4000 - 1000 B.C. 4th millennium B.C. In Sumer Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets were used for administrative purposes. As an instrument for the administrative bodies of early empires, which began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to only very few. Being more or less separated tasks, writing and calculating converge in today's computers. Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China. 3200 B.C. In Sumer the seal is invented. About 3000 B.C. In Egypt papyrus scrolls and About 1350 B.C. In Assyria the cuneiform script is invented. 1200 B.C. According to Aeschylus, the conquest of the town of Troy was transmitted via torch signals. About 1100 B.C. Egyptians use homing pigeons to deliver military information. |

Virtual cartels, introduction Among the most striking development of the 1990s has been the emergence of a global commercial media market utilizing new technologies and the global trend toward deregulation. This global commercial media market is a result of aggressive maneuvering by the dominant firms, new technologies that make global systems cost-efficient, and neoliberal economic policies encouraged by the World Bank, IMF, WTO, and the US government to break down regulatory barriers to a global commercial media and telecommunication market. A global oligopolistic market that covers the spectrum of media is now crystallizing the very high barriers to entry." (Robert McChesney, author of "Rich Media, Poor Democracy") The network structure of information and communication technologies means that even deregulated markets are not "free". The functional logic of global networks only tolerates a small number of large players. Mergers, strategic alliances, partnerships and cooperations are therefore the daily routine of the ICT business. They bypass competition and create "virtual cartels". |

Central processing unit A CPU is the principal part of any digital computer system, generally composed of the main memory, control unit, and arithmetic-logic unit. It constitutes the physical heart of the entire computer system; to it is linked various peripheral equipment, including input/output devices and auxiliary storage units... |

Alan Turing b. June 23, 1912, London, England d. June 7, 1954, Wilmslow, Cheshire English mathematician and logician who pioneered in the field of computer theory and who contributed important logical analyses of computer processes. Many mathematicians in the first decades of the 20th century had attempted to eliminate all possible error from mathematics by establishing a formal, or purely algorithmic, procedure for establishing truth. The mathematician Kurt Gödel threw up an obstacle to this effort with his incompleteness theorem. Turing was motivated by Gödel's work to seek an algorithmic method of determining whether any given propositions were undecidable, with the ultimate goal of eliminating them from mathematics. Instead, he proved in his seminal paper "On Computable Numbers, with an Application to the Entscheidungsproblem [Decision Problem]" (1936) that there cannot exist any such universal method of determination and, hence, that mathematics will always contain undecidable propositions. During World War II he served with the Government Code and Cypher School, at Bletchley, Buckinghamshire, where he played a significant role in breaking the codes of the German " |

John von Neumann b. December 3, 1903, Budapest, Hungary d. February 8, 1957, Washington, D.C., U.S. Mathematician who made important contributions in quantum physics, logic, meteorology, and computer science. His theory of games had a significant influence upon economics. In computer theory, von Neumann did much of the pioneering work in logical design, in the problem of obtaining reliable answers from a machine with unreliable components, the function of "memory," machine imitation of "randomness," and the problem of constructing automata that can reproduce their own kind. |
