What is a network?
A network is simply two or more computers linked together. It allows users to share not only data files and software applications, but also hardware like printers and other computer resources .
Most networks link computers within a limited area – within a department, an office or building. These are called Local Area Networks or LAN’s. But networks can share information with someone on the other side of the world as easily as sharing with a person at the next desk. When networks are linked together in this way, they are called Wide Area Networks or WANs.
Networks increase productivity by allowing workers to share information easily without printing, coping, telephoning or posting. They also save money by sharing peripherals such as printers.
