History and Development of Computer

Abacus

The history of computers is about 3000 years old. When the calculation machine Abacus was invented in China, it is a mechanical device that was still used to calculate numbers in many countries of Asia including China and Japan. Abacus is a frame of wires. Beads (baked clay balls) are threaded in these wires. Initially, Abacus was used by traders for calculation work. This machine is used to add, subtract, multiply and divide numbers. come

 

Blase Pascal

Over the centuries, many other mechanical machines were developed to calculate numbers. In the 17th century, French mathematician Blaise Pascal developed a mechanical digital calculator in 1645. This machine was called adding machine because it could only add or subtract. This machine worked on the principle of a clock and odometer. There were many toothed wheels in it, which used to rotate. Numbers from 0 to 9 were printed on the teeth of the wheels. Each wheel had a place value like units, tens, hundreds, etc. After this, the second cycle used to rotate. This adding machine of Blase Pascal is also called Pascaline.

 

Jacquard’s Loom

In 1801, the French weaver Joseph Jacquard invented such a loom for weaving cloth, which controlled the design or pattern in the cloth with punched punch cards of cardboard. The specialty of this loom was that it controlled the pattern of the cloth with a cardboard punch card with holes, the threads were guided by the presence or absence of pictures on the punch card.

 

 

 

Charles Babbage

In the history of computers, the 19th century is considered to be the golden age of the initial period. English Mathematician Charles Babbage felt the need to develop a Mechanical Calculation Machine when there was an error in the tables made for calculation.

Charles Babbage built a machine in 1822, the cost of which was borne by the British government. That machine was named Difference Engine, this machine had gears and shafts. It used to run on steam. In 1833, Charles Babbage developed the Analytical Engine, a developed form of a Different Engine, which was a very powerful machine. Babbage has made a huge contribution to the development of computers. Babbage's Analytical Engine became the basis of the modern computer and this is the reason why Charles Babbage is called the father of computer science.

 

Dr. Howard Aiken’s Mark-I

Electrometrical Computing reached its peak in the 1940s. Four top IBM engineers and Dr. Howard Aiken developed a machine in 1944. It was the world's first "electromechanical computer" and was officially named Automatic Sequence Controlled CalculatorIt was sent to Harvard University in February 1944 and was received at the university on 7 August 1944. It was named Mark-I in this university. It could do 1 multiplication in 6 seconds and 1 division in 12 seconds.

 

A.B.C. (Atanasoff – Berry Computer)

In 1945, Atanasoff and Clifford Berry developed an electronic machine named ABC. The word ABC is short for Atanasoff Berry Computer. ABC was the first electronic digital computer.
