The actual interrupting of an event by an interrupt signal is called an __ Select one: a. Interrupt request (IRQ) b. None of the above c. Change request (CRQ) d. Temporal request Change (TRQ)

The correct answer is a. Interrupt request (IRQ).<br /><br />An interrupt request (IRQ) is a signal sent to the processor by a device or a program, indicating that an event has occurred that requires immediate attention. When an interrupt occurs, the processor temporarily stops executing the current task and switches to a special interrupt service routine (ISR) to handle the event. After the ISR is completed, the processor resumes executing the original task.<br /><br />In the context of the question, the actual interrupting of an event by an interrupt signal is called an interrupt request (IRQ).
