First Generation

1. First genesis (1944-1959) Vacuum tube as a indication amplifier, it was a typical scratch line-generation calculator. Initially, void tubes (vacuum-tube) are apply as a component of the signal amplifier. bare-ass materials consist of glass, so much has disadvantages, such as easily broken, and easy to distri furthere the heat. This heat postulate to be neutralized by other components that exercise as a coolant. And with the additional component, the computer ultimately appeared to be a big, heavy and expensive. In 1946, the worlds first electronic computer the ENIAC sesai made. On the computer contained 18,800 vacuum tubes and weighs 30 tons.So large in size, to the point that requires a separate classroom. In the seems image ENIAC computer, this is the worlds first electronic computer that has a weightiness weighing 30 tons, duration 30 M and 2. 4 M in high spirits and requires 174 kilowatts of electrical power. * fiend was the first electronic computer of this era. Its each aspect was kept secret by British Government. * This is the worlds first electronic computer that has a weight weighing 30 tons, length 30 M and 2. 4 M high and requires 174 kilowatts of electrical power. * In 1945, Von Neumann Architecture was introduced.Eckert and Mauchley began working(a) on EDVAC (Electronic Discrete Variable Automatic Computer) but it never completed. Later Von Neumann developed his profess EDVAC (IAS machine). * In 1946, the development of ENIAC (Electronic Numerical Integrator and Computer), which was started in 1943, was completed. * Some other computers of this generation are UNIVAC, remember II, MARK III, Z2, Z4, SSEC (Selective Sequence Electronic calculator) and some IBM computers serial such as IBM 604, IBM 650, IBM 701, IBM 702. * In 1954, first recitation of FORTRAN (Formula Translator) was published by IBM
