Acessing the Internet The Net connections can be based on wire-line and wireless access technolgies.
Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables Satellite communication Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks. Privatization of satellite communication Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Scheduled privatization of intergovernmental satellite consortia:
When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers. As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost. Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

1000 B.C. - 0 900 B.C. A postal service is used for governmental purposes in China. 500 B.C. In ancient Greece trumpets, drums, shouting, beacon, fires, smoke signals, and mirrors are used for message transmission. 4th century B.C. Aeneas Tacitus, a Greek military scientist and cryptographer, invented an optical communication system that combines water and beacon telegraphy. Torches indicated the beginnings and the ends of a message transmission while water jars were used to transmit the messages. These jars had a plugged standard-size hole drilled on the bottom side and were filled with water. As those who sent and those who received the message unplugged the jars simultaneously, the water drained out. Because the transmitted messages corresponded to water levels, the sender indicated by a torch signal that the appropriate water level had been reached. The methods disadvantage was that the possible messages were restricted to a given code, but as the system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand the messages unless they possessed the codebook. With communication separated from transportation, the distant became near. Tacitus' telegraph system was very fast and not excelled until For further information see Joanne Chang & Anna Soellner, Decoding Device, 3rd century B.C. Wax tablets are used as writing material in Mesopotamia, ancient Greece, and Etruria. 2nd century B.C. In China paper is invented. 1st century B.C. The use of codices instead of scrolls - basically the hardcover book as we know it today - is an essential event in European history. To quote accurately by page number, to browse through pages and to skip chapters - things that were impossible when reading scrolls - becomes possible. In the computer age we are witnesses to a kind of revival of the scrolls as we scroll up and down a document. The introduction of hypertext possibly marks the beginning of a similar change as has taken place with the substitution of scrolls with codices. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Databody economy and the surveillance state
The glamour of the data body economy clouds economic practices which are much less than glamorous. Through the seizure of the data body, practices that in the real political arena were common in the feudal age and in the early industrial age are being reconstructed. The data body economy digitally reconstructs exploitative practices such as slavery and wage labour. However, culturally the data body is still a very new phenomenon: mostly, people think if it does not hurt, it cannot be my body. Exploitation of data bodies is painless and fast. Nevertheless, this can be expected to change once the awareness of the political nature of the data body becomes more widespread. As more and more people routinely move in digitised environments, it is to be expected that more critical questions will be asked and claims to autonomy, at present restricted to some artistic and civil society groups trying to get heard amidst the deafening noise of the commercial ICT propaganda, will be articulated on a more general level. The more problematic aspect of this development may be something else: the practices of the data body economy, themselves a reconstruction of old techniques of seizure, have begun to re-colonise real political space. Simon Davis, Director of the London-based privacy campaigners The constant adaptation process required from the modern individual has anonymised and structuralized punishment, which now appears in the guise of error messages and the privatisation of risk. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Noam Chomsky Noam Chomsky (* 1928) works as a U.S.-linguist, writer, political activist and journalist. He is teaching at the MIT (= Massachusetts Institute of Technology) as a professor of linguistics, specializing on structural grammar and the change of language through technology and economy - and the social results of that. When he stood up against the Vietnam War he became famous as a "radical leftist". Since then he has been one of the most famous critics of his country. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
