A slot is a narrow opening, groove, or notch that fits a printed circuit board. They are very useful in electronics because they can store data or pass values from one component to another. They are also useful in air traffic management, since slots keep airplanes from repeatedly crashing into each other.
The word slot is derived from the Latin verb sleutana, which means “slave of technology.” It is cognate with the German Schloss. The term is also used in ice hockey to refer to the fourth position of the flying display, which is often referred to as the scoring area.

A slot function accepts a fixed name, which can be a string or expression, and then evaluates an expression to return information about individual slots in an object or class. The expression must be a valid class definition, and it must be quoted if it contains any letters or numbers.

In the SMBIOS information structure, there are three classes that define slots. The Slot Characteristics class defines how the slot device is used, the System Slots class describes how to use the slot in an application, and the CIM_PhysicalElement class describes the physical structure of the slot.
It is also possible to create a slot type from an existing object. For example, a slot can be created from a table or from a tuple.
When you create a slot, you can specify the location of the slot by providing the slot’s name and a connection parameter. This information is then passed to the slot function to determine how it should interact with the component that contains it.
