Basketball is a team sport in which two teams of five players each, attempt to best each other at the main objective: to project a ball through a hoop. Basketball was invented by Dr. James Naismith, a Canadian professor of physical education.
The game involves bouncing (dribbling) the basketball and attempting to score by projecting (shooting) the ball through a metal horizontal ring referred to as a basket or a hoop. The game is played on hardwood floor, the dimensions of which may vary. Each team tries to prevent the other from scoring while attempting to gain control of the basketball in hopes of shooting the ball through a basket of their own. Strict rules govern the specifics of gameplay and they may vary slightly between organizations such as FIBA or the NBA. Officials, known as referees, are in charge of enforcing these rules during live play.
