Study Notes
Definition of Computer
- A computer is an electronic device that manipulates information and is a programmable machine that has the ability to store, retrieve, and process data.
History of Computers
- Abacus: a mechanical device used to aid in performing mathematical calculations, invented in Babylonia in 500 BC, used to perform basic arithmetic operations.
Early Computing Machines
- Pascaline: invented by Blaise Pascal in 1642, it could only perform addition and subtraction, and was too expensive.
- Z1: the first programming computer, created by Konrad Zuse in Germany from 1936 to 1937, used punch tape.
- Colossus: developed by Alan Turing in 1943, was the first electronic computer, but not programmable.
- ENIAC: Electronic Numerical Integrator & Computer, the first electronic general-purpose computer, developed by John Presper Eckert and John W. Mauchly in 1946.
- UNIVAC 1: the first commercial computer, developed by J. Presper Eckert and John Mauchly.
Other Important Machines
- Stepped Reckoner: invented by Gottfried Wilhelm Leibniz in 1672, could add, subtract, multiply, and divide automatically.
- Jacquard Loom: a mechanical loom, invented by Joseph-Marie Jacquard in 1801, controlled by punched cards.
- Difference Engine: an automatic calculator designed to tabulate polynomial functions, invented by Charles Babbage in 1822 and 1834, the first mechanical computer.
- Analytical Engine: suggested by Augusta Ada Byron to use the binary system, and she wrote programs for the Analytical Engine in 1840.
