Theres a sticky right here on this forum that does a great job explaining it.

If your discouraged from reading the long post i will give a brief description. As already mentioned it is knock retard or detonation. The engine creates a controlled explosion which creates power [hence internal combustion engine]. Knock is when the explosion is uncontrolled often because of heat.

It's important to understand that KR is not detonation. It is the PCM's response to detonation to keep your engine in one piece.
