Today, you run internet on computer, play games, watch videos, listen to songs and in addition do a lot of office related work, today computers are being used in every region of the world whether it is education, film. Be it the world or your office. Any place is incomplete without a computer. Today, with the help of computers, you can get any information of any city of the world in seconds, from your friends and relatives sitting in another country.
Live video conferencing can be done through internet, all this has been possible due to computer. Imagine what the world would look like today if there was no computer.Where did the computer start and why? Is the computer really built to do all these things or was it invented due to some other reason?
It has been difficult for humans to calculate from the beginning. Human beings can calculate or calculate only to a limited level without any machine. To do a lot of calculations, humans have to depend on the machine itself to fulfill this need. Built computers, that is, to calculate.
Abacus - 3000 years ago :
Abacus was created by Chinese scientists about 3000 years ago. In a rectangular frame, there were wooden tablets in iron rods, which were calculated or calculated from the top down. That is, it was the first computer to run without electricity, in fact it was dependent on your hands to do this work.
Antikythera system - 2000 years ago :
Antikythera was originally an astronomical calculator used to track solar and lunar eclipses in ancient Greece, Antikythera is about 2000 years old, and scientists found it in 1901 from a completely destroyed ship on Antikythera Island Acquired in a chronic-dilapidated state, that is why its name Antikythera system has since been decoded,
This computer has been decoded after long study. This machine works to show the position of the planets as well as the sun and moon in the sky. The Antikythera system received the credit for being the first known analog computer in the modern era, the Greek Antikythera system was developed to correctly estimate astronomical and mathematical data.
Pascaline - 1642 :
Pascaline was built after Abacus. It was made in 1642 by Blaze Pascal, an expert in mathematics, who calculated it faster than Abacus. It was the first mechanical calculator. This machine was called Adding Machine, this Blade Pascal's Adding Machine is also called Pascaline.
Difference Engine - 1822 :
The differential engine was an instrument created by Sir Charles Babbage that could perform calculations accurately, invented in 1822, using punch cards for program storage. It used to run with steam, its basis is being built today computers, so Charles Bawes is called the father of computers.
Jus Z - 3 - 1941 :
The great scientist "Conard Juice" invented the "Zuse-Z3" salt, an amazing device that was the first electronic computer based on Binary Arithmetic and Floating point Arithmetic.
Eniac - 1946 :
A US military research room built an "ENIAC" machine meaning Electronic Numerical Integrator And Computer. "ENIAC" worked on the Decimal Arithmetic system, later "ENIAC" first became known as computer which later evolved into modern computer.
Manchester Small Scale Machine (SSEM) - 1948 :
(SSEM) was the first computer that could protect any program in a vacuum tube, its nick name Baby was placed, it was made by Frederick Williams and Tom Kilburn
