Definition of intranet in The Network Encyclopedia.

What is Intranet?

A private TCP/IP internetwork within an organization that uses Internet technologies such as Web servers and Web browsers for sharing information and collaborating. Intranets can be used to publish company policies and newsletters, provide sales and marketing staff with product information, provide technical support and tutorials, and just about anything else you can think of that fits within the standard Web server/Web browser environment.

Internet Information Services (IIS), with its support for Active Server Pages (ASP), is an ideal platform for building intranet applications that can be accessed using a standard Web browser such as Microsoft Internet Explorer.
