The minimum number of page frames that must be allocated to a running process in a virtual memory environment is determined by
(A) the instruction set architecture
(B) page size
(C) physical memory size
(D) number of processes in memory
There are two important tasks in virtual memory management: a page-replacement strategy and a frame-allocation strategy. Frame allocation strategy says gives the idea of minimum number of frames which should be allocated. The absolute minimum number of frames that a process must be allocated is dependent on system architecture, and corresponds to the number of pages that could be touched by a single (machine) instruction.
So, it is instruction set architecture i.e. option (A) is correct answer.
