Cricket Innings is a term used to describe the two halves of a cricket match. An over is a set of six consecutive deliveries bowled by a single bowler. Each over is divided into two parts, with three balls bowled in each part. The overs are used to measure the length of an innings, which is the period of play during which one team bats and the other team bowls and fields. The number of overs in an innings can vary depending on the format of the game.
