Computing Speed

• Current personal computers can do 100 million
  calculations per second.
• The most powerful computer, like ASCI White, can
  reach 12 trillion calculations per second.

Mechanical Computers

• Charles Babbage designed the first mechanical
  computer, which was composed of gears and shafts,
  in early 1800s to compute the chart of logarithm.
