Difference between Analog computer and digital computer

Analog computer Vs Digital computer

Computer is an electronic data processing and calculating machine which takes raw data as input, process them and gives meaningful information as output. Analog and digital computer are the types of computer based on work. the difference between analog and digital computer are given below:

Difference between Analog and Digital computer

Parameter	Analog Computer	Digital Computer
Definition	Computer that works on continuously variable data.	Computer that works on discrete data based on binary data.
Uses	Used to measure physical quantity like voltage, current, pressure, etc.	Used to process digital or input data.
Complexity	Complex to use.	Ease to use.
Reliability	Lower reliability.	Higher reliability.
Accuracy	Lower accuracy in output.	Higher accuracy in output.
Power consume	Power consumption is high.	Power consumption is low.
Speed	Speed of processing is slower than digital computer.	Speed of processing is faster than analog computer.
Purpose	It is special purpose computer.	It is general purpose computer.
Storage	Low or limited public memory and store less data.	Large memory and able to store large amount of data.
Symbol
Example	Analog balance, analog clock, thermometer, speedometer, voltmeter,etc.	Desktop, laptop, smart phones, digital watch, digital camera, etc.

 Therefore, Analog computera are best for measuring physical quantity like voltage, current, pressure, speed, etc and widely used in scientific and industrial uses, while digital computers are best for measuring digital data based on 0 & 1 and widely used in personal uses, home, office and college.
