The term feedback is from 1920, in the electronics sense, "the return of a fraction of an output signal to the input of an earlier stage." "Information about the results of a process" is attested by 1955.
Feedback comes in many forms. There is structured and unstructured feedback. There can also be no feedback, negative feedback, positive feedback, and appreciative feedback. Feedback is a gift. Please give feedback so we can improve.
