Marks: +1, -0

Consider a system running under two types of workloads:
(a) CPU-intensive jobs
(b) I/O-intensive jobs Which of the following statements about the relative performance of Interrupt-driven I/O and Programmed I/O is correct?

Interrupt-driven I/O performs better for CPU-intensive jobs by freeing the CPU, while Programmed I/O performs better for I/O-intensive jobs due to tighter control.
Programmed I/O performs better in both CPU-intensive and I/O-intensive workloads because it gives the CPU full control.
Programmed I/O performs better for CPU-intensive jobs, while Interrupt-driven I/O performs better for I/O-intensive jobs.
Interrupt-driven I/O performs better in both CPU-intensive and I/O-intensive workloads because it always reduces CPU involvement.
