Q. Presume that a scheduling algorithm at the level of short-term CPU scheduling favours those processes that have used the least processor time in the recent past. Why this algorithm favour I/O-bound programs and yet not permanently starves CPU-bound programs?
Answer: It will favour the I/O-bound programs for the reason that of the relatively short CPU burst request by them however the CPU-bound programs will not starve for the reason that the I/O-bound programs will relinquish the CPU relatively often to do their I/O.
