A brief history of the Internet

In 1973 the Defense Advanced Research Projects Agency (DARPA) initiated a research program to investigate techniques and 1.____________ of various kinds. The objective was to develop communication protocols which would allow networked computers to communicate transparently across multiple, linked packet networks. This was called the Internetting project and the system of networks which 2.__________ was known as the “Internet” (Intercontinental Network).

During the course of its evolution, particularly after 1989, the Internet system began to integrate support for other protocol suites into its basic networking fabric. By the end of 1991 the Internet has grown to include some 5,000 networks in over three dozen countries, serving 3.____________used by over 4,000,000 people.

The bulk of the system today is made up of private networking facilities

in education and research institutions, business, and in government organizations

across the globe.

A secretariat has been created to manage the day-to-day function of the Internet Activities Board (IAB) and Internet Engineering Task Force (IETF). IETF meets three times a year in plenary and in approximately 50 working groups convene at intermediate times by electronic mail, teleconferencing, 4.____________.

There are a number of Network Information Centers (NICs) located throughout the Internet to serve its users with documentation, guidance, advice, and assistance. As 5._______________, the need for high quality NIC functions increases. Although the initial community of users of the Internet were drawn from the ranks of computer science and engineering, its users now comprise a wide range of disciplines in the sciences, arts, letters, business, military, and government administration
