What Ken said in great detail, but to provide a more simple explanation, the knock sensor system will prevent you from melting or shattering the pistons in their respective cylinders when temperatures get too high.

I ran a boosted 4 cylinder engine beyond its limits on low octane gas. When I removed what was left of the pistons after the engine died, the pistons looked like molten tennis balls, and yes, I heard the "detonation" but ignored it. My bad.
