The Interactive Glossary: Defining the Net
Intranet

An intranet is basically an internal Internet designed to be used within the confines of a company, university, or organization. What distinguishes an intranet from the freely accessible Internet is that an intranet is private. Until recently most corporations relied on proprietary hardware and software systems to network its computers, a costly and time-consuming process made more difficult when offices are scattered around the world. Even under the best of conditions, sharing information among different hardware platforms, file formats and software is not an easy task. By using off-the-shelf Internet technology, intranets solve this problem, making internal communication and collaboration much simpler.
