History of the Internet
The history of the Internet can roughly be divided up into three phases. The bases which technology demonstrates and develops into the application ability were put in the early phase as of the middle of the 1960s years. With the change of the military to the academic support for research the growth and the international spreading of the Internet started contemporaneous with end of the seventies. What is associated generally with the wild phase of the original Internet prospered at this time: round every shutdown, everybody does restriction of the access and the liberal flow of information know an exchange economy for software and information, a grass root based self organization, Communitys developing and the hacker mind, this one to go how?
The Internet is medium historically an Anomalie. Like the technique genesis usual models generally run the media from the laboratory through the development to the application maturity up to the social implementation as a state either armed forces or administration communication, when economic Kontroll and control instrument or as a mass market product of the individual communication or the mass media. In the case of academic data networks differently however. There wasn't any separation between inventors, developers and users within the first years.
Computer science has not only its object of research but at the same time her communication and publication medium in the net. It is simultaneous for infrastructure which is improved from inside out and development environment. Innovations are tested and developed further by the colleagues from the developer users in the beta version, this means without guarantee and on own risk into the round thrown. Furthermore it provides the other, computerized increasingly infrastructure, this one is like sciences. Of meeting papers and databases on the Internet all this is the access to computing resources, the exchange within a worldwide Community of subject colleagues, part of the daily practices in the physics and astronomy, the computer science of themselves and increasing also in "softer" sciences, this to the discussion places of Preprints, the publication, for the eighties. Passing the basic tools on to these studying is finally part of the scientific teaching. Since the net doesn't have any narrowly defined application field but is just medium different from most laboratory equipment and leisure cultures on an explosive mixture of high tech and Hobbyismus, Science and science fiction, hackers and hippies, also pushes here student, private.
With the support for research for the implementation of TCP the DArpa had fulfilled its initial mission. The responsibility for the Arpanet was transferred to the Defense Communications Agency in 1975. The contractor stayed for the operation of the net with BBN but military security interests were getting more important now. In addition to the DArpa the National Science Foundation also promoted the research in computer science and networks to about 120 U.S. universities. Further facilities, how the energy department and NASA did networks of one's own start?
This disposed Arpanet over 61 nodes at the beginning of 1975. The first mailing list was set up. Together with the RFCs mailing lists become the most important means of the open cooperation of the technical Community. One discussed, however, science fiction in the most popular list of this time. The jargon file, a dictionary of the hacker culture arranged by Raphael Finkel, was published of course in the net for the first time.
Uucp was developed to AT&T Bell Labs and spread as a part of the UNIX version 7 in 1976. Uucp made it possible to exchange data about voter connections on normal telephone lines with computers at the Arpanet for facilities which couldn't afford any leased line.
The new network connecting TCP was demonstrated for the first time in an effortful test structure in July 1977. The transmission link started with a mobile package transmitter in an itinerant car on the San Francisco Bayshore Freeway, point to point satellite link ran to Norway to a Gateway at BBN about the Arpanet about one from there via country line to London, about the Atlantic packs back Satellite Network into the Arpanet and finally to the computer science institute the University of Southern California.
So what we feigned, somebody then was about an intercontinental satellite net on a mobile theater of war which moves about a continental net and then goes back into an electricity grid and to the main computer center of the national headquarters. Since the Ministry of Defense paid for it, we have searched for examples which could be interesting for a military scenario.
Since the middle of the seventies experiments were executed to the packet-switched voice transmission. TCP is designed for a reliable transmitting. Packages which are lost are sent once more. The loss of some packages is, however, less adverse in the case of voice transmission than a delay. Out of these considerations 1978 TCP and IP got separated. This specifies users data grief Protocol which is still used for the voice transmission today IP. The Arpanet experiment is finished officially with that in 1978. It is called in the final report.
This Arpa program has produced nothing in the computer technology less than a revolution and was one of the most successful projects which has ever executed the Arpa. The full extent of the technical change which starts out from this project can be estimated perhaps only within many years.
