A net ball is on any shot that it goes in the net. A let ball is when you are serving and it hits the net but the ball goes in therefore re-serving.
A serve is used to get points. Like when someone gets a point that team gets to serve. You can served up to as many points as it takes to get up to 25. Anyone can serve depending on the rotation. *Yes, a serve is a technique of getting points. But, its used to get the ball over the net after a rotation. The server continues serving until their team loses the ball then it goes to the opponent's team and their server serves until they lose the ball, and the cycle contiues until the game ends.
