A feedback mechanism is a process that helps systems maintain balance and stability. It works by using information about the system's current state to make adjustments. For example, in the human body, the nervous system sends signals to regulate temperature. If you get too hot, your body sweats to cool down, demonstrating how feedback helps maintain a stable environment. In technology, feedback mechanisms are also important. For instance, in a thermostat, when the temperature rises above a set point, the device turns on the air conditioning to bring it back down. This continuous loop of monitoring and adjusting ensures that systems function effectively.
