Understanding Networking

A computer network is a group of computers and other associated devices, such as printers, fax machines, and modems, that are connected to one another so they can share resources and information.

A network allows you to:

■Share resources — You and others on the network can share resources, such as a data file or directory, hard disk drive, printer, scanner, or modem.

■Exchange information — You can communicate and exchange information, such as e-mail, with all designated users on the network.

■Provide server support — You can store files and applications in a central location on one PC hard drive, where they can be accessed by any network users who have the proper authorization.

Figure 1 shows a sample network composed of two PCs, a printer, and a hub.
