What Is a Slot?


A slot is a narrow opening into which something can be inserted. Slots are found in machines and devices from a variety of industries, including computer motherboards. They can be used for expansion cards or memory modules.

The term is also used for a specific time slot, such as in a schedule or program. A person might book a time slot in advance to ensure they get the desired appointment or activity. The same concept is used in airport coordination, where a slot is an authorization to take off or land at a particular airport during a specific day and time. This limits the number of planes that can operate at a busy airport, and prevents repeated delays caused by too many flights trying to take off or land at the same time.

In football, a slot receiver is a wide receiver who lines up a few yards behind the line of scrimmage and slightly in front of the outside wide receivers. This gives them more routes to run, and allows them to attack all three levels of the defense. In addition, slot receivers are important blockers and can help protect running backs on outside run plays.

When playing a slot machine, it is important to read the pay table before placing your bet. It will provide information on the payouts for different symbols, as well as any jackpot caps a casino may have. Pay tables are usually listed on the machine’s rules or information page, and can also be found by searching the game’s name with keywords such as “payout percentage” or “return to player.” Alternatively, players can ask customer support for assistance.
