                    WHAT IS A NETWORK?


                 In  computer  terms,  a  network  is  defined  as  a  collection  of  computers  and  devices  that  are
                 interconnected,  allowing  users  to  easily  communicate  and  share  important  files,  software,
                 resources,  and  information as needed.  Each  computer in a network  is called a node.  The
                 computers in the network may be linked through a cable, hub, switch, NIC (Network Interface
                 Card), modem, or router.
