THE DIFFERENCES BETWEEN INTERNET, EXTRANET AND ETHERNET
Extranet:
It is a private network that uses internet protocols,network connectivity, and possibly the public telecommunication system to
securely share part of an organization's information or operations with
suppliers, vendors, partners, customers or other businesses. An
extranet can be viewed as part of a company's Intranet that is extended to users outside the company, usually via the Internet.

Internet:
It is a global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.

Intranet
It is a private network that uses Internet protocols to securely share any part of an organization's information or operational systems within that organization.

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).
