Answer:By disabling the virtual memory system,processes are guar-anteed to have portions of its address space resident in physical mem-ory.This results in a system that does not suffer from page faults and therefore does not have to deal with unanticipated costs correspond-ing to paging the address space.The resulting system is appealing todesigners of real-time systems who prefer to avoid variability in per- formance.
