1. Abacus (3000 BC) First known counting device Used for basic arithmetic operations 2. Napier’s Bones (1617) Invented by John Napier Helped perform multiplication and division 3. Pascaline (1642) Invented by Blaise Pascal First mechanical calculator 4. Stepped Reckoner (1673) Invented by Gottfried Wilhelm Leibniz Could add, subtract, multiply, and divide 5. Difference Engine (1822) Invented by Charles Babbage Designed to solve mathematical calculations automatically 6. Analytical Engine (1837) Also by Charles Babbage Considered the first concept of a modern computer 7. Tabulating Machine (1890) Invented by Herman Hollerith Used punched cards for data processing 8. First Generation Computers (1940–1956) Used vacuum tubes Example: ENIAC Very large and expensive 9. Second Generation Computers (1956–1963) Used transistors Faster and more reliable 10. Third Generation Computers (1964–1971) Used integrated circuits (ICs) Smaller and cheaper computers 11. Fourth Generation Computers (1971–Present) Used microprocessors Development of personal computers (PCs) 12. Fifth Generation Computers (Present & Future) Based on Artificial Intelligence (AI) Includes robotics, machine learning, and smart systems Design Ideas You may: Use arrows or lines to connect events Add pictures/icons of old computers Use different colors for each generation Make it horizontal or vertical timeline style Example layout: Abacus → Pascaline → Difference Engine → ENIAC → Personal Computers → AI Computers
