Analog computers operate on continuous quantities like voltage and pressure, and can only approximate results, while digital computers use binary numbers ("0" and "1") for exact results and are faster. Hybrid computers combine aspects of analog and digital by facilitating conversion between analog and digital formats to leverage the strengths of both.

2.  Analog computers
 Digital computers
 Hybrid computers

3.  Analog is a computing device.
 Works on continuous range of value.
 Only be approximate.
 Deals with quantities that vary continuously.
 Deals with physical variables.
 Such as voltage, pressure, speed etc.

4.  Operate on digital data such as number.
 Uses binary number system.
 Only two digit 0 and 1.
 Each one is called a bit.
 Designed using digital circuits.
 Two levels for an input and output signal.
 More accurate and faster result

5.  Solving complex problems .
 Increasing use in the field of design, research
and data processing.
 Based on the purpose.
1. General purpose computer
2. Special purpose computer

6.  Special is one that is built for a specific
application.
 General used for any types of application.
 Store different programs.
 Jobs as per instruction specific program.

7.  Combines the desirable feature of analog and
digital.
 It is more automatic operation.
 Physical and machine process.
 Analog to digital and digital to analog.
 Used to transforming the data.
