Basketball is a sport played by two teams of five players on a court. The objective is to shoot the ball through a hoop by passing and dribbling. It was invented in 1891 by Dr. James Naismith in Springfield, Massachusetts. Players position themselves on the court in roles like point guard, center, or power forward. Shooting methods include jump shots, layups, and slam dunks. Teams advance by passing, dribbling, rebounding missed shots, and blocking opponents' shots all while following the rules enforced by referees.
