In computing, a slot describes an operation issue and data path machinery surrounding a set of one or more execution units.

A slot is a time and place that has been authorized by the airport or air-traffic authority for an aircraft to take off or land. The allocation of these slots is a complex process that involves many variables and can be affected by weather conditions, the type of aircraft and other factors. There are also a number of constraints that affect the availability of slots, and airlines must be aware of these when planning their operations. This is especially true in congested airports, where the number of available slots may be limited. In such cases, airlines must be able to offer alternate routes or schedules that are less congested. Airline capacity is also impacted by the number of available landing and takeoff slots, which is a constraint that must be taken into account when developing an air-traffic management system. The term is sometimes used to refer to a position or berth on an aircraft, but this usage is not considered standard and should be avoided.
