Explain technical foul and multiple foul.

Technical foul: a non-contact foul by a player (such as unsporting behaviour, arguing with the officials or delaying the game) or by a coach, substitute or team follower. Penalty: one free throw to the opponents, followed by a throw-in from the centre line. Multiple foul: a situation in which two or more teammates commit personal fouls against the same opponent at about the same time. Penalty: each offender is charged with a personal foul, and the free throws are awarded for one foul only.
