Have you ever thought, where did this technology come from and where is the heading? Computers have been around for a very, very, very, long time! Historians have divided the History of Computer into three phases The Dark ages (5000 or 7000 years ago to 1890) The Middle ages (1890 to 1940s) The Modern ages (1940s to date) History of Computers
History of Computers Older computers were analog represent data as variable points along a continuous spectrum of values. More flexible but not necessarily more precise and reliable
Dark Age (5000 or 7000 years ago to 1890) ABACUS – 5000 or 7000 back: The first calculating device ABACUS was invented in Egypt . The abacus is still in use in some countries especially China, Japan Operations Addition, subtraction, division and multiplication Extract square root and cube root User has to memorize certain rules
ABACUS More information on http://en.wikipedia.org/wiki/Abacus
NAPIER’S BONES Invented by a Scottish named John Napier . He first invented the logarithms in 1617 and he got the idea from printed tables. From the printed tables he made an alternative wherein logarithms values are carved on ivory sticks .
SLID E RULE A slide rule can do very difficult calculations engineers and architects were using it before in calculations. Three men developed the slide rule and they were Edmund Gunter, William Oughtred , and Robert Bissaker . It was in 1632 when slide rule was first built in England. It was used in the 1960s by engineers of Mercury, Gemini and Apollo programs which landed men on moon.
PASCALINE 1642: A Frenchman Blaise Pascal introduced the first mechanical calculating device. Series of wheels with teeth which could be turned using hands Used to handle 999,999.99 Perform both addition and subtraction.
L EIBNIZ C ALCULATOR I n 1671 , Gottfried Wilhelm von invented a special stepped gear mechanism for automatic calculation into the business marketplace day and named it Leibniz calculator . Leibniz Calculator had the ability to add, subtract, multiply, and divide using wheels placed at right angles which could be displaced by a special stepping mechanism, it could perform rapid multiplication or division. Likewise Pascaline , the Leibniz Calculator required operator for device who understand how to turn the wheels (Programming Language) of the calculator .
J ACQUARD L OOM In 1804 , French silk weaver Joseph Marie Jacquard invented the Jacquard Loom that simplifies complex designs & calculations . In his loom a series connected Jacuard cards (Punched cards) were passed over needles pressed against the card. Whenever a hole came up the needle would go through the hole activating the threading mechanism and perform an action at end. The Jacquard cards were later modified and evolved into computing punch cards.
Arithmometer Charles Xavior Thomas of France created the first successful mechanical calculator recognized as Arithmometer in 1820 that could add, subtract, multiply and divide. Arithmometer was improved version of earlier inventions. Arithmometer was the first truly successful desktop calculator commercially sold and distributed.
Difference Engine 1833: Charles Babbage Professor of Mathematics Cambridge University With Assistance of Lady Augusta Ada Lovelace developed a machine that could store information, calculate numbers and solve algebraic expression.
Difference Engine
Analytical Engine After Difference Engine, now Babbage want to develop an Analytical Engine, which can perform decimal compute on 50 digits or words and having a storage capacity (memory) of 1,000 digits. Babbage's invented an Analytical Engine in 1833 and soon able to use with punched cards which would be read into the machine from several different reading stations. The machine was supposed to operate automatically, by steam power, and require only one person there. These punch cards were the first true version of a program, as they could be loaded and unloaded from the machine to quickly change from one calculation to another. Babbage inventions are strong base for computing and he is considered as the " Father of Computing ".
Middle Age-(1890 to 1940s) Punched Card 1890: Herman Hollerith American Inventor developed devices that were able to read information which had been punched into cards automatically developed a machine called the census machine US Census Bureau. Capable of reading numbers, characters, and also special symbols.
Punched Cards
Z1 computer Konrad Zuse was a engineer in Aircraft Company in Germany is the inventor of the modern computer for automatic calculators. In 1936 he invented Z1 computer to help in lengthy engineering calculations. One of the most difficult aspects of doing a large calculation with either a slide rule or a mechanical adding machine is keeping track of all intermediate results and using them, in their proper place, in later steps of the calculation. Konrad Zuse wanted to overcome that difficulty. He realized that an automatic- calculator device would require three basic elements: a control, a memory, and a calculator.
A B C C o m p u t er Professor John Atanasoff and his graduate student Clifford Berry built the electronic-digital computer at Iowa State University in 1942 . The Atanasoff -Berry Computer represented several innovations in computing, including a binary system of arithmetic, parallel processing, regenerative memory, and a separation of memory and computing functions.
