What is Analog computer?

 The term ‘Analog’ means continuous wave or data such as electronic current and any device, which measures this continuous data by some system of unit such as speed, pressure etc., these types of computers are involved in industrial process controls and measure physical quantities. These computers do not use binary digits but use electrical resistance , voltage , etc. These electrical properties allow calculations to be performed in real time or even faster than the speed of light. The main mathematical operations it applies include summation, inversion, exponentiation, logarithm, integration, differentiation, multiplication and division.

Example of analog devices are:- speedometer of an automobile, voltmeter, etc. analog computers are specific-purpose devices. They are very fast in operation because all the measurements are achieved in truly parallel mide, i.e. they can perform several calculations at the same time.
