The computer is an integral part of many people’s lives today. But it was not always so. It took scientists several centuries to create what we today call a computer.

The first prototype of a computer appeared in 1623. It was then that the German scientist Schickard created an apparatus that could perform addition and subtraction. A little later, the Frenchman Blaise Pascal invented the same apparatus, but with the ability to do more multiplication and division. The basis of such an adding machine was a gear wheel.

American scientist Herman Hollerith in 1890 invented a machine that worked with tables (exel prototype). In the same year, it was used in the US census.

For the first time the binary system was embodied in the operation of the machine by the German Konrad Zuse. It happened in 1938.

The next turning point in the history of computers was the invention of the microprocessor by Intel. At first, it could only perform four mathematical operations, so it was used only in calculators. A little later, the company improved the microprocessor, it could already be used to create a computer. It was the Intel microprocessor that was used by the young Bill Gates when creating his program in the Basic programming language.

No less important was the creation of a microprocessor, thanks to which the computer could execute several programs at once. It happened in 1985, and in 1993 the Intel Pentium microprocessors appeared. The creation of the Pentium Pro processor made it possible to produce not only large and expensive computers, but also cheap PCs for the mass consumer.

The first computers in the USSR appeared in the early 80s. The first serial computer was “Electronics BK-0010”. Many other electronic computers were also created, but due to competition from the Westотечественные компьютеры не смогли найти своего места на рынке.
