Which of the following statements are true? Select all that apply
Select 3 correct answer(s)
Interrupt handling is carried out in kernel mode
The appropriate interrupt service routine to be called is found through the
interrupt vector table
Hardware interrupts are always predictable. The kernel is able to predict harware
interrupts in advance
The source of an interrupt is identified based on a source identifier supplied with
the interrupt request by the hardware
