An intranet is a private network accessible only to an organization's employees. It serves as a centralized platform for sharing information, resources, and tools necessary for day-to-day operations. Intranets facilitate internal communication, streamline workflows, and enhance collaboration by providing a single location for employees to access company news, policies, documents, and project management tools.

For instance, a large corporation might use an intranet to host HR policies, training materials, and departmental updates, ensuring all employees have access to consistent and up-to-date information. Intranets help reduce email clutter, improve information retrieval, and support a more connected and efficient workforce.
