In virtual memory systems, Dynamic address translation

  • A.is the hardware necessary to implement paging
  • B.stores pages at a specific location on disk
  • C.is useless when swapping is used
  • D.is part of the operating system paging algorithm

Answer: A

Correct answer: is the hardware necessary to implement paging

Dynamic address translation is the hardware - the memory management unit, with its page table and translation lookaside buffer - that converts each virtual address into a physical one as the instruction executes. Without it paging could not work, because every reference would have to be translated in software.
