What is an "ace" in volleyball terminology?

An "ace" in volleyball terminology refers specifically to a serve that is not touched by the opponent and directly results in a point. This means that the serve lands in the opponent’s court without any interference, indicating that the serve was executed perfectly, making it impossible for the receiving team to play the ball.

The successful execution leading to an immediate point reflects the server's skill in delivering the ball with speed, precision, or strategic placement that catches the opposing team off guard. In competitive play, aces are highly valued as they demonstrate effective serving and can shift the momentum of a match in favor of the serving team.
