Another solution to the problem of external fragmentation problem is to :

  • A.permit the logical address space of a process to be noncontiguous
  • B.permit smaller processes to be allocated memory at last
  • C.permit larger processes to be allocated memory at last
  • D.all of the mentioned

Answer: A

Correct answer: permit the logical address space of a process to be noncontiguous

If a process need not occupy one unbroken run of memory, it can be fitted into whatever holes exist, and external fragmentation ceases to matter. That is the idea behind paging and segmentation.
