Study Notes
Early Computing Technologies
- Punched card technology: Introduced to control weaving operations, allowing for programmable patterns.
- Jacquard's Loom: Revolutionized weaving by utilizing punched cards tied together in a loop, each card representing a thread to be woven.
- Charles Babbage: Known as the "Father of Computers" for his pioneering designs of the Difference Engine and Analytical Engine.
- Difference Engine: Designed to aid in mathematical table calculation for navigation.
- Analytical Engine: More ambitious than the Difference Engine, envisioned with punched card input, a memory unit (store), an arithmetic unit (mill), automatic printout, sequential program control, and 20-place decimal accuracy.
- Ada Lovelace: Daughter of Lord Byron and a brilliant mathematician, documented Babbage's work.
- She translated and added notes to an Italian mathematician's memoir on the Analytical Engine, outlining its potential for calculations like Bernoulli numbers.
- Napier's Bones (1614): John Napier invented logarithms and inscribed logarithmic measurements on wooden rods to aid multiplication and division.
Early Calculating Devices
- The Slide Rule (1621): Invented by William Oughtred, it used logarithms inscribed on wooden strips to perform multiplication, division, and other calculations.
- Pascaline (1642): Designed by Blaise Pascal, this mechanical device could perform addition and subtraction using gears with 10 teeth representing numbers 0 to 9.
- Leibniz's Wheel (1673): Gottfried Wilhelm von Leibniz invented a calculating machine that could add, subtract, multiply, and divide through repeated additions or subtractions.
- He also invented binary arithmetic, a crucial concept for modern computers.
The Evolution of Computing
- The Abacus: An ancient calculating tool that is still in use today. The abacus, also called a counting frame, is a calculating tool used primarily in parts of Asia for performing the arithmetic process.
- Modern Definition of a Computer: An electronic device that accepts data, processes it, produces results, presents results to users, and stores results for future use.
- Data vs Information:
- Data: Unorganized facts and figures that lack context or patterns.
- Information: Organized and meaningful data that has been processed.
Overview of Computer History
- Early humans relied on counting on fingers, stones, notched sticks, knotted cords, and symbols to keep track of their belongings.
- Industrial Age (1600s): The mechanical calculating machine was invented, marking the beginning of a new era for computing.
- ITEINC (Introduction to Computing): Course aims to explain fundamental principles, concepts, and evolution of computing systems, demonstrate applications of computers in society, and teach basic web page design.
