Study Notes
Early Computing Devices
- The abacus, invented in China around 1602, was the first mechanical calculating device.
- Napier's Bones, from 1617, used a three-dimensional structure for multiplication.
- Pascaline, invented in 1642 by Blaise Pascal, was the first mechanical adding machine, used for basic arithmetic.
Key Inventions in Computer History
- Jacquard's Loom (1801): Used punched cards to automate textile weaving. This paved the way for using structured data to control machinery.
- Analytical Engine (1837), Charles Babbage: A first conceptual general-purpose computer, designed but never fully built. It stored programs on pegs.
- Tabulating Machine (1890), Herman Hollerith: First electromechanical machine for larger-scale data processing like the US Census. Used punched cards.
- MARK-1 (1944), Howard Aiken: Used magnetic drums for storage and was used for military and scientific calculations during WWII.
- ENIAC (1946), J.P. Eckert and J.W. Mauchly: First electronic digital computer, using vacuum tubes for logic and capable of complex calculations.
- EDSAC (1949), John Von Neumann: First computer with the ability to store both data and instructions, using mercury delay lines and vacuum tubes.
- UNIVAC (1951), J. Presper Eckert and John Mauchly: First general-purpose electronic computer for business use, using magnetic tapes for input/output.
- IBM-650 Computer (1953), IBM: A general-purpose computer for business, science, and engineering, that featured special characters to decimal conversions and data input/output units.
Fundamental Computer Characteristics
- Automation: Computers can perform tasks without human intervention.
