What is an intranet?

An intranet is defined as a private network that uses Internet technologies. This means that while it employs the same technological framework as the public Internet (such as protocols, IP addresses, and web browsers), it is specifically designed for use within a single organization or institution. Unlike the public Internet, which is accessible by anyone with a connection, an intranet restricts access to authorized users, which enhances security and privacy.

Intranets typically serve to facilitate communication, collaboration, and information sharing among employees. They can host internal resources such as project management tools, databases, and corporate communications that are tailored to the needs of the organization, ensuring that sensitive information remains secure and accessible only to authorized personnel.

The other options do not accurately describe an intranet: a public network for worldwide sharing refers to the Internet, a global database of information implies a more external, communal system rather than a localized private network, and a type of internet connection for mobile devices pertains more to connectivity rather than the concept of a private network itself.
