Why Did Early Computers Use Vacuum Tubes?

šŸ’” The Answer

  • Vacuum tubes acted as switches and amplifiers before transistors existed.
  • They controlled electron flow in a vacuum to represent binary states.
  • Tubes were fragile, generated massive heat, and consumed a lot of power.
  • The ENIAC computer used 17,468 vacuum tubes and weighed over 27 tons.
