All computers on the network can use any printer on the network. When properly configured, networked computers can share applications. For example, users throughout your art department can access programs like CorelDraw, Illustrator, PhotoShop, and QuarkXpress. If your computers are networked, you don't necessarily need a separate installation of Illustrator on every computer in the department. Consider how much hard disk space will then be available for other applications, file backups, and other computing procedures that use large amounts of space.
Networked computers are without equal in file sharing and transferring.
If you answered yes to these questions, then you need a network. A properly configured network enables users at any computer on the network to view and access any file on all other computers on the network. File security is another advantage of having networked computers. A good network uses an operating system that controls access by workstation, drive, folder, and file. Employees can be assigned different levels of access to these files.
