Network users are usually required to identify themselves before they can gain access to the information on a network. This is known as logging on. Each user must enter a personalized user name and password to access a network. By keeping this information secret, users can prevent unauthorized people from accessing the network.

Sharing Information
You can use a network to share information with other people. Information can be ant form of data, such as a document created in a word processing program, a picture drawn in an imaging application or information from a database. Before networks, people often used floppy disks or any other storage device to exchange information between computers, which was a slow and unreliable process. With networks, exchanging information between computers is quick and easy.

Sharing Resources

Computers connected to a network can share equipment and devices, called resources. The ability to share resources the cost of buying computer hardware. For example, instead of having to buy a printer for each person on a network, everyone can share one central printer.

Sharing Programs

Networks allow people to access programs stored on a central computer, such a s a spreadsheet or word processing program. Individuals can use their own computers to access and work with the programs. By sharing a program, a company can avoid having to install a copy of the program on each person's computer.
