In the field of signals provided to transmit signals, we can find two different ways, analog and also digital, both use electricity, but in various ways. The major Difference in between Analog and also Digital computer is the Analog computer systems Provide consistent value and represent the physical amounts in the form of tide or in consistent forms when Digital Computers provide discrete value and represent physical amounts with the aid of signs or numbers. 


Difference between Analog and also Digital computer in Tabular Form

Analog ComputerDigital Computer
It to represent data continuously.

You are watching: What is the difference between analog and digital computers

It to represent data discretely together 0s and also 1s.
2. Operation
It is supplied to measure physical values such together temperature and pressure.It counter the data right into digits climate performs all species of work on this digits.
3. Signal Types
The form of signal is repeatedly varying electromagnetic waves.The kind of signal is the sequence of voltage pulses over time.
Means of infection of analog signals space without regard to their content.Means of transmission is concerned with the content of the signal.
It has actually no memory and also computing devices.It has memory and solves problems by count precisely.
It by physical devices to measure consistently variable data e.g. In thermometer temperature is measured by the growth of mercury.It offers written outputs at incredibly fast prices with high accuracy.
7. Devices
It has no output and also input devices.It has actually input and output devices.

Examples the the analog computer are:

Thermometer, barometer, Speedometer of cars, voltmeter, ammeter, etc.

The IBM PC and all other personal computers belong to digital computers.
Measurement of different physical quantities, scientific applications.Business, science, and home.

In analog technology, the electric signals space converted into electrical impulses of varying amplitude and also in digital technology, it transforms them into data in binary setting (0 and also 1), wherein each little bit represents two various amplitudes.


It is any constant signal for which the personality of a variable represents a qualitative characteristic. Use a set of worths ​​to stand for the information.

Analog signals experience from alterations that cause communication errors. The copies in the communication are no as great quality as in the original.

If you desire to stand for a change analog worth digitally, quantization errors have the right to occur.


Use continuous-discrete values. Represent info discreetly, with letters and numbers, or continuously, v sounds, images, or various other indicators.

Employs details timing order to identify communication. In addition, it needs that the language be understood by both who sends the message and who receive it. The symbols used must have actually a details meaning.

Copies of digital interactions are as good quality as the original.

Differences in between analog and also digital

Analog modern technology is cheaper than digital.Data in digital modern technology is converted right into binary code and then transformed into its original form on the receiving equipment.Analog an innovation represents info with the indicators of human being communication.
