Study Notes
- Computers have undergone two primary development stages: mechanical and electronic
- Mechanical computers predated 1945, utilizing mechanical or electromechanical components
- Ancient Chinese abacus (500 BC) is an early example of a mechanical computer
- Blaise Pascal created a mechanical adder/subtractor in France (1642)
- Charles Babbage designed England's difference engine for polynomial evaluation (1827)
- Konrad Zuse built the first binary mechanical computer (Germany, 1941)
- Howard Aiken proposed the first electromechanical decimal computer (Harvard Mark I, IBM, 1944)
- Both machines were designed for general-purpose computations
- Electronic computers have experienced five generations of development
- First three generations spanned approximately ten years each
- Fourth generation lasted fifteen years
- We've entered the fifth generation with processors and memory devices with over 1 million transistors.
