"Stealth Sites" "Stealth sites" account for a particular form of hidden advertisement. Stealth sites look like magazines, nicely designed and featuring articles on different topics, but in reality are set up for the sole purpose of featuring a certain companies products and services. "About Wines" for example is a well-done online magazine, featuring articles on food and travel and also publishes articles on wine, which surprisingly all happen to be from Seagram.

4000 - 1000 B.C. 4th millennium B.C. In Sumer writing is invented. 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 hieroglyphs are used. 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.

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 "Enigma Machine". He also championed the theory that computers eventually could be constructed that would be capable of human thought, and he proposed the Turing test, to assess this capability. Turing's papers on the subject are widely acknowledged as the foundation of research in artificial intelligence. In 1952 Alan M. Turing committed suicide, probably because of the depressing medical treatment that he had been forced to undergo (in lieu of prison) to "cure" him of homosexuality.
