Discussion
Which of the following scheduling objectives should be applied to the following: the system should admit jobs to create a mix that will keep most devices busy
Answer: B
Correct answer: to balance resource utilization
Admitting a mixture of jobs so that processor-bound and input/output-bound work run together keeps both the CPU and the devices busy instead of leaving one idle while the other saturates. That objective is balanced resource utilisation; fairness, priority and predictability are separate goals.
