Difference Between Analog and Digital Computer

Digital ElectronicsComputersData Storage

In this post, we will understand the difference between analog computer and digital computer −

Analog computer

  • It works with continuous values, i.e they process continuous data.

  • The speed of such computers is less than that of digital computers.

  • It has very less memory, and can store limited amount of data.

  • It doesn’t have any state.

  • They are not as reliable as digital computers.

  • It doesn’t provide performance as good as digital computers.

  • Its processing speed is low.

  • It depends on physical variations.

  • The results given by analog computers have very less accuracy.

  • They are not easy to use.

  • They have a complex architecture.

  • It has low readability.

  • The results of analog computers are given out as voltage signals.

  • They use analog encoding.

  • They use special purpose devices.

  • They consume more power.

  • Examples includes analog clock and thermometer.

Digital computer

  • They work with discrete values, i.e they process discrete data.

  • The speed of digital computers is more in comparison to analog computers.

  • It has more memory space, hence stores large amounts of data.

  • It has two steps: On and Off.

  • It is more reliable.

  • It provides great performance.

  • Its processing speed is high.

  • It doesn’t depend on physical variations.

  • They are easy to use.

  • The results are more accurate.

  • Their architecture is not as complex as analog computers.

  • They have high readability.

  • The results are displayed on the monitor/display screen.

  • They use digital encoding technique.

  • They consume less power.

  • It can be used as a general purpose device.

  • Examples include laptop, digital camera, digital watches.
