A slot is a narrow opening that serves as a place for receiving or dispensing things. It can also refer to a position or sequence in a series, such as a job opening or assignment. A slot is also used to improve airflow on an aircraft wing. In the U.S., slot receivers are common on the NFL roster.

A slot is a relatively low-traffic area that is also one of the most popular scoring areas in hockey. Because the slot provides an unobstructed view of the net, it allows for more accurate placement of the puck and more precise scoring. In ice hockey, the slot is also a popular place for the wrist shot because of its low location. Slots are often defended by defenders who lay big hits on wingers.

Computers originally had a slot for connecting the processor to the motherboard. This made it easier to upgrade the processor. The first slot was introduced by the Intel Corporation in 1997. In 1999, AMD released the Slot A, which is a similar-looking device but not compatible with Intel Slot 1. In 2000, Intel introduced a larger slot that was used for Pentium II processors. However, slot processors are not commonly found in new computers anymore. Instead, sockets are replacing them.

Slot machines are a highly profitable option for casinos. The payback percentage is usually higher than 75 percent. However, casinos do not want to have a slot machine that is too tight. This is because the odds are built into the computer chip program. If the payback percentage falls below this level, the casino wins.
