Produktbeschreibung

What is commonly called the information age began with a double big bang. It was 1948 and the United States of America was continuing to invest heavily in high-tech research, the ?rst advantages of which had been reaped during the Second World War. In the Bell Telephone Laboratories, set up in New Jersey, to the south of New York, several teams were set up around brilliant researchers, manyofwhomhadbeentrainedatMIT(MassachusettsInstituteofTechnology). Thatyeartwoexceptionaldiscoveriesweremade,onetechnologicalandtheother theoretical, which were to mark the 20th century. For, a few months apart, and in the same institution John Bardeen, Walter Brattain and William Shockley invented the transistor while Claude Elwood Shannon established information and digital communications theory. This phenomenal coincidence saw the birth ofnear-twins: thesemi-conductorcomponentwhich, accordingtoits conduction state (on or o?), is able to materially represent binary information ("0" or "1") andtheShannon orbit (shortforbinaryunit), a unit that measuresinformation capacity. Today we can recognize the full importance of these two inventions that - abledthe tremendousexpansionofcomputing andtelecommunications,to name but these two. Since 1948, the meteoric progress of electronics, then of mic- electronics, has providedengineers and researchersin the world of telecommu- cations with a support for their innovations, in order to continually increase the performanceof their systems.
