A computer is a machine used to manipulate data.
Humans, being communicative creatures, quickly understood why it would
be useful to link computers to each other in order to exchange
information.
A computer network can serve several distinct purposes:
- Sharing resources (files, applications or hardware, an Internet connection, etc.)
- Communication between people (email, live discussions, etc.)
- Communication between processes (such as between industrial computers)
- Guaranteeing full access to information for a specified group of people (networked databases)
- Multiplayer video games
Networks are also used for standardizing applications. The term
groupware
is generally used to refer to tools that let multiple people work over a
network. For example, email and group scheduling can be used to
communicate more quickly and efficiently. Here's a glimpse of the
advantages that such systems have:
- Lower costs, due to sharing data and peripherals,
- Standardizing applications,
- Providing timely access to data,
- More efficient communication and organization.
Today, with the Internet, networks have become more unified. It is
clear, then, that there are several reasons to install a network,
whether for a business or an individual.
