6. Why are networks useful?
Some key points
Programs can be shared - software packages can be installed onto the file server and accessed by all individual workstations at the same time.This reduces cost, maintenance and makes upgrades easier.
You can access your work from any workstation on the network. Very handy if you have to change computer every time you go to a different classroom.
Data can be shared by all users at the same time. Many people can access or  update the information held on a database at the same time. Thus information is up to date and accurate.
Users can communicate with others on the network by sending messages and sharing files.
Individual workstations do not need a printer, one high quality printer can now be shared by everyone, thus cutting costs.
Networks provide security. A user must have the correct Password and User ID in order to be able to access the information on the network.
Private areas on the network can be set up that allows each user to store their personal files. The only other person who can access these files is the 'system administrator' who looks after the network.
