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?
🎥 Video solution / Text Solution of this question is given below:
(4) — Interrupt-driven I/O frees the CPU for compute-heavy jobs; under very I/O-intensive loads, polling (programmed I/O) can outperform by avoiding high interrupt overhead.
