HISTORY OF COMPUTER – HISTORY OF COMPUTER

Today everyone is using computer in the world. And it is also the biggest invention of the digital world. So its history will also be interesting,  in this post it has been told about the development of computer from the first generation till now.

History Of Computer – History Of Computer 

The word computer is derived from the Latin word computer, which means to calculate. Computer was invented only for computing but today it has become very elaborate and it is used extensively.

After the Second World War, the development of computers was very rapid and there were many changes in their shape and size. The history of the development of modern computers is divided into several parts according to the technological development.

first generation computers 

Talking about the first generation computer, it was made for general calculation, whose features are as follows-

  1. The era of this generation of computers is considered to be from 1946 to 1955.
  2. In this generation, vacuum tubes were used in computers.
  3. The size of computers of this generation was so large that it filled a room.
  4. The first generation computers were so hot that they needed an air conditioner to cool them down.
  5. The speed of these computers was not as high as the computers of today, due to which it could not run much and its prices were also very high according to its speed.

first generation computer name

  1. eneac
  2. edsac 
  3. UNIVAC-1
  4. UNIVAC-2
  5. IBM-701 

second generation computers 

The development of this generation of computers is considered to be from 1956 to 1965. The second feature of this generation of computers is that transistors were now being used in these computers instead of vacuum tubes. 

Second generation computers were smaller in size, faster in speed, more reliable and also cost less. It was very easy to store and retrieve data in this generation of computers. 

Computers of this generation are the IBM-1401, which was very popular and was produced on a very large scale.

computers of this generation 

  1. IBM-1602
  2. IBM-7094
  3. CDS-3600
  4. RCA–501

third generation computers 

The time of third generation computers is considered to be from 1966 to 1975.

Chips were used in these , which were very small in size. Hundreds of transistors could be integrated on a single chip. 

The size of computers made in this generation used to be very small and reliable and speed was also very fast. 

With the development of this generation of computers, various types of data storage peripherals were developed. For example, discs, tapes etc. also developed. 

The development of computer  made it  possible to do multi programming  and   multiprocessing . Computers of this generation used to be small in size as well as cheap.

The names of the main computers of this generation were as follows-

  • 1. IBM-360
  • 2. IBM-370
  • 3. ICL-1900
  • 5. Burroughs 5700
  • 7. CDC-3000
  • 9. UNIVAC 9000

fourth generation computers

The time of this generation of computers is considered to be from 1976 to 1990. In these, all the integrated circuits of the computer are installed on only one silicon chip.

Which is called microprocessor. Computers using these chips in this way are called microcomputers. Another feature of this type of computer is that it consumes less electricity and it is able to work even at normal temperature.

In this generation of computers, the category of personal computers came into existence, which is   called Pentium . Computers of this generation are mainly of Pentium class. From Pentium-1 to Pentium-4. 

fifth generation computers 

Since 1990, the time till now is the fifth generation of computers, in which efforts are being made to manufacture such computers.

In which along with the high capabilities of computers, there is also the ability to reason, make decisions and think. 

The main focus of this generation of computers is on knowledge processing rather than data processing.

About this fifth generation of computers, scientists claim that these computers will be very similar to the human brain.

So far, success has not been achieved in making such computers, but such computers have been made which have much more capabilities than the computers made in the fourth generation. 

These are called supercomputers, which alone can do the same work as hundreds of computers.

type of computer

There are mainly three types of computers –

1. Analog computers – These exploit mathematical similarities between physical interactions in certain problems and use electronic or hydraulic circuits to solve physical problems.

2. Digital Computer – This type of computer performs calculations and solves problems on the basis of each number digit by digit.

3. Hybrid Computer  – Hybrid computer is called those computers, in which the properties of both analog and digital computers are found.

By converting physical quantities into numbers, they are taken into digital form. It is most widely used in the field of medicine.

Now I am going to present you the history of computer in brief which is as follows.

16th century , Inventor – Li Kai Chen , Inventor – Abacus , Attribute – To aid in calculation tasks. 

1617 , Inventor – John Napier , Invention – Napier Bones, Characteristic – To multiply quickly. 

1642 , Inventor – Blaise Pascal , Invention – Counting machine , Specialty – First counting machine. 

1671 , Inventor – Gottfried von Leibniz, Invention – Mechanical calculator , Specialty – Addition and subtraction as well as multiplication and division. 

1823-34 , Inventor – Charles Babbage , Invention – Difference Engine, Characteristic – Values ​​of algebraic functions could be found accurately to 20 places of decimal.

1880 , Inventor – Hermann Hollerith , Invention – Census tabular, operated by electrically operated pentagons. 

1937 – 38 , Inventors – Johnvy Atanasoff and Clifford Berry , Invention – ABC , Specialty – Completely electronic, it did not have a single mechanical part.

Friends, in today’s page, that’s all, you will meet again with some other information, thank you very much.
