Basketball is a five-a-side team sport in which two teams try to score by shooting a ball through an elevated hoop on the opponents' end of the court, with the team accumulating the most points winning the game. Invented in 1891 and now played worldwide, it combines fast movement, precise shooting and constant transitions between attack and defence, and is governed internationally by FIBA and professionally in North America by the NBA.
Its blend of speed, skill and frequent scoring has made it one of the most popular indoor and outdoor sports in the world.
What Basketball Is and How It Is Played
Each team has five players on the court at a time. The objective is to advance the ball toward the opponents' basket and shoot it through the hoop, which sits 3.05 metres above the floor. Players move the ball by dribbling, bouncing it with one hand while moving, or by passing it between teammates. Running while holding the ball without dribbling is a travelling violation and turns the ball over to the other team.
Play flows continuously, with possession switching rapidly after made baskets, rebounds and turnovers. Unlike sports built around set restarts, basketball rewards quick decision-making in transition and constant repositioning, a quality it shares with fast team games such as handball.
Core Rules and Violations
Several timing and ball-handling rules keep the game moving. A team must attempt a shot within the shot clock period, advance the ball past the halfway line within a set time, and avoid lingering too long in the restricted area near the basket.
- Travelling: moving the feet illegally while holding the ball.
- Double dribble: dribbling, stopping, then dribbling again, or dribbling with two hands.
- Shot clock violation: failing to attempt a shot within the allotted time.
- Backcourt violation: returning the ball to the team's own half after advancing it.
Physical contact is restricted. A personal foul is called for illegal contact such as pushing, holding or hitting; a player who accumulates a set number of fouls is disqualified from the game. Repeated team fouls put the opposition in the bonus, awarding free throws.
Scoring
Points are awarded based on where a shot is taken. A basket made from inside the three-point arc is worth two points, while a successful shot from beyond the arc is worth three. A free throw, an unguarded shot taken from the free-throw line after certain fouls, is worth one point.
The team with the most points when time expires wins. If the score is tied at the end of regulation, the game continues in overtime periods until one team leads at the end of a period. Frequent scoring is a defining feature, with competitive games often reaching scores well above one hundred points.
Equipment and the Court
The essential equipment is an inflated ball and two baskets, each consisting of a hoop with a net mounted on a backboard. Players wear a jersey, shorts and supportive footwear designed for quick lateral movement and jumping. The court is a rectangular hard surface, 28 metres long and 15 metres wide under international rules.
Key court markings include the centre circle, the three-point arc surrounding each basket, the free-throw line and the restricted area beneath each hoop. The rim sits 3.05 metres above the floor at both ends, a height that has remained constant since the game's early years.
History and Origins
Basketball was invented in December 1891 by James Naismith, a physical education instructor in Springfield, Massachusetts, who sought an indoor game to keep students active during winter. The first version used a soccer ball and two peach baskets nailed to a railing, with thirteen original rules.
The sport grew quickly through schools and colleges, became an Olympic event for men in 1936, and developed professional leagues over the twentieth century. FIBA governs the international game, and the women's game has likewise grown into a major worldwide competition.
Positions, Competitions and Skills
Traditional positions are the point guard, shooting guard, small forward, power forward and centre, each balancing ball-handling, shooting and rebounding responsibilities. Major competitions include the NBA, the FIBA Basketball World Cup and the Olympic tournament.
Core skills are shooting accuracy, dribbling control, passing vision, rebounding and defensive footwork. Athleticism matters, but so does court awareness: reading the defence, spacing the floor and making fast decisions under pressure are what separate strong players from the rest.
