Study Notes
History of Computing
- The term "computer" was first used in 1613 to describe a person who performed calculations.
- The earliest computers were humans, whose job was to perform calculations.
- Calculations were specialized and expensive, requiring years of training.
Early Calculating Devices
- Tally Sticks: An ancient device for recording numbers and quantities.
- Abacus: A mechanical device for performing basic arithmetic, invented in Babylonia around 2400 B.C.
- Napier's Bones: Invented in 1614, used for multiplication, division, and calculating square and cube roots.
- Slide Rule: Invented in 1622, based on logarithms and used for multiplication, division, roots, logarithms, and trigonometry.
- Pascaline: Invented in 1642, limited to addition and subtraction and was expensive.
- Stepped Reckoner: Invented in 1672, capable of adding, subtracting, multiplying, and dividing automatically.
- Jacquard Loom: Invented in 1881, an automatic loom controlled by punched cards.
- Arithmometer: Invented in 1820, the first reliable, commercially successful mechanical calculator, capable of performing the four basic arithmetic functions.
- Difference Engine and Analytical Engine: Invented by Charles Babbage in 1822 and 1834 respectively. The Difference Engine was designed to tabulate polynomial functions while the Analytical Engine is considered the first mechanical computer.
- Scheutzian Calculation Engine: Invented in 1843, based on Babbage's Difference Engine and the first printing calculator.
Early Computers
- First Computer Programmer: Augusta Ada Byron, who suggested using the binary system and wrote programs for the Analytical Engine.
- Tabulating Machine: Invented in 1890 for summarizing information and accounting.
- Harvard Mark 1: Invented in 1943, the first electro-mechanical computer.
- Z1: Created by Konrad Zuse from 1936 to 1938, the first programmable computer, using punch tape for input and output.
- Atanasoff-Berry Computer (ABC): Invented between 1939 and 1942, the first electronic digital computing device.
- ENIAC (Electronic Numerical Integrator and Computer): Completed in 1946, the first electronic general-purpose computer, developed by John Presper Eckert and John Mauchly.
- UNIVAC 1: The first commercial computer, designed by John Presper Eckert and John Mauchly.
