Intranet

Intranet is a private miniature internet, usually belonging to a single company or organization, connecting the organization’s computers together while (usually) restricting access from the internet proper.

Intranets can still be world-wide, use- TCP/IP- protocols, and be structured as a collection of networks but the greatest difference is that access is limited to a set of authorized users using firewalls and other mechanisms.
