What distinguishes the Internet from an intranet?

An intranet is specifically designed for internal use within an organization. It provides a secure environment where employees can communicate, share documents, and access company resources without exposing sensitive information to the outside world. This restricted access is what primarily differentiates an intranet from the Internet, which is a global communication network accessible by anyone with an internet connection.

The Internet serves as a vast network that connects millions of private, public, academic, business, and government networks. It allows for worldwide communication and data exchange. While options that refer to external communication methods or public access to databases may highlight aspects of Internet functionality, they do not capture the essence of what an intranet represents.

By focusing on internal sharing, the answer accurately reflects the specific purpose of an intranet compared to the broader framework of the Internet.
