Final answer:
Turning on a TV with a remote control represents an input in a system. An input is the action that starts a process leading to an output. Feedback, on the other hand, is the response the system provides following an output.
Step-by-step explanation:
Turning on a TV with a remote control represents an input in a system. An input is the initial action that triggers a process within any given system. In this case, pressing the power button on the remote sends a signal to the television, which is the input telling the TV to turn on. This is the start of a sequence that leads to the television operating and displaying images and sound, which is the output.
In comparison, the process is the operation the system performs after it receives an input, leading to an output. Feedback, often in the form of confirmation messages or lights, is the system's way of communicating back to the user that an action has been completed or that some form of adjustment is necessary. In the case of the TV, feedback might be the visible change on the screen indicating it has been turned on or an auditory signal.
