TD (Technical Decision) - this occurs when a fight is stopped due to an accidental injury, such as an accidental headbutt, and cannot continue. If enough rounds have been completed (usually more than half), the judges' scorecards are used to determine the winner.

Knockout (KO) - a boxer wins if their opponent cannot get up from the ring within 10 seconds after a punch. This is considered the most decisive form of victory.
