Volleyball is a popular sport played by over 800 million people worldwide. The game involves two teams of six players separated by a high net, with the objective being to ground the ball on the opponent's side of the court without letting it touch the ground three times. The typical volleyball court measures 18 by 9 meters and can be played on surfaces like gym floors, sand, or grass. Players rotate in a clockwise direction and must follow serving order until the ball is put into play, with the first team to score 25 points in sets of 2 winning the match.
