Historical Background Simple Chronically of events which leads to development of modern computers/processors

I. Pre-Computers : Mechanical Age

• Use of mechanical devices for computation  “ The Abacus “ - Babylon? Chinese? 1000 – 500 BC  (^) Leonardo da Vinci 1500s (?) - Notes  (^) Wilhelm Schickard: Calculating Clock “ in 1623. (?)- Letter  (^) Blaise Pascal : mechanical calculator in 1642 – Adds, Substract 8 digit  (^) Gottfried von Leibniz : upgrade of Pascal device ( +,-,*,/)  (^) Charles Babbage 1820 : Difference Engine ( British Army )  (^) - a steam-powered mechanical computer to perform various calculating tasks - 1832 : Analytical engine : Punch card system for output , perform simple condition ( not complete; reconstructed based on notes )

Historical Background II – Mechanical Age Analytical Engine The Babbage Difference Engine(1832) 25,000 parts cost: £17, Analog to modern computers

( fundamentals of computer

programming, including data

analysis, looping and memory

addressing. )

Use punch card system for

programming and output result

ENIAC

First Transistor  (^) How does the ENI1947 becomes smaller? Limitation of electron tubes – invention of the TRANSISTOR  1947 John Bardeen and Walter Brattain -> “transistor,”

Transistors  (^) Z3 - Konrad Zuse 1941, an electrical driven mechanical calculators at 5.33Hz  (^) Z3 later evolved to Z4 – the first commercial product
