A computer network can serve several different purposes:
- The sharing of resources (files, applications or hardware, internet, etc…)
- Communication between people (email, live chat, etc…)
- The communication (between industrial computers for example)
- The guarantee of uniqueness and universality of access to information (databases, networks)
- The multiplayer game
The networks also help standardize the applications, usually referred to as groupware tools to qualify for multiple people to work collaboratively. For example, email and group calendaring can communicate more effectively and more quickly. Here is an overview of the benefits of such systems:
- Reduced costs through sharing data and peripherals,
- Standardization of applications,
- Access to data in time,
- Communication and organization more effective.
Today, with internet, there is a unified network. Thus, the interests of the establishment of a network are numerous, be it a company or an individual.
