Study Notes
Evolution of Computing Technology
- Understanding the history of computers reveals the impact of technology on society and lessons from past innovations and challenges.
- Modern computing is integral to daily tasks: studying, project preparation, bill payments, entertainment, budgeting, gaming, documentation, banking, office work, online exams, and social media.
Early Computing Devices
- Charles Babbage, known as the "Father of the Computer," invented the first mechanical computer.
- The Abacus, an ancient bamboo frame device, served as an early counting tool using movable beads.
Significant Inventors and Devices
- 1614: John Napier created 'Napier Bones,' a device simplifying multiplication/division through addition/subtraction.
- 1620: Edmund Gunter developed a calculating device featuring a logarithmic scale for quicker arithmetic calculations.
- 1622: William Oughtred invented the slide rule using logarithmic scales for efficient calculations and introduced the multiplication sign (×).
- 1623: Wilhelm Schickard designed the first automatic calculator performing basic arithmetic operations.
- 1642: Blaise Pascal created the first digital computer, known as Pascaline, to aid his father in tax calculations, producing 20 machines and 50 prototypes.
Further Developments
- 1671: Gottfried Wilhelm von Leibniz developed a calculator using a stepped gear mechanism, able to perform all four arithmetic operations.
- The early calculators by Pascal and Leibniz were not widely adopted until later.
Mechanical Tools and Innovations
- Many mechanical tools existed for calculations and measurement, including planimeters and astrolabes.
- The 1770s saw the creation of 'Automata,' dolls capable of writing messages.
Innovations in Programmable Machines
- 1801: Joseph Marie Jacquard invented a mechanical loom using punched cards, paving the way for programmable technologies.
- 1821: Charles Xavier Thomas de Colmar worked on the Arithmometer, the first commercially successful mechanical calculator.
- Between 1822 and 1842, Charles Babbage designed the Difference Engine with funding from the British government.
- 1837: Babbage introduced the Analytical Engine, utilizing punched cards for inputs and capable of printing results.
