3. Intranet services

These are virtually the same as the Internet, but for internal use only.

Some of the services include:

• Email
• File transfer
• Real time chat
• Web pages
• Video and Audio streaming services

Each service requires at least one server to provide the service e.g. Web server and Email servers.

Although it is unlikely that the video and audio services are there for entertainment (unlike the Internet). They can be used to stream business multimedia - for instance video training packages streamed to the students' computer.

The internet itself can usually be accessed through the organisation's firewall. This is quite often restricted though in order to reduce employee 'time-wasting' and to reduce bandwidth costs. For instance many companies block access to social networking sites and sports sites.

The point of an intranet is make people more effective at their work rather as a means of entertainment or socialising.
