Answer #1

If the memory is byte addressable.

Total frames available with 16mb physical memory =physical memory /frame size(which is equal to page size).

=224/219

=25=32. So totally 32 frames are available, in worst case, all the frames will be occupied by process B. Which means 32 pages are the almost size of process B.

So page table at most contains 32 entries.

--------------So given statement is "false" - - - - - - - - - - -
