History and Evolution of Computer

History and Evolution of Computer Around 300 BC. It is believed to be earlier, when humans used wood, stones, fingers and bones for counting.

In fact, human invented Computer in search of a Calculating Device . In today’s post, we are going to tell you about the history and development of computers. Let’s see History and Evolution of Computer

History and Evolution of Computer

If you want to know about the history of the computer, then you have to first know how humans used to calculate large numbers.

Many systems of numeration are used in this process of accounting such as a Babylonian system of numeration, the Greek system of numeration, the Roman system of numeration and the Indian system of numeration.

Now let’s discuss some such computing devices which have a big contribution in this direction.

Calculating Machines

Creating mechanical devices so that large numbers can be counted.


The first calculating device is ABACUS. It was developed by Egyptian and Chinese people. ABACUS means calculating board . It consists of sticks in horizontal positions. In which small small size pebbles are inserted.

There are many horizontal bars in which each one has ten beads. Horizontal bars represent units, tens, hundreds, etc.

Napier’s Bones

It was developed by English mathematician John Napier in the year 1617 AD . It is such a mechanical device. It was created for the purpose of multiplication.

Slide Rule

English mathematician Edmund Gunter developed the slide rule. This machine can perform many operations very easily such as addition, subtraction, multiplication , and division .



This machine was invented by the then famous French Scientist and Mathematician, Blaise Pascal, who was only 19 years old at that time. This machine could easily add digits.


Gottfried further improved Pascal’s machine and devised a mechanism that was capable of automatic multiplication of numbers.


In the early eighteenth century, Joseph Marie Jacquard, a French weaver, developed a programmable loom, used large cards and holes of judges, then punch them with great control so that in the end A pattern was automatically created.


In the early period of the early 19th century, & nbsp; Charles Babbage , an Englishman, scientist, worked behind the development of a machine that easily performed complex calculations. Could do.

In 1813 A.D., he invention of this ‘Difference Engine ‘ which could perform very complex calculations and print it simultaneously. This machine was a steam-powered machine.

computer history in hindi – 19th century

You know about the history of computer of this modern time, which was developed during the 19th century.

Jacquard Loom

  • It uses metal cards .
  • Its first stored program was in metal cards
  • It was the first computer manufacturing unit was
  • It is used a lot of space

Difference Engine c.1822

  • It was a very big calculator
  • Charles Babbage (1792–1871) had a big hand behind it.

Analytical Engine 1833

  • This machine was able to store numbers.
  • It used punched metal cards for its calculating process.
  • It is a steam- powered machine was.

Ada Augusta – was the first programmer in the world

  • He worked with Charles Babbage
  • He also programmed Analytical Engine

Vacuum Tubes – (1930 – 1950s)

  • First Vacation Electronic Computers used Vacuum Tubes
  • Vacuum tubes are actually glass tubes with circuits i within them.
  • There is no air inside the vacuum tubes, which protects its circuitry.

UNIVAC – 1951

  • It was the first commercially available computer
  • It was sold to censu bureau
  • “There was a huge pocket calculator”

First Transistor

  • It used Silicon
  • It was developed in 1948
  • for which its inventor also got the Nobel prize
  • It has an on-off switch

Integrated Circuits

  • These Integrated Circuits (chips) were used in Third Generation Computers .
