What is a side out in volleyball?

In volleyball, a side out refers to the team that wins the rally and earns the right to serve the ball. When a team sides out, they score a point and the serve rotates to the opposing team. Side outs are part of the scoring system in volleyball, with each rally resulting in a point being scored for one of the teams. The first team to reach a set number of points (usually 25) wins the set.
