Authorized users can access data stored on other computer on the network. In a computer network different resources can be shared among different users such as printer, scanners and plotters etc.

An organization can save a lot of money by sharing different resources such as printer, scanner and plotter over a network. Without the facility of network these resources are attached separately with each computer which is very costly for an organization. Similarly, different software can be shared on the network instead of purchasing a separate copy of software for each user. Data can be easily managed by using computer network.
