Introduction to Internet Protocol model

INTERNET

Internet was a stock it would be considered a market phenomenon, with sustained doubling growth and no apparent end in sight to the upward spiral. Recent Internet numbers are stunning. Between January 1993 and January 1994 alone, the number of nodes grew from 1,313,00 to 2,217,000, an impressive 69% increase. Over 70 countries have full Internet connectivity and about 150 have at least E-mail services. No discussion of telecommunications would be complete without discussing the Internet, referred to by its millions of users as the Net. The Net evolved from ARPANET, a research network created and subsidized in the 1960s by the Defense Department and the National Science Foundation (NSF) to link research institutions and government agencies around the world to exchange information on a wide range of topics. Although the original ARPANET no longer exists, its design and architecture laid the foundations for the Internet.

The Net, one of the oldest long distance networks in the country, is a network of networks. It links approximately 1.5 million computers, attached to more than 13,000 networks, in 100 or more countries. The Internet is an effective form of use of media for dissemination of geographic information systems of high-level and related mapping services.

Businesses use the Net for a number of tasks, such as sharing files, sending E-mail, and selling goods and services. Less than 1% of major companies today are not attached to the Internet. In fact, the Internet has become such an integral part of the corporate landscape that it is generating a number of entrepreneurial opportunities and highly specialized jobs: there are Internet explorers, security experts, technicians, librarians, trainers, and other service providers. In fact, the Internet is becoming so common that many employers expect their new hires to have a working knowledge of it.

Think of the Internet as a huge repository of information on almost every topic imaginable. People all over the world can search the net for information; add new information, and exchange views on different topics. The Internet is an electronic web that connects people and businesses that have access to networks and allows them to send and receive E-mail and to participate in a number of other activities, around the clock. In fact, the Internet is so huge, with such a wide variety of features, that there are few, if any, experts in the world who know everything about it.

Thus in spite of its enormous power and potential, no one really owns the Internet, although some segments of it may have their own funding and guidelines. The primary workings of the Internet are funded by the National Science Foundation (NSF); the Internet Engineering Task Force (IETF), a committee of scientists and experts, provides technical supervision, standards, and guidelines for the Net.
