Tic History of Computer ABACUS Also called a counting frame, is a calculating tool used primarily in Parts of Asia for performing arithmetic processes.

The Abacus is really just a representation of the human fingers: he 5 lower rings on each rod represent the 5 fingers and the 2 upper rings represent the 2 hands. Nipper’s Bones Nipper’s bone was invented by John Napier (1550-1617), a Scottish mathematician and scientist. Nappies bone was multiplication tables written on strips of wood or bones. The invention was used for multiplying, dividing, and taking square roots and cube roots. Slide Rule William Ought made the first slide rule by inscribing logarithms on wood or ivory. Before the invention of the pocket or handheld calculator, the slide rule was a popular tool for calculations.

The SE of slide rules continued until about 1 974, after which electronic calculators became popular. Passerine ( First Mechanical calculator) Invented by the French Mathematician named Blaine Pascal (1642) first called Arithmetic Machine, Pascal’s Calculator and later Passerine. It can add and subtract long columns of numbers without making a mistake. Leibniz its Calculator Invented by Gottfried Wilhelm Leibniz a German Mathematician (1 805), this Machine can add, subtract, multiply, and divide numbers and it could also find the square roots of numbers. Jacquard Weaving Loom Another Frenchman named

Joseph-Marie Jacquard invented weaving loom (1805). It follows instruction from the Punch cards that are fed to the loom to create patterns Non cloth-and Analytical Engine Difference Charles Babbage designed “Difference Engine” in 1822. An English Mathematician named Charles Babbage invented this machine (1883). To build the analytical engine, thousands of tiny parts had to be made perfectly. At that time , no machine could create parts so small and exact. Because of that , analytical engine was never built. But because of Charles Babbage idea, he became known as “Father of the Modern

Computer”. A decade later, Lady Augusta Dad Byron presented the idea that Punch cards could be used to instruct Baggage’s engine to perform certain repetitive instructions. So because of this, she was popularly known as the “First Programmer”. Hellebore’s Punch Cards The government created a contest to find the best solution to the problem. In 1890 it was won by a census agent named William Hollering. In his design, each census form was encoded into a punch card. Machine called ‘tabulators” could rapidly process stacks of these cards.
