Answer: (i) pages

Explanation:

  • Virtual memory - Programs (logical address space) are divided into fixed-size blocks called pages.
  • Physical memory is divided into same-size blocks called frames/page frames.
  • Page table maps virtual page number → physical frame number for address translation via MMU.
  • Segments are variable-size logical divisions (segmentation), while blocks is generic; for pure paging the division is pages.

Hence programs are divided into pages, physical memory into frames.
