=The internet and intranet=

Characteristics:
An intranet is built from the same concepts used for the Internet. An intranet can be used as a private version of the Internet, or as a private part of the Internet only for a school or company/organization. Intranets are generally restricted to employees of the organization. An organization's intranet does not have to provide access to the Internet. When access is provided it is usually through a network gateway.
