2  LAN ADVANTAGE  Workstations can share peripherals devices like printers. Cheaper that providing a printer for each computer.  Workstations do not necessary need their own hard disk or CD-ROM drives which make them cheaper to buy than stand-alone PC.  User can save their work centrally on the network’s file server. This means that they can retrieve work from any workstation on the network.  They don’t need to go to the same workstation again. DISADVANTAGE Special security measures are needed to stop the users from using programs and data that they should not have accessed to. Network are difficult to set up and need to be maintained by skilled technicians. If the file servers develop a serious fault, all the users are affected, rather than just one users in the case of a standalone machine. It needs to be on all the time. 2
