Having a computer network enables you to combine skills of different people and the power of different equipment, regardless of the physical locations of the people or the equipment. A well-designed computer network enables users to instantaneously and effortlessly collaborate and view, change and exchange information. Freedom to Choose the Right Tool .
Different tasks require different kinds of computers.
Cost-Effective Equipment Sharing . Without a network your office would need to buy many inexpensive, low-quality printers or other computer peripherals for each workstation, which would sit idly most of the time and may not be entirely appropriate for every task of each user. With a network you can buy a small number of top-quality printers or other peripherals, use them to their full potential, and use the peripheral which is best suited to the individual task, all at a significantly lower overall cost. Flexible Use of Computer Power . A network will allow users to tap otherwise unused processing power on their network in order to dramatically speed up their desktop applications or execute many tasks at the same time.
