Speedometer is an example of ____________ computers.
Correct Answer
C. Analog
Explanation
A speedometer is an example of an analog computer because it measures and displays continuous physical quantities, such as the speed of a vehicle, using a dial or needle that moves along a scale. Analog computers work by representing data as continuous physical variables, such as voltage or current, and performing calculations through the manipulation of these variables. In the case of a speedometer, it converts the rotational speed of the vehicle's wheels into a corresponding analog display on the dial, providing a real-time representation of the vehicle's speed.
