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.
