Age of computers,
computer generation 1 (1937-1953) in the computer uses vacuum tubes and relays are devices in the circuit instead of mechanical. In principle, the operation of the electric Leibowitz. (Open - closed circuit) is more reliable than that. And use of electricity are faster than using a mechanical switch to 1000-fold, however, that this vacuum tubes. The disadvantage is the need of energy. Short lifetime It is important that large. This is the imperfection of the computer era. For example, the ENIAC computer have to use the tube vacuum to 18,000 tubes, the power to 140 kW and weighing up to 30 tons, computers, electronics, home of the world's computers, ABC (1937) developed by Dr. John v. North. The Nassau Jeff (John V Atanasoff) and Cliff Ford, Burberry (Clifford Berry) This machine can not program. It is the basis for the electronic computer binary generations later, in 1943, have a computer, electronics, machine Colossians 2 is Zeus. This machine was built to take advantage of the military, that is. Used to decode the German army used to communicate. In World War 2, but computer Colo Zeus is kept confidential. Until the late 1970s, which ended World War 2, it was revealed later in the year 1943 J. Presper Eckert and John V. Mauchly have collaborated to create the first large-scale electronic computer. As computers for general use, and build successfully in 1945 and is named Enigma action (ENIAC: Electronic Numerical Integrator and Computer) This machine weighs 30 tons, consisting of vacuum tubes, 18,000 tubes space of 30x50 to move the power to. 160 kW at an Enigma machine is turned on first. Light bulb with a dimmer to dim the city Philadelphia, which this machine was built here ENIAC was built to serve in the military as well. They are used to calculate the square, shooting ranges, and later the two of you have created the UNIVAC (UNIVAC: Universal Automatic Computer) was launched. The first computer that was designed to be used in the trade as a UNIVAC in the market, people began to realize the importance of computers. After seeing the results of the analysis work correctly pronounce five percent of the people. Of the total population Correctly that Mr. Dwight D. Eisenhower would win the presidential election in the United States. In an election year. Since 1953.
