Analog computers are a type of computer that uses physical quantities, such as voltage, current, or mechanical position, to represent numerical values. These quantities are manipulated to solve mathematical problems. Unlike digital computers, which represent numbers as discrete binary digits, analog computers operate on continuous values.
Examples of analog computers:
Slide Rule: A slide rule is a simple analog computer used for performing mathematical calculations. It consists of two sliding scales with logarithmic markings. By sliding the scales relative to each other, users can perform multiplication, division, logarithms, and other mathematical operations.
Thermometer: A thermometer is another example of an analog computer. It measures temperature by using the expansion of a liquid or metal. The position of the liquid or metal within the thermometer's tube represents the temperature, which is then read on a calibrated scale.
