The purpose of feedback from input and output is to facilitate evaluation and improvement within a system. By assessing the relationship between inputs (resources or data) and outputs (results or products), feedback helps identify areas for enhancement, optimize processes, and ensure that objectives are being met. This iterative process is essential for continuous learning and adaptation, allowing systems to respond effectively to changes and improve overall performance.
A circuit in which output feeding back to input to increase or decrease the gain is called feedback circuit. Basically part of output feeding to input in such way that it increase the value of input is positive feedback and it also increase gain of circuit and similarly to it when part of output feeding to input in such way that it decrease the value of input is called negative feedback it also decrease the gain of circuit.
In a positive feedback system, the output enhances or amplifies the input that started the process, causing a self-reinforcing loop. This means that an increase in the output leads to an increase in the input, continuing to drive the system further in the same direction.
A joystick is an input to a computer. A tiny caveat is that some joysticks have feedback - so they can vibrate to simulate resistance or movement; the feedback is an output.
A: To feedback more of the same signal from the output to increase the input to farther increase the output and farther increase the input will ultimately saturate the system

output resistance decreases and input resistance increases
The current series feedback is a negative feedback in which the output current feeds back a proportional voltage back to the input terminals in series with the input signal. Here the output impedance as well as the input impedance increases as both are connected in series.
Output is obtained for a given input and we cant control the output my means of any feedback loop control to the input
output is feedback in input

Input, Processing, Output and Feedback
Input is often referred to as "data entry," "information input," or "user input," while output is commonly called "data output," "results," or "information output." In computing contexts, input can also be termed "feed" or "source data," and output might be described as "display," "results set," or "feedback."
