what is analog in computer

Best answer


An Analog computer is acomputer which uses continuously changeable entitieslike mechanical, electrical, hydraulic, etc. These were first used at the time of the 1950s鈥?960s. They do not use discrete values but use continuous values.

  • Why do we use analog computers?

  • Analog computers can store analog data in the continuous physical quantities likes as electrical potential, fluid pressure, or mechanical motion, and finally it produces the result with using of measures. Analog computers are used in such areas, where to need data to be measure directly without transforming into numbers.

  • What is an analog signal?

  • Analog or analogue is an electronic communication sent as signals of varying frequency instead of ON or OFF like a digital data transmission. Analog allows equipment to handle information that continuously changes such as voltage, current, and wave. The picture is an example of an analog signal or how analog may be represented.

  • What is the difference between analog and digital input and output?

  • Input can be performed in personal computer in form of letters, numbers and with binary coded languages. 鈥?Digital computer shows result in form of monitor or other output devices while analog computer shows results in the form of voltage signals.

  • What is the difference between a calculator and an analog computer?

  • (An abacus was still cheaper and faster.) Analog computers, in contrast, are devices in which continuous quantities, such as electrical potential or mechanical motion, are used instead of discrete (e.g., on/off) states. Until the first third of the twentieth century, digital calculators remained essentially mechanical.
