Advantages of connecting computers in a LAN
-           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 networkfs file server. This means that they can retrieve their work from any workstation on the network. They donft 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.
Disadvantages of connecting computers in a LAN
-           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.
