A slot is a position in a computer’s operating system in which data can be stored. In a Windows machine, this is usually in the form of a directory or folder containing files and subdirectories. A slot is also a type of memory location in which data is temporarily stored between operations. Unlike RAM, which is volatile, the data stored in a slot remains intact between power cycles. For this reason, slots are commonly used in disk drives and other peripheral devices.

The history of the slot machine begins with Charles Fey’s 1887 invention of a device that paid out winnings automatically, a major improvement over the earlier Sittman and Pitt machines.
