Evolution of computer

good morning and jai jagat to all 🙂

Evolution of computer

• The step by step development in computers is known as evolution of computers.

• there are five generation of computers.

1st generation

In accordance with the methodology for assessing the development of computer technology, the first generation was considered to be vacuum tube computers.

Example EDVAC,UNIVAC

2nd generation

A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. ... A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory.

Example IBM 1620, IBM 7094

3rd generation

The period of third generation was from 1965-1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry. ... This development made computers smaller in size, reliable, and efficient.

Example IBM-360 series, Honeywell-6000 series

4th generation

The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. Fourth generation computers became more powerful, compact, reliable, and affordable.

Example IBM 4341, DEC 10

5th generation

The Fifth Generation Computer Systems (FGCS) was an initiative by Japan's Ministry of International Trade and Industry (MITI), begun in 1982, to create computers using massively parallel computing and logic programming. It was to be the result of a government/industry research project in Japan during the 1980s.

fact

In 1833 a man by the name of Charles Babbage invented all the parts that are now used for a modern computer. But it was only 120 years later that the first 'modern' computers were invented. Konrad Zuse was the inventor of the first computer in the world in 1936 and he named it the Z1.
