A slot is a narrow opening. It may be used to receive a signal or to control a machine or machine component.

Slots can be used for receiving signals, but only when the signal is defined to be virtual. If the signal is emitted by an arbitrary class, it can cause a private slot to be invoked in an unrelated class. This is done by marshalling parameters.

Some software developers use time slots or slot scheduling to set deadlines for tasks. They might also use slots to organize meetings or presentations with managers or teams.

Slot based schedules can help improve team productivity, engagement and communication. They can also be helpful in planning, tracking and prioritizing work. These systems can be used to set deadlines and priorities, allocate resources and tools, and plan for work later.

For example, a financial consultant might set deadlines for appointments, book appointments with software and send messages about schedule changes. By establishing important deadlines, slot-based schedules can ensure team members are on track to meet goals.

Slot-based scheduling can also be useful in health care and education. Staff are able to better understand their workloads, plan for future work and keep track of positive and negative outcomes. Slot-based scheduling is used in many companies. In addition, it can help staff be more organized and efficient, and improve overall workflow.

In sports, the high slot, or air gap, is the area in the offensive zone between face-off circles. The winger can put his stick out in front of the goaltender to redirect a shot.
