Electronic computation:

  • The movement of electrons in an electronic computing device performs the same function as the movement of gears and wheels in a mechanical computing device.
  • The computational functions performed within an electronic circuit can be determined by mathematical relationships among the components and electron flow.
  • Electronic devices are faster because of high speed of moving electrons.
  • Electronic computers make it faster to perform complex calculations.

Optical computation:

  • In optical devices, a moving photon’s energy can perform computational work.
  • A particle of light known as a photon moves at a high rate of speed.
  • Optical discs are used to store large video files.
  • Some input/output devices are based on optical technologies and devices.
