PAN (Personal Area Network)

              PAN is used to establish communication among the computers within the range of an individual. It can
              be wired or wireless. It connects devices such as a computer, smartphone, tablet, printer, etc.

                 The  concept  of  a  PAN  first  was  introduced  by           networks in streams of information.

                 later supported by IBM's Almaden research lab.



              CAN (Campus Area Network)


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

              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 them.

              Bus Topology


              This  topology  connects  all nodes  to a single
              common path. It is simple and easy to maintain.
              You  can  connect  additional  nodes  at  any  point
              along its length. The major disadvantage of this
              topology is that fault detection is very difficult.
