history of computer To count large numbers, the history of computers can be seen back in the efforts of humans. This process of counting large numbers generated different systems of numbers such as the Babylonian system of numbers, the Greek system of numbers, the Roman system of numbers and the Indian system of numbers. Of these, the number of Indian systems has been universally accepted. This is the basis of the modern decimal system of numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). As we know, the computer is not able to understand the decimal system and uses the number of binary system for processing. We will briefly discuss some path breaking inventions in the field of computing devices.
1. Calculation of Machines: Generations were taken to create mechanical devices to count large numbers for beginners. The first counting device named Abacus was developed by Egypt and Chinese people. Abacus word means to calculate the board. In this horizontal conditions there are rods on which pebbles are inserted. It consists of several horizontal bars, each having ten pearls. Horizontal bars represent units, tens, hundreds, etc.
2. Napier's bones: English mathematician John Napier created a mechanical device for the purpose of multiplication in 1617 AD. The device was known as Napier's bones.
3. Slide Rules: English mathematician Edmund Gunter developed slide rules. This machine can operate like extra, subtraction, multiplication, and division. It was widely used in Europe in the 16th century.
4. Pascal's Joint and Subtraction Machine: You must have heard the name of Blaze Pascal. He developed a machine at the age of 19 that can add and subtract. The machine included wheels, gears and cylinders.
5. Multiplication and division of Leibniz: German philosopher and mathematician Gottfried Leibniz builds a mechanical device around 1673, which can be both multiplied and divided.
6. Analytical Engine of Babbage: It was in 1823, that a famous Englishman, Charles Babbage, created a mechanical machine to perform complex mathematical calculations. It was called the inter-engine. Later, he developed a simple calculation machine named Analytical Engine, You should know that Charles Babbage is called the father of computer.
7. Mechanical and Electrical Calculator: At the beginning of the 19th century the mechanical calculator was developed for all types of mathematical calculations and it was widely used for the 1960s. Later the regular part of the mechanical calculator was replaced by electric motor. It was called electric calculator.
Modern Electronic Calculator : The electronic calculator used in the 1960s was carried out with electron tubes, which was quite heavy. Later it was replaced with the transistor and the resulting calculator size became too small. Modern electronic calculators can calculate all kinds of mathematical computations and mathematical operations. It can also be used to store some 7 data permanently. Some calculators have built-in programs to perform some complex calculations.
1813 AD - Inter-Engine - Charles Babbage - England: In the beginning of the 19th century, an Englishman Charles Babbage was working on the development of a machine, which could make complex calculations. In 1813 he invented the 'inter engine' which Could perform complicated calculations and print them as well. This machine was a steam powered machine.

Computer development
1600 AD - Napier Bonus: Another counting device is Napier Bones, "John Napier, a Scottish mathematician, invented it." Bones "were the ivory strips that were with numbers written in them, when the bones are systematically arranged. To get the answer to a qualitative operation, the user can read the numbers in the adjacent column.1642 AD-Adding Machine- Blaise
Pascal- Appreciation: The famous French scientist and mathematician, Blaze Pascal invented the first machine that can be added, can automatically take points. He was only nineteen years old at that time. His machine was so revolutionary that the principle behind it is still used in most machine counters used today.
16 9 2 AD-Majority Machine - Coptriot Libitis - Germany: Gottfried Pascal improved on the machine and introduced a mechanism to cater to the automatic multiplication of numbers. In developing Leibnita's branch of mathematics, Sir Isaac Newton, best known for his work, is best known for his work. He can accurately add, subtract, multiply and divide the desired calculator. This square can also do the routing function, although it is not always accurate.
1813 AD - Inter-Engine - Charles Babbage - England: In the beginning of the 19th century, an Englishman Charles Babbage was working on the development of a machine, which could make complex calculations. In 1813 he invented the 'inter engine' which Could perform complicated calculations and print them as well. This machine was a steam powered machine.

At the beginning of the nineteenth century, a French Weaver Joseph Mary jacquard developed a programmable loom, which used large cards and holes to automatically control the pattern. Output was double rich texture, with a repetitive floral or geometric pattern. |
