What is the difference between an open-loop system and a closed-loop system?

Question

Accepted Answer

Open-loop systems operate without feedback, while closed-loop systems use feedback to adjust and improve performance.

Open-loop systems do not monitor their output; for example, a toaster simply heats bread for a set time.
Closed-loop systems use feedback to adjust their operation; for example, a thermostat regulates temperature by adjusting heating based on current temperature.
Open-loop systems are simpler and often less expensive, but less accurate; closed-loop systems are more complex but provide better control.
Examples of open-loop systems include washing machines and microwave ovens, while examples of closed-loop systems include cruise control in cars and automated manufacturing processes.
