What are "open-loop" and "closed-loop" systems

open loop is by the fact that the output signal or condition is neither measured nor “fed back” for comparison with the input signal or system set point. Closed-loop an automatic control system in which an operation, process, or mechanism is regulated by feedback.

An open-loop system is a control system that has no means for comparing the output (the results of the operation of any system) with input (something put into a system, such as resources, in order to achieve a result) for control purposes.

A closed-loop system is a control system that uses feedback from the output (the results of the operation of any system) to control the input (something put into a system, such as resources, in order to achieve a result).

Explanation: Foundation Of tech

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
