LAN Advantages: Workstations can share peripheral devices like printers. This is cheaper than buying a printer for every workstations. Workstations do not necessarily need their own hard disk or CD-ROM drives which make them cheaper to buy than stand-alone PCs. User can save their work centrally on the networks file server. This means that they can retrieve their work from any workstation on the network. They dont need to go back to the same workstation all the time. Users can communicate with each other and transfer data between workstations very easily. One copy of each application package such as a word processor, spreadsheet etc. can be loaded onto the file and shared by all users. When a new version comes out, it only has to be loaded onto the server instead of onto every workstation.LAN Disadvantages:Answer: Special security measures are needed to stop users from using programs and data that they should not have access to; Networks are difficult to set up and need to be maintained by skilled technicians. If the file server develops a serious fault, all the users are affected, rather than just one user in the case of a stand-alone machine.
