Interconnected networks use the Internet Protocol. There are three variants of internetworks such as Intranet, Extranet and Internet.

  1. Intranet – An intranet is a set of networks, using the Internet Protocol and IP-based tools such as web browsers and file transfer applications which are under control of a single administrative entity. The administrative entity closes or contact to all but specific authorized users. In other words, an intranet is the internal network of an organization. A large intranet network will have one web server to provide users with organizational information.
  2. Extranet – An extranet is a controlled private network which allows access to vendors, partners, and suppliers or an authorized set of customers. It is a part of intranet in which selected people outside the company can use.
  3. Internet – Internet is the largest network in the world. It consists of a worldwide interconnection of academic, governmental, private and public networks which is based upon the networking technologies of the Internet Protocol Suite.
