Tennis is a sport that is played by two or four players and is known for its fast-paced, high-intensity action. 


The objective of the game is to hit a small, lightweight ball over a net and into the opponent's side of the court. 


Points are scored when the opponent is unable to return the ball, or returns it out of bounds. 


The player or team who wins the most points in a match wins the game.


Tennis has its origins in 12th century France, where it was played by monks using their hands. 


The modern version of the sport, which uses rackets to hit the ball, was developed in the late 19th century and has since become one of the most popular sports in the world.


The standard tennis court is 78 feet long and 27 feet wide for singles and 36 feet wide for doubles. 


The net is 3 feet 6 inches high at the center and is stretched across the court. 


The ball used in tennis is made of rubber and is approximately 2.5 inches in diameter.


Tennis is governed by the International Tennis Federation (ITF), which oversees the rules and regulations of the sport and organizes international competitions such as the Davis Cup, the Fed Cup and the four Grand Slam tournaments, which are considered the most prestigious events in tennis: the Australian Open, the French Open, Wimbledon and the US Open.


Tennis players use a variety of shots to play the game, including serves, groundstrokes, volleys, and overheads. 


The serve is the first shot of each point and is used to start the point.


 Groundstrokes are shots that are hit after the ball bounces on the ground, while volleys are shots that are hit before the ball bounces on the ground. 


Overheads are shots that are hit when the ball is above the player's head.


The professional tennis circuit includes the ATP Tour (Association of Tennis Professionals) for men and the WTA Tour (Women's Tennis Association) for women. 


These tours consist of a series of tournaments held throughout the year, with the top players competing in the Grand Slam tournaments and the Masters tournaments.
