Suppose you have a computer system with a $48-bit$ logical address, page size of $16KB$ and $4 bytes$ per page table entry. If we have a $48MB$ program such that the entire program and all necessary page tables are in memory. How much memory is used by program, including its page tables?

No of pages = (process size) / (page size)

                     = (48 MB) / (16 KB)

                      = 3K

Page Table Size = (no of pages) * page table entry

                          = (3K) * (4B)

                          = 12 KB

Total memory used by the program = (process size) +  (page table size)

                                                         = (48 MB) + (12 KB)

                                                         = 49164 KB

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?
