Which term refers to the board inside a slot machine that handles interface functions?

• A. Slot Machine
• B. Slot Accounting System (SAS)
• C. Slot Machine Interface Board (SMIB)
• D. Site Controller

Answer: (C)

The main idea is recognizing the internal hardware responsible for connecting a slot machine’s components to its control system and to external networks. The term Slot Machine Interface Board, abbreviated SMIB, is used to describe that board because its job is to handle interface functions—meeting timing, routing signals, and coordinating data between the machine’s I/O (like coin validators, buttons, displays, printers, sensors) and the machine’s control logic or host systems. The other options point to broader or different systems: the Slot Machine is the entire device, not a specific board; the Slot Accounting System tracks play and payouts for accounting purposes; and the Site Controller oversees operations across multiple machines at a location. So SMIB is the precise inside-the-machine component that handles interface functions.
