  1. Information Age “An in depth look at the exciting history of the Calculator and Computer”

  2. Abacus • Pascal • Leibniz • Babbage • Early Computers • Electronic Computers • Transistor • Personal Computer • Advancements • Noteworthy Contributors

  3. Abacus • 5,000 years ago • Asia Minor • 5-bead

  4. Blaise Pascal • Pascaline • Numerical wheel • Invented 1642 • Add & subtract only • Series of ten-toothed wheels • 6, 8 ? • Each tooth represented a digit • 0 to 9

  5. Gottfried Wilhelm Von Leibniz • Philosopher and mathematician • 1649 • Improved Pascaline • Multiply and divide • Birth • Calculator • Personal computers ?

  6. Charles Babbage • Difference Engine • With Augusta Ada King • First actual computer • Stores information • Accepts data
