The story of the computer - Full Tutorial

The calculation always made man a problem. Hence, man tried to use a convenient method, and as a result, he found a manual operating mechanism. This was called "Abacus". It was produced by the Chinese about 2000 years ago.


This is a thin-striped wooden frame. The miniature balls are mounted on the scenes. And the lines were crossed. There is another slim collar. There are two pieces of small round balls on top of the top, each bar topping each with seven round rounds. These small balls can be moved according to the rules. They should refer to problems that need to be solved. An Abacus operator can add more speeds to the current calculator.

Russian and Japanese abacus more than Chinese Abacus. But those machines can be performed equally in the same way, and only the rules in which they work can be seen. This horizontal-mounted device is one of the Number one enhancement options. Each of these wooden pieces has numbered 1-9 and added the value of each number by adding each number.


In 1642, the calculator discovered by French lawyer Blace Pascal named it. This is called the earliest calculator in the world. Each wheel is made up of 0 to 9 disks in each wheel of the machine, connected to a pinch and wheel. Rotating the rotors accordingly enables the number to be added to the machine.

Charles Babbage

He is a English national. He designed a "Difference Engine" machine. In 1822, its main goal was to compute multiplications and tables. At that time, however, technology had not been so advanced and technically costly planned and abandoned. After that, From 1833 to 1834, he was planning another machine, which was a machine that was steam powered. He called the "Analytical Engine".

A large number of features on the modern Computer included him. Unfortunately, this machine could never be manufactured. But Charles Babbage has been able to name the name of the computer in the very top, and today he remembers him as "the father of the computer".

Ada Augusta

Also, "Ada Augusta" developed the idea of computer programs, as a friend and assistant of Charles Babbage's computer software, and as "the first computer programmer" (computer programmer ) Today is also commemorated.

Tabulating Machine

The creation of the TAB is owed by a US citizen. In 1880, Hermann Hollerith. It took about 8 years to produce these kinds of manuscripts. Herman sought to find this machine to help prevent this amount. This made it possible to do a quick calculation.

The world's first computer

His dream planned by Charles Babbage came true after 70 years of his death. Howard Aiken of the Harvard College, Hawaii, Hawaii, USA, in 1930, I.B.M. This machine was developed with a company engineer and started to manufacture this machine. This was a full automatic. This machine was capable of adding and lowering the numbers in a second. It also takes seconds for this count to count. This was the first computer to be called the Automatic Sequence Controlled Computer (ASCC).

Electronic computer

After the ASCC was discovered, its upgrading continued. During World War II, during the Second World War, a tactile gun for the Allied Forces was a prerequisite for shooting targets and was required to find the Electronic Numerical Integrator and Computer (or ENIAC) to fulfill this essential requirement.

This ENIAC computer had a faster speed than the earlier machines. It has the ability to decrypt and add 5000 reductions, 350 upgrades, or 50 split resolutions in a second. But this computer was very large.

John Von

Improvements continued. John Von Neumann has joined in developing the ENIAC. He said that the computer can not only store data and counted results.

He believed that a program could be included to do the instructions in accordance with the instructions given earlier. Six years later, in 1949, the first electronic computer was produced by the University of Cambridge at the University of Cambridge. This was the Electronic Delay Storage Automatic Calculator (EDSAC).

These developments led to the emergence of a modern computer.
