• Basketball is an indoor sport, in which two teams of five players try to score points by “shooting" a ball through the top of a basketball hoop.
• A team can score a field goal by shooting the ball through the hoop during  play.
• A field goal scores two points for the shooting team if a player is touching or closer to the hoop than the three-point line, and three points if the player is "outside" the three-point line.

Rules and regulations 

• A successful shot is worth two points or three points if it is take beyond the arc which is 6.25 meters, one-point shot can be earned when shooting from the foul line after a foul is made.
• Games are played in four quarters of 10 (FIBA) or 12 minutes (NBA).

Fouls

• Players who are fouled either receive the ball to pass inbounds again, or receive one or more free throws if they are fouled in the act of shooting, depending on whether the shot was successful.
• If a team exceeds a certain limit of team fouls in a given period – four for NBA and international games – the opposing team is awarded one or two free throws on all subsequent non-shooting fouls for that period, the number depending on the league.

Player Positions

• Point guard: usually the fastest player on the team organizes the team's offense by controlling the ball and making sure that it gets to the right player at the right time.
• Shooting Guard: creates a high volume of shots on offense; guards the opponent's best perimeter player on defense.
• Small forward: often primarily responsible for scoring points via cuts to the basket and dribble penetration; on defense seeks rebounds and steals, but sometimes plays more actively.
• Power forward: plays offensively often with their back to the basket; on defense, plays under the basket (in a zone defense) or against the opposing power forward (in man-to-man defense).
• Center: uses height and size to score (on offense), to protect the basket closely (on defense).
