An intranet is a private network that is restricted to an organization and its employees. It is typically used for internal communication, collaboration, and sharing of information/resources within the organization. Intranets are often built using standard internet technologies such as TCP/IP, HTTP, and web browsers, but they are accessible only to authorized users within the organization. Intranets can include various features such as file sharing, document management, employee directories, email, discussion forums, wikis, and other collaborative tools tailored to the specific needs of the organization. They serve as a centralized platform for employees to access company resources, communicate with colleagues, and stay updated on company news and policies.
