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’s file

server. This means that they can retrieve their work from

any workstation on the network.

• They don’t 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

Disadvanges

• Special security measures are needed to stop users from

• 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.
