Explanation

IRQ stands for Interrupt Request, which is a signal sent to the CPU to get its attention for an event that needs immediate processing. The 'Q' in IRQ is sometimes incorrectly expanded to 'Queue', but the correct expansion is simply 'Interrupt Request' - there is no word starting with Q in the expansion.
