Chapter Profile
                  WAN (Wide Area Network)
                  It is a digital communication system that interconnects a large number of computers over a wide
                  geographical area. This network may operate on a worldwide or nationwide basis. In such type of

                  network, there may not be a physical connection between computers. Transmission mediums such

                  as telephone lines, microwave links, and satellite links can be used in a WAN.

                  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.

                  CAN (Campus Area Network)

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