1. Networks

   • A network is 2 or more computers connected together so they are able to share resources and communicate.
   • Advantages
     • You can log onto any workstation with a network
       • All of the files and folders can be backed up from the file server each evening.
         • Anti-virus software can also be run centrally and can check every workstation on the network at the same time.
           • Each person can only see their own files and folders. Keeps work safe.
   • Disadvantages
     • If a virus is introduced to the network it will easily spread to the other workstations.
       • If the file server fails then no one on the network can access any files or folders.
         • As more users log onto network and request files, the network can start to slow down.
           • Not cheap to build network.

2. LAN

   • Local area network
