Question
O Consider a system using demand paging
architecture where it takes 6 ms to service the
page fault if either empty frame is available or
replaced page is not to be modified. It takes 15
ms if the replaced page is modified. Assuming
the main memory access time = 1 ms and 70%
of time page to be replaced is modified. The
maximum acceptable page fault rate to get EMAT
(effective memory access time) not more than
3 ms is
% (upto 2 decimal places).
