Originally, the term “slot” referred to a small hole in the face of a typewriter key, which was used to hold the typebars when they were not in use. It later came to mean a small gap or pocket in the face of a typewheel, which held the carriage return lever and the slug bar when it was not in use. A slot could also refer to the slug bar itself, which was a metal rod that was inserted into the slit in the typewheel to control its movement.
When a player inserts cash or, in the case of ticket-in, ticket-out machines, a paper ticket with a barcode into the slot machine, the machine activates the reels and displays symbols based on its paytable.

Most slot games have a theme, and the symbols and other bonus features are aligned with this theme.

It also contains the kernel’s security features, which help protect the kernel and other core modules from exploits.
