A player stands behind the inline and serves the ball, in an attempt to drive it into the opponent's court. The main objective is to make it land inside the court and make an ace.
The attack (or spike) is usually the third contact a team makes with the ball. The object of attacking is to handle the ball so that it lands on the opponent's court and cannot be defended.
Block in volleyball
Blocking refers to the actions taken by players standing at the net to stop an opponent's attack.
Pass (or reception) is the attempt by a team to properly handle the opponent's serve, or any form of attack. Proper handling means that the ball reach the position where the setter is standing.
Digging is the ability to prevent the ball from touching one's court after a spike or attack, particularly a ball that is nearly touching the ground.
