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.
