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?

Self Doubt | Logical Address | Virtual Address | Virtual Memory
Can anyone explain how are these two things connected (i) Virtual Memory (part of HDD, acting as RAM) and (ii) Virtual Address Space (Logical Address, generated by CPU during compilation), and where exactly is this Logical Address stored?

Multilevel paging
The below question is from made easy test series: Consider a 32 bit virtual address as follows: 10 8 6 8 P1 P2 P3 Offset System uses 3 level paging and the bits for the respective levels are as indicated above. Then the size of page table for a process which requires 256 KB of ... $\frac{2^{8}} {2} $ = 2$^{7}$ pages. I don't know what I am getting wrong. Please correct me.

Operating System: Self Doubt - Memory Management
Considering a system with Single-Level page table, with a TLB to reduce the access time of pages. A cache is also provided with the main memory. All the pages ultimately reside in MM. (assuming there's no page fault). Let, TLB Hit Ratio = x TLB Access ... for TLB miss it will be (a+c+p). But if this is true, why can't we store Page Table in a Cache?

Memory Management
In a virtual memory system, size of the virtual address is 32-bit, size of the physical address is 30-bit, page size is 4 KByte and size of each page table entry is 32-bit. The main memory is word addressable and word size is 4Bytes. Find the maximum number of bits that can be used for storing other information ?
