2. Define feedback.
Answers
Answer: The observation of the receiver’s response is called feedback.But in Computer science Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself .
Explanation:
If we were to use a heating system, we could deduce how feedback is used. A sensor detects the temperature. When the temperature reaches a certain threshold, a signal will be sent to an actuator which will trigger the heating to turn on and start heating the area where the temperature sensor is located.
Negative feedback
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
Positive feedback
Positive feedback is a process that occurs in a feedback loop in which the effects of a small disturbance on a system include an increase in the magnitude of the perturbation.
Answer:
response of the sender information is called feedback
