The boundary where the serve is made in beach volleyball, standard volleyball, and most other variations of the sport is the back line that runs parallel to the net and separates the serving team's court from the opponent's court.

In beach volleyball, the net is set at a height of 2.43 meters (7 feet 11 5/8 inches) for men and 2.24 meters (7 feet 4 1/8 inches) for women. The net divides the two sides of the court and is used as a barrier for blocking the opposing team's shots.

A spike in volleyball refers to a powerful offensive shot where a player jumps and forcefully directs the ball towards the opponent's side of the court. This attack is usually executed near the net and aims to score a point by making the ball land in the opponent's court or creating a difficult return for the opposing team.

Setting in volleyball refers to the technique of using fingertips to direct the ball to a teammate for an attack. The setter usually positions themselves near the net and sets the ball with precise control to facilitate a spike or other offensive plays.

An overhand serve in volleyball is a serve where the server throws the ball up with one hand and strikes it with the other hand in an overhand motion. This type of serve allows the server to generate power and spin on the ball, making it harder for the receiving team to pass or control the ball.

Passing in volleyball refers to the act of receiving the opponent's serve, spikes, or any other attack and directing the ball to the setter. Good passing is crucial for setting up an effective attack and maintaining control of the game.

An ace in volleyball occurs when the server serves the ball in such a way that the receiving team fails to make a valid play, resulting in an immediate point for the serving team. This can happen if the ball is not properly passed or if it lands untouched on the receiver's side of the court.

An underhand serve in volleyball is a serve where the server holds the ball in one hand and swings the other hand in an underhand motion to strike the ball over the net. This serve is typically used when the player wants to achieve better accuracy and control rather than generating power.

The end line in volleyball marks the boundary of the court at the back of each team's side. It is used to determine if a ball has landed in or out of bounds when played during a rally.
