Computer models One
computer in the first version was launched in 2494 by the science of the vacuum tube (vacuum tube) and electronic circuit create logic circuit (logic circuit) of the computer. For memory Use science of drum magnet (magnetic drum) in the first period was later used science of magnetic core (magnetic core) in record-keeping and early outcome and input commands will be full of computers. (punched card), but in the latter. He started using the magnetic stripe (magnetic tape) to enter and record-keeping. The computer model is equipped with vacuum tubes. Which is larger and Require large amounts of electricity The first version of this computer is so large. Use more space And a heat source The lifetime of the vacuum tube is relatively short. And maintenance of computers. It will be replaced vacuum tubes frequently. Examples of the first computer that success in this first edition is waxing machine unit 1 (UNIVAC I - Universal Automatic Computer), which affects up in 2494 and sold about 46 machines.
