Computer Communications

Most of the world's major computers are linked together into gigantic electronic networks. The internet, the largest computer network in the world, links over 350,000 computer installations, most with thousands of users, in 26 countries. Because of its strategic importance, in the U.S. the internet is supported by the Defense Advanced Research Projects Agency, the National Science Foundation, the National Aeronautics and Space Administration, and the Department of Energy. This subsection discusses the technology used to connect computers.
