First Generation

1. First Generation (1944-1959) Vacuum tube as a signal amplifier, it was a typical first-generation computer. Initially, vacuum tubes (vacuum-tube) are used as a component of the signal amplifier. Raw materials consist of glass, so oftentimes has disadvantages, such as easily broken, and easy to distribute the heat. This heat demand to be neutralized by other components that serve as a coolant. And with the additional component, the computer finally appeared to be a big, heavy and expensive. In 1946, the instaurations 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 prototype ENIAC computer, this is the worlds first electronic computer that has a heaviness deliberateness 30 tons, length 30 M and 2. 4 M eminent and requires 174 kilowatts of electrical power. * Colossus was the first electronic computer of this era. Its every 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 on EDVAC (electronic trenchant Variable Automatic Computer) but it never completed. Later Von Neumann highly-developed his own EDVAC (IAS machine). * In 1946, the development of ENIAC (Electronic Numerical Integrator and Computer), which was started in 1943, was completed. * round other computers of this generation are UNIVAC, MARK II, MARK III, Z2, Z4, SSEC (Selective Sequence Electronic calculator) and some IBM computers series such as IBM 604, IBM 650, IBM 701, IBM 702. * In 1954, first reading material of FORTRAN (Formula Translator) was published by IBM
