$(10$pt$)$ Consider the demand paging, the normal memory access time $=200$ nanoseconds, and the average

page$-$fault service time $=4$ milliseconds. Given page fault rate $P,$ effective access time EAT $=(1-p)*$

memory access time $+p*$page$-$fault service time.

$(5$pt$)1)$ If one access out of $3,000$ causes a page fault, calculate the effective access time.

$(5$pt$)2)$ If we want the performance degradation In how many page accesses do we allow one page

fault?
