Intranet

Intranet
An Intranet is a private network within an organization that uses Internet technologies to share information and resources securely. It's the digital backbone of modern organizations — powering internal communication, document sharing, collaboration, and productivity.
Introduction
While the Internet connects the entire world, the Intranet connects the people within a single organization. Every company, university, and large institution uses an intranet to manage internal operations, communication, and collaboration.
An intranet uses the same technologies as the Internet — like TCP/IP, HTTP, and web browsers — but is restricted to authorized users only. It's like having your own private Internet just for your organization.
Real-Life Analogy
An Intranet is like a private club or member-only community. Only members (employees) can enter, use the facilities (resources), and interact with each other. Outsiders can't access it — keeping everything secure and organized.
What is Intranet?
