A French man named Blaise Popkal created mechanical calculations in 1642. This device was named Pascalen. Later, in his honor, a modern programming language named Computer has been named Pascal.

Abacus is considered as the first device in computer history. That is, the history of computer started with abacus. Abacus was a series of capsules that were arranged in a frame and counting instruments. Although the abacus is invented, it can not be said correctly.

Many think that it is made of the Babylonian civilization. In 450/500 BC, the abacus machine was considered to be a counting machine in Egypt and China. At present, in the era of electronic development of electronic technology, in particular countries in China, Japan, Russia, etc., the abacus device is still used. As a sign of tradition, they continue to carry thousands of years of age abacus devices.

Even though it is able to meet the needs of the society, the need of a more advanced machine is required for counting work in the medieval period. On the basis of the needs and needs of life, it changes so much that the need for automatic equipment is required. In view of the goal of facilitating calculation, Scottish mathematician John Napier discovered the algorithm system in 1614. This method is also called Napier bone.

Using this method, German scientist William Oureate invented the round slide rule. That was the year 1922. The following year, another German scholar named Schmidt discovered wheel gear-driven device to multiply numerical numbers.

A French man named Blaise Popkal created mechanical calculations in 1642. This device was named Pascalen. Later, in his honor, a modern programming language named Computer has been named Pascal.

Computer does not come at the present stage. There have been many steps to overcome this. In 1951, the first electronic computer Universe (UNIVAC = Universal Automatic Computer) was discovered by the efforts of various mathematicians. After Pascal, in 1671, German mathematician Gottfried Von Leibniz developed a more advanced computing device based on Pascal’s device. Its instrument could have been added by addition. Subtract, multiply, divide and output can be determined.

He first invented the method of multiplying by adding a repetition. In 1801, Professor Charles Babbage tried to create automated calculation instruments for the first time. He named his proposed device Analytical Engine. In 1833, the concept of its planned analytical engine was considered as a form of modern computer. That is why Charles Banks is also called the father of the computer.
