can be wired or wireless.

                   The concept of a PAN was first introduced by Thomas Zimmerman at M.I.T.'s Media Lab. It
                   was later supported by IBM's Almaden research lab.


                 CAN (Campus Area Network)

                 CAN, also known as Cluster 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.

                     TOPOLOGY

                 Topology refers to  the geometric arrangement  of  computers or  nodes  in  a network.  The
                 factors that determine the type of topology are cost, flexibility and reliability. There are five
                 different types of topologies. Let us learn about these in detail.
