Every input device attached to the motherboard bus lines has a direct line of communication with the CPU. These lines are known as interrupt request lines (IRQs) which can be prioritised. By signalling the CPU that an input is pending, the CPU can alert the operating system to deal with the request, which will then be prioritised accordingly.
