What are the rules and specifics of the volleyball point system?

In volleyball, teams earn points by successfully hitting the ball over the net and landing it in the opponent's court. A point is scored when the opposing team fails to return the ball or commits a fault. The first team to reach 25 points (and be ahead by at least 2 points) wins a set, and matches are typically best of 5 sets. Each team is allowed 3 hits to return the ball, and players rotate positions after each point.
