(d) empty, lot

This question was posed to me in an online interview.

I'd like to ask this question from Process Scheduling Queues in division Processes of Operating System

Answer 1

Correct option is (c) empty, little

For explanation: If all processes are I/O bound, the ready queue will almost empty and the short-term scheduler will have a little to do. I/O bound processes spend more time doing I/O than computation.
