Study Notes
Inventions and Innovations in Computing
- Arithmometer: Mechanical calculator by Thomas de Colmar (1820), first reliable device for basic math operations, and mass-produced.
- Difference Engine: Created by Charles Babbage (1822), first mechanical computer designed to tabulate polynomial functions automatically.
- First Computer Programmer: Augusta Ada Byron promoted the binary system to Babbage in 1840 and wrote programs for his Analytical Engine.
- Scheutzian Calculation Engine: Developed by Per Georg Scheutz (1843), the first printing calculator based on Babbage's Difference Engine.
- Tabulating Calculator: Invented by Herman Hollerith (1890) for data summarization and accounting tasks.
- Harvard Mark 1: Also called IBM ASCC, created by Howard H. Aiken (1943), recognized as the first electro-mechanical computer.
- Z1: Konrad Zuse's creation (1936-1938), regarded as the first programmable computer utilizing punch tape for input/output.
- Atanasoff-Berry Computer (ABC): First electronic digital computing device, co-developed by John Atanasoff and Clifford Berry (1939-1942).
- ENIAC: First electronic general-purpose computer, developed by John Presper Eckert and John Mauchly, completed in 1946.
- UNIVAC 1: First commercial computer designed by Eckert and Mauchly.
- EDVAC: First stored program computer designed by Von Neumann (1952), capable of holding programs and data in memory.
- OSBORNE 1: First portable computer released in 1981.
Historical Context of Computers
- Early Computers: Humans termed "computers" performed calculations, which were specialized and required extensive training.
- Tally Sticks: Ancient devices used for recording numbers and quantities.
- Abacus: Mechanical device from Babylonia (2400 B.C.), later familiar in China (500 B.C.), utilized for basic arithmetic.
- Napier’s Bones: Created by John Napier (1614), allowed calculations like multiplication and square roots using rods.
- Slide Rule: Invented by William Oughtred (1622), primarily for multiplication, division, and logarithmic calculations.
- Pascaline: Blaise Pascal's invention (1642) that could only perform addition and subtraction.
- Stepped Reckoner: Created by Gottfried Wilhelm Leibniz (1672), capable of automating addition, subtraction, multiplication, and division.
- Jacquard Loom: Mechanical loom by Joseph-Marie Jacquard (1881), the first to use punched cards for automation.
Generations of Computers
- First Generation (1946-1958): Utilized vacuum tubes leading to high costs, heat generation, and large size. Supported batch processing and machine code.
- Second Generation (1959-1964): Introduced transistors, smaller size, less electricity, and heat. Used magnetic core memory for faster processing.
- Third Generation (1965-1970): Featured integrated circuits (IC), higher performance, and lower maintenance costs, widely used in business and research.
- Fourth Generation (1971-2010): Microprocessor technology enabled portable and affordable computers with faster computation and greater accessibility.
- Fifth Generation (2010-today): Based on AI, quantum computing, and parallel processing, characterized by speed, multitasking, and low power consumption.
Future of Computers
- Positive outcomes may include advanced AI capabilities, improved efficiency in various sectors, and broader accessibility of technology.
- Negative implications could involve ethical concerns in AI usage, job displacement due to automation, and increased reliance on technology impacting personal skills.
