The Major Difference Between Analog and Digital Computer is that Analog Computers Provide continuous value and represent the physical quantities in the form of waves or in continuous forms while Digital Computers provide discrete value and represent physical quantities with the help of symbols or numbers.
Difference Between Analog and Digital Computer in Tabular Form
|Analog Computer||Digital Computer|
|It represents data continuously.||It represents data discretely as 0s and 1s.|
|It is used to measure physical values such as temperature and pressure.||It converts the data into digits then performs all types of operations on these digits.|
|3. Signal Types|
|Type of signal is continuously varying electromagnetic wave.||Type of signal is the sequence of voltage pulses over time.|
|Means of transmission of analog signals are without regard to their content.||Means of transmission is concerned with the content of the signal.|
|It has no memory and computing devices.||It has memory and solves problems by counting precisely.|
|It adopts physical devices to measure continuously variable data e.g. in thermometer temperature is measured by the expansion of mercury.||It gives written outputs at extremely fast rates with high accuracy.|
|It has no output and input devices.||It has input and output devices.|
Examples of the analog computer are:
Thermometer, barometer, Speedometer of cars, voltmeter, ammeter etc.
|The IBM PC and all other personal computer belong to digital computers.|
|Measurement of different physical quantities, scientific applications.||Business, science, and home.|
