Difference between internet and intranet?
16 Mar 07
The term "intranet" is somewhat misleading conceptually, because it invites a contrast to the term "Internet." The real contrast is with the World Wide Web--an important distinction, because "Internet" focuses on physical and technical networks, while the Web focuses on the set of content accessible on that physical and technical infrastructure. When I coined the term "IntraNet" at Amdahl Corp. in the summer of 1994, it did have the connotation of an internal Web rather than just an internal Internet. In fact, the term we used internally before this was the too-cumbersome "Enterprise-Wide Web." So, while the ambiguity of "intranet" was apparent even back then, for lack of a better alternative, it caught on. In the early days, I defined an intranet as "An infrastructure based on Internet standards and technologies that supports sharing of content within a limited and well-defined group." The "infrastructure" referred to the organizational and management infrastructure that created, managed, and shared the content. The only technical constraint was that the physical network be based on the Internetworking Protocol (IP). You might notice that this definition encompasses what we call extranets today, because the defining factor is a "limited and well-defined group," and does not specify any official organizational affiliation. The Web, in contrast, is an unlimited group. Today I think of intranets, extranets, and the Web as collections of content. An intranet is a set of content shared by a well-defined group within a single organization. An extranet is a set of content shared by a well-defined group, but one that crosses enterprise boundaries. These access distinctions are important, because Web-based content uses the same technical infrastructure regardless of access decisions. This means it is much easier to change access to specific content than it was in the old proprietary world,where making something more widely available often entailed a major conversion effort. As technical infrastructure becomes less of a barrier to accessing specific content, it becomes important to pay attention to how, or if, we want to restrict access. The terms "intranet" and "extranet," as imperfect as they are, provide us with conceptual and pragmatic tools for discussing to whom we want to make specific content available. These terms may continue to evolve in meaning. For now, a set of content accessed by members of a single organization is an intranet, even if the information travels across the public Internet infrastructure.

Internet can be defined as an electronic network of computers that includes almost every organization, university and government organization in the world while intranet is something like a private network inside a particular region, say an organization that uses the same kind of software which would also be found on internet!

technically all are same that is being connected to other computers.In internet you are connected to a large no. of computers through your internet service provider.In the case of intranet you may be connected to less number of PCs.even only 2 computers can be called an intranet.

Intranet A network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization. An intranet's Web sites look and act just like any other Web sites, but the firewall surrounding an intranet fends off unauthorized access. Like the Internet itself, intranets are used to share information. Secure intranets are now the fastest-growing segment of the Internet because they are much less expensive to build and manage than private networks based on proprietary protocols.

Internet The Internet, or simply the Net, is the publicly accessible worldwide system of interconnected computer networks that transmit data by packet switching using a standardized Internet Protocol (IP). It is made up of thousands of smaller commercial, academic, domestic, and government networks. It carries various information and services, such as electronic mail, online chat, and the interlinked Web pages and other documents of the World Wide Web. Contrary to some common usage, the Internet and the World Wide Web are not synonymous: the Internet is a collection of interconnected computer networks, linked by copper wires, fiber-optic cables, wireless connections etc.; the Web is a collection of interconnected documents, linked by hyperlinks and URLs, and is accessible using the Internet. http://en.wikipedia.org/wiki/internet... hope it helps you!!
