GO Classes 2023 | IIITH Mock Test 1 | Question: 29
Consider a system with $\mathrm{N}$ bytes of physical RAM, and $\mathrm{M}$ bytes of virtual address space per process. Pages and frames are $\text{K}$ bytes in size. Every page table entry is $\mathrm{P}$ bytes in size, accounting for the extra flags ... $\mathrm{M} / \mathrm{K} \ast \mathrm{P}$ $\mathrm{N} / \mathrm{P} \ast \mathrm{~K}$

Applied test series
We know that the paging scheme suffers from internal fragmentation. S1 : If the CPU attempts to access the unused portion of the last page, the valid/invalid bits will block such accesses. S2 : A possible solution to handle the internal fragmentation issue is to use multiple page sizes. can anyone plz explain me this ? we have to select from s1 and s2 which is correct

Madeeasy workbook, chapter: Memory management
Consider a k-level paging system along with a TLB. A TLB takes 10ns, and a memory takes 100ns on average. The hit ratio of TLB is equal to 0.8. If it is known that the average memory access time is 70ns, then the value of k is?

OS Memory management
Suppose your computer has 512MB of memory. The loaded size of the operating system is 128MB. Now you have 100 programs to run and each of them would take 128MB memory. With an average 70% of I/O wait, what is the current CPU utilization? Minimum, how many of 512MB blocks of memory will you add to your computer to have the CPU utilization just exceeding 98%?
