Basically, to serve a tennis ball, you need to toss the ball high enough and in front of you (i.e., toward the net), so that your racquet will make contact with the ball at some point, and so that most of your weight is "behind" the ball, in order to get the most out of the racquet's momentum when it strikes the ball. The server always stands in the half of the court diagonally from his/her opponent's half of the court; the halves are referred to as the "deuce" (right half) and "ad" (left half) sides. At the end of a given point, each player moves to the other half, and the process is repeated until the game is won.
Sports where you serve a ball include tennis, volleyball, badminton, table tennis, and pickleball. In tennis, the serve starts each point, while in volleyball, the serve initiates play and is crucial for scoring. Badminton and table tennis also require a serve to start each rally, and in pickleball, the serve is used to begin each point as well.
In a game of tennis, you serve from behind the baseline on the right side of the court.

You can hit an underhand serve in tennis; however, the overhand serve is more effective because it is more powerful. That is why you don't see the underhand serve used much.
In tennis, you serve the ball from behind the baseline into the diagonally opposite service box on the other side of the net.
