Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through the defender's hoop while preventing the opposing team from shooting through their own hoop. Games are played in four quarters of 10 minutes (FIBA). 15 minutes are allowed for a half-time break under FIBA rules. At the beginning of the match, a ball is thrown, and then at the beginning of each quarter, the ball is given to each team in a row. Teams exchange baskets for the second half. Each time a basketball rule is violated, the player is injured or has technical problems, the time is stopped. Time is restarted when another player catches the ball from behind the rear line.
