GO Classes Test Series 2024 | Mock GATE | Test 13 | Question: 45
Imagine a computer with a $32$-bit virtual address space and $\text{1 KB}$ pages. It uses a two-level page table system, with page-sized chunks at the inner level(not at the outer level). Suppose the code is located at address $0,$ and there are ... is $4$ Bytes.) $64 \mathrm{~KB}$ $2 \mathrm{~KB}$ $66 \mathrm{~KB}$ $16 \mathrm{MB}$

Memory Management
Assume in a computer supporting paging, virtual addresses are 36 bits long. Page size is 16 KB, no matter which paging structure is used. Assume a page table entry is 8 bytes long, no matter which paging structure is used. The computer has 4 GB of RAM (physical ... a) One level page table. b) Two level page table with address division scheme (11, 11, 14). c) Inverted page table.

Made Easy Question : Multilevel Paging system, please refer the question below.
In this question, they have asked for memory requirements for page tables across the levels, solving which I am getting number of level 3 page tables as 2^8. Below is a brief of my approach, can anybody please explain if I am right or ... 3 PTs + level 4 PTs = 1 + 1 + 2^8 + 2^16 Where am I doing wrong? Please explain.

GATE CSE 2023 | Question: 48
Consider a computer system with $57$-bit virtual addressing using multi-level tree-structured page tables with $\mathrm{L}$ levels for virtual to physical address translation. The page size is $4 \mathrm{~KB}(1 \mathrm{~KB}=1024 \mathrm{~B})$ and a page table entry at any of the levels occupies $8$ bytes. The value of $\mathrm{L}$ is ______________.

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.

Andrew S. Tanenbaum (OS) Edition 4 Exercise 3 Question 19 (Page No. 256)
A computer with a $32-bit$ address uses a two-level page table. Virtual addresses are split into a $9-bit$ top-level page table field, an $11-bit$ second-level page table field, and an offset. How large are the pages and how many are there in the address space?

Self Doubt:Paging
I have read that paging does not suffer from external fragmentation as the frames and the pages are all of the equal sizes, but when we store a last level page table in a frame at that time it may not fully occupy the frame. Similarly, if ... exceed a page size. Then there should be external fragmentation, right? So why is it said that paging does not have external fragmentation?

OS-Multi-Level Paging
Consider a computer system using 2-level paging with TLB.The logical address supported is 32 bits. The page table is divided into 512 pages each of size 1KB.Page table entry size at $1^{st}$ level is 2 Bytes and at second level is 4 Bytes each. What is ... of 1 page of second level PT=1KB. So, the total required memory overhead=8+1=9KB. Is my analysis and answer both correct?

Paging
In multi-level paging, a big page table is divided into smaller pages and for those pages (of main page table) a new page table is created. So what be basically did is broke down the main page table into small pieces (usually so to reduce the size of parts to page size). But, the overall size of the main page table remain same, right? Then what actually is the benefit of multilevel paging?
