How does 'knocking' damage your car and reduce power and acceleration?

A knock sensor is designed to detect knock, often even before the driver does. Upon sensing knocking or pinging, the engine's computer control system adjusts the engine's operation by retarding the spark timing to avoid the knock. These adjustments can reduce power and acceleration, particularly during heavy throttle, just when you need power the most!
