It was made in (1951-1959)The vacuum tube is an electronic tube (about size of a light bulb) from which essentially all air has been removed, creating a vacuum. It was also used to build radios.
It was made in 1951The first UNIVAC (universal automatic computer)developed Mauchly and Eckert it was first used by US bureau of census.
It was made in (1959-1964)Transistors enable computer designers to build circuits in smaller spaces and run them on much less electricity.
It was made in (1964-1970)The IC(integrated circuit)is a complete electronic circuit which was made by Kilby and Robert. it is made of square silicon sides 5mm (1/8inch) in diameter
It was made in 1971A microprocessor is an integrated circuit that contains thousands of transistors. Modern microprocessors contain more than 10 million transistors.
Computers built with microprocessors are called microcomputers (or home computers or personal computers).
It was made in 1981IBM entered the microcomputer business and introduced the IBM PC which used the 4.77MHz intel 8088 microprocessor.
It was made in 1977Two young computer enthusiasts, Steven Paul Jobs and Stephen Wozniak (then 21 and 26 years of age) built apple11 in 1976 the first computer circuit board.
The VSLI(very large-scale integrated)circuitsbrought about the development of a special family of high-capability machines known as the super computers.
It was made in 1976The Cray 1 was the super computer design by Seymour Cray of Cray research in Eagan, Michigan. It was the first computer capable performing over 100million calculation per seconds.
The fastest supercomputer in the world is IBM Blue/LIt is a revolutionary, low cost machine delivering extraordinary computing power located in the terascale simulation facility of Lawrence Livermore national laboratory, California for scientific simulation and for evaluating advanced computer architectures.
The term fifth was coined by Japan to indicate the next generation of computers which had been planed to be created in the mid-90sResearches had been made on the generation area of AI (artificial intelligence).
