Which of the following best describes the role of an intranet?

The role of an intranet is best described as a private network for internal communication. An intranet is designed for use within an organization and is not accessible to the general public. It enables employees to connect, share information, and communicate effectively within the confines of the organization's network.

Intranets often include tools such as internal websites, communication platforms, and file-sharing services, which enhance collaboration among staff. They are used to disseminate company news, policies, and other resources, essentially creating a secure environment for information exchange that is specific to the organization.

The option related to public access refers to networks that are open for anyone to join, which does not reflect the nature of an intranet. Similarly, while an intranet may have connectivity options to the internet, its primary purpose is distinctly separate, focusing on internal functionalities rather than external connections. A network exclusively for vendors also does not capture the broad internal communication aspects that an intranet supports, as its purpose is more circumscribed and would not encompass the full scope of an organization’s internal needs.
