A search of the Internet yields more than 80 different articles ranging from electronic newsletters on the subject to service providers that help set up your system. An example of these articles resides at the Intranet Journal's Web site. This commonality of protocols allows for the exchange and sharing of information literally around the world. An Intranet is that part of a network residing either behind a firewall or completely removed from the Internet. Typically Intranets are corporate-wide information systems protected from outside users and proprietary in their information databases.
Intranets offer some unique new capabilities infeasible on a typical Internet-based system.
The reason you can do some of these more subjective things is because you know the configuration and system requirements for the systems within your company. In fact in many cases evolved standards are implemented to ensure the systems run the selected software for your company. Because you know this information about the configuration and make-up of the systems on your internal networks you can begin to use some specific tools to provide information to your user base. For example on the World Wide Web it's not very feasible to offer information in a solely Microsoft Word format without also providing that information in other formats. Because you are unfamiliar with the tools available to someone browsing your Web pages you need to make sure that your content is available to the lowest common denominator.
