History Of Computer

Friends, do you know that the use of the computer word has been used before the creation of a computer. In the past, the operator of any calculating machine was called "computer". The history of computer has been around 3000 years old today. Calculating for human being has been a difficult task since at least. With the help of no electronic machine, man can count only a limited number. In order to make bigger calculations, man has to depend on the machine. Therefore, to meet this need, man created the computer.

An instrument was created to calculate the first order in China about 3,000 BC. This device was named Abacus. ABACUS was the first to calculate. There are many rods in this machine, where round shaped grains were used to which can be lowered. With the help of which the work of adding and subtracting numbers was done. But ABACUS could not be multiplied and divided. This was the first part of the development process of our modern computer.

The time between 1600 and 1970 was very important in the history of computer. Modern computers were developed during this period.

After this, in 1622 William Oughtred invented a device called "slide rule". Slide rule is a mechanical analog computer. With the help of this machine it is done for multiplication, division, root and trigonometry whereas the work of adding and subtracting can not be done with the help of slide rule. This device was also a part of the gradual development of the computer.

Pascaline was formed after Abacus. In 1642 it was made by French mathematician Blaise Pascal. It used to calculate faster than Abacus This was the first mechanical calculator of its kind. This machine was called Adding Machine. This machine could work to add up to 10, 100, 1000 points.

In 1672 E. Gottfried Wilhelm Leibniz, a scientist, had created a calculator machine named "Leibniz Stepped Reckoner". Which could do all kinds of calculations such as adding, subtracting, multiplication and division. It was an invention that gave a new dimension to the development of the computer.

So far as the invention of the computing machine was in the making, it was hundreds of years away from modern computers. Science progressed and in 1822 CE, a famous scientist, "Charles Babbage," created a modern C machine. The name of this machine was "Difference Engine". It was a modern design of mechanical computer.

After that in 1837, Charles Babbage created another machine named "Analytical Engine". This was an automated mechanical calculator with steam. It was able to do calculations in exactly the right way. Based on this, many of today's computers are working. However, he could not complete this project due to lack of funds. And their project was completed by "Harther Hollerith" Because this project was designed by Charles Babbage. That's why they are called the father of modern computers.
