What happens when an interrupt is serviced?
The CPU continues with its current task.
The operating system is shut down.
The contents of the registers are reloaded.
The current task is interrupted, and the interrupt's routine is executed.
Explication
When an interrupt is serviced, the CPU stops its current operation to handle the interrupt request.
