very first computing devices had their own human fingers.When this tool is not enough, in the course were pebbles, sticks, shells.Adding a set of tens and then hundreds, people learned to read and to use the means of measurement numbers.It is with pebbles and shells began the history of computing.Expanding them on different columns (level), and adding or removing the desired number of stones, could make the addition and subtraction of large numbers.Repeated addition it was possible to perform even a complex action as multiplication.
Then begins the history of the development of computer technology.First means for computing was the invention of the abacus in Russia.They were divided into dozens of using horizontal guides from bones.They have become an indispensable tool merchants, bureaucrats, clerks and managers.These people know how to use by simply masterly.In the future, such a device you want, and penetrated into Europe.
very first mechanical device to account, who knows the history of computing, began counting machine, which in 1642 built a prominent French scientist Blaise Pascal.Its mechanical "computer" could produce things such as addition and subtraction.This machine called "Pascaline" and it consisted of a complex, which is installed vertically wheels with applied numerals from 0 to 9. The wheel at full back cling adjacent wheel and turn it to a single digit.Number of wheels determined number of bits computer.If it adjusted to five wheels, it could have carried out the operation with a large number up to 99999.
Then in 1673 a German mathematician Leibniz created a device that could not only add and subtract but also multiply and divide.Unlike machines Pascal wheels were jagged and had nine different lengths of teeth, and this make such incredible "complex" acts as multiplication and division.The history of computing know many names but one name is known even to non-specialists.This English mathematician Charles Babbage.His deservedly called the father of all modern computers.That he belongs to the idea that you need a computer device that will store the number.Moreover, this device should not only store the number, but also give commands to a computer that it should do with these numbers.
Babbage's idea and became the basis of the device and the development of all modern computers.Such a block is called a computer processor.However, the scientist does not have any drawings and descriptions of the car, which he invented.It made one of his disciples in his article, which he wrote in French.Articles Read the Countess Ada Lovelace August - the daughter of the famous poet George Byron, who translated it into English and has developed this machine for their own programs.Thanks to the history of the development of computer technology has received one of the most advanced programming languages - ADA.
XX century gave a new impetus to the development of computer technology related to electricity.It was invented by an electronic device that stores electrical signals - tube trigger.Created with the help of the first computers could count a thousand times faster than the most advanced mechanical calculating machines, but they were still very cumbersome.The first computers weighed about 30 tons and occupied the premises larger than 100 square meters.meters.Further development of computers received with the advent of extremely important inventions - the transistor.But modern computer technology would be unthinkable without the use of a microprocessor - a complex integrated circuit, developed in June 1971.Such is the brief history of computing.Modern science and technology have raised the level of modern computers to unprecedented heights.
