GENERATION OF COMPUTER

John Robert v. manalo

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.

First Generation The Vacuum tube

It was made in 1951 The first UNIVAC (universal automatic

computer)developed Mauchly and Eckert it was first used by US bureau of census.

UNIVAC 1

It was made in (1959-1964)Transistors enable computer designers to

build circuits in smaller spaces and run them on much less electricity.

Second Generation The Transistor

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

Third Generation The Integrated Circuit

It was made in 1971 A microprocessor is an integrated circuit

that contains thousands of transistors. Modern microprocessors contain more than 10 million transistors.

Fourth Generation The Microprocessor

Computers built with microprocessors are called microcomputers (or home computers or personal computers).

The Microcomputers

It was made in 1981 IBM entered the microcomputer business

and introduced the IBM PC which used the 4.77MHz intel 8088 microprocessor.

The IBM PC

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 Apple 11

The VSLI(very large-scale integrated)circuits brought about the

development of a special family of high-capability machines known as the super

computers.

The Supercomputers

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.

Cray 1

The fastest supercomputer in the world is IBM Blue/L

It 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 IBM Blue/L

The term fifth was coined by Japan to indicate the next generation of computers which had been planed to be created in the mid-90s

Researches had been made on the generation area of AI (artificial intelligence).
