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