An extranet is defined as a private network of computers that makes use of internet protocols, network connectivity and a telecommunication system in order to share the information or operations related to the company and its stakeholders.

On the other hand, an Intranet is also a private network of computers. It also makes use of internet protocols and network connectivity to share organization wide information and processes with it employees.

Thirdly, an internet is a world wide or global system. It consists of interconnected computers. Data is interchanges through data packets using TCP/IP suite. It is also known as network of networks. This is because people make use of it for connecting individual and organization wide network.

An intranet is a private computer network that uses Internet technologies to securely share any part of an organization's information or operational systems with its employees. Sometimes the term refers only to the organization's internal website, but often it is a more extensive part of the organization's computer infrastructure and private websites are an important component and focal point of internal communication and collaboration.
An intranet is built from the same concepts and technologies used for the Internet, such as client-server computing and the Internet Protocol Suite (TCP/IP). Any of the well known Internet protocols may be found in an intranet, such as HTTP (web services), SMTP (e-mail), and FTP (file transfer). Internet technologies are often deployed to provide modern interfaces to legacy information systems hosting corporate data.
An intranet can be understood as a private version of the Internet, or as a private extension of the Internet confined to an organization. The first intranet websites and home pages began to appear in organizations in 1990 - 1991. Although not officially noted, the term intranet first became common-place inside early adaptors, such as universities and technology corporations, in 1992.
Intranets differ from extranets in that the former are generally restricted to employees of the organization while extranets may also be accessed by customers, suppliers, or other approved parties. Extranets extend a private network onto the Internet with special provisions for access, authorization and authentication (see also AAA protocol).

The internet is worldwide, and can be accessed from any computer with an internet connection.    The Intranet is like local internet, i.e. Can only be accessed on a web of computers, like a business, or a school. Things on the intranet can sometims be accessed via the internet though.    The Extranet is a portion of an organisations Intranet that is made accessible to authorised outside users without full access to entire organisations' intranet.
