intranet

An intRAnet differs from the intERnet, by being quite literally, inside an organization. Intranets are separated from the internet by firewalls and other security measures. In the most broad sense of the term, intranet applies to the whole IT network, but more specifically it applies to software platforms or applications that are specifically used for collaboration, knowledge management, communication and planning. Most web based services can be deployed "behind the firewall" for better security.
