A slot is a time period that is allocated for a task. Using a slot-based schedule can help teams prioritize work and stay on track to meet deadlines. This method of scheduling can also reduce confusion about the due date and improve efficiency by avoiding conflicts.

Slot is a term for a slot in a computer motherboard, often used to refer to expansion slots (for instance, ISA, PCI, AGP, or memory slots). The term also can refer to a time slot at an airport, as defined by EUROCONTROL as part of their Air Traffic Management role. Air Traffic Management slots are allocated to airlines at times when an airport is constrained, for example by runway capacity or available parking space. The use of slot-based air traffic management has led to significant savings in delay and fuel burn, as well as improved efficiency and safety.
