The Internet: where does it come from and who does it belong to?
With over 30 million users (the number can only be estimated) and a current growth that industrial companies can only dream of, the Internet is the most impressive "information superhighway" of our time. In order to understand the structure of the Internet, it is worth taking a closer look at its historical development: as the development of the U.S. Department of Defense's Advanced Research and Projects Agengy, this network was established in 1969 in the context of the Cold War (Arpanet). It was intended to reduce the vulnerability of American military facilities in the event of war by exchanging data using special computer protocols (TCP / IP, Transmission Control Protocol / Internet Protocol): The data was sent in small, special packages in a star shape so that the desired addressee could no longer be reached without any problems to reach others. Since, contrary to expectations, scientists were soon using this "secret" network to exchange information, the military component was cut off in the early 1980s. The civil rail of this network initially represented a connection for purely scientific purposes between US universities with mainframes, government agencies, NASA and the National Institute of Health, funded by the US National Science Foundation.
In the early 90s, the Internet opened up to commercial needs: today the proportion of commercial participants is around 90%. The breakthrough came with an easy-to-use graphical user interface, called WWW (World Wide Web): It was created in 1989 in the Swiss physics laboratories of CERN. The aim was to bring an "Esperanto" into the tangle of computer languages. The central axis of the WWW is the HTML (HyperText Mark-up Language), with which one moves in an almost three-dimensional way from document to document - from continent to continent - without noticing it. Today you can "surf" intuitively through the WWW with practically any computer and operating system. You can find everything on the Internet: from the collection of paintings in the Louvre to a wide range of espresso machines.
Recently, numerous primary schools have also connected to the Internet in order to familiarize children with the network at an early stage, which is done in a playful way on the web. You can log on to the Internet via numerous commercial or private providers (overview e.g. in PC-Online, 3/95 or Online-ISDN 6/95). The monthly basic fees are between DM 20 and DM 150. According to the history of its origins, the Internet - the "network of networks" - does not belong to anyone. There is no central registration point and no central monitoring. The Internet thus reflects anarchy - in the philosophical sense of the word: a utopian society of individuals without state regulation.
