ARPAnet ARPAnet was the small network of individual computers connected by leased lines that marked the beginning of today's global data networks. Being an experimental network mainly serving the purpose to test the feasibility of In 1969 ARPANET went online and links the first two computers, one of them located at the University of California, Los Angeles, the other at the Stanford Research Institute. But ARPAnet has not become widely accepted before it was demonstrated in action to a public of computer experts at the First International Conference on Computers and Communication in Washington, D. C. in 1972. Before it was decommissioned in 1990, In the USA commercial users already outnumbered military and academic users in 1994. Despite the rapid growth of the Net, most computers linked to it are still located in the United States. |

National Science Foundation (NSF) Established in 1950, the National Science Foundation is an independent agency of the U.S. government dedicated to the funding in basic research and education in a wide range of sciences and in mathematics and engineering. Today, the NSF supplies about one quarter of total federal support of basic scientific research at academic institutions.

Satellites Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure. On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.

Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network. http://www.it.kth.se/docs/early_net/ |
