Number of entries in the first-level page table for a 32-bit CPU with a 2-level page table system
Hierarchical paging can offer more efficient memory management by organizing the page table in a hierarchical structure, reducing the memory overhead compared to a single-level page table. It allows for better utilization of memory resources by only mapping the necessary page table entries in the page table, which helps in reducing the total number of page table entries needed. Additionally, hierarchical paging can improve the speed of address translation by enabling faster access to the necessary page table entries.
If the page size is 8kb, then 14 bits of the virtual address are used for the final offset. That leaves (48-14) or 34 bits to select the page table entry. That is 17,179,869,184 entries in a maximally filled page table. The physical address size has no bearing to this particular question, because you asked how many entries, not how large the page table would be.
To calculate the page table size, divide virtual address space by page size and multiply by page table entry size. Example: for a 120MB address space with a 4KB page size, you require 30,720 page table entries. If a page table entry is 4 bytes, you require a total page table size of 122,880 or 120KB.
A multi-level page table structure improves memory management efficiency in operating systems by reducing the amount of memory needed to store page table entries. This is achieved by organizing the page table into multiple levels, allowing for more efficient use of memory and faster access to specific memory locations.

Entries on a works cited page should be left-aligned. This means the text should be aligned along the left margin, creating a straight edge on the left side of the page.
Yes, entries on a works cited page are typically not numbered. The entries are arranged in alphabetical order by the author's last name or by the title if there is no author.
No, Works Cited entries should only list page numbers if you are directly quoting, paraphrasing, or referring to specific pages within a source. If the source is a whole book or webpage, page numbers are not necessary.
when the job is scheduled for execution,initially the first page is loaded into physical memory. All other pages of the job are loaded as and when demanded.Hence it is refereed to as Demand Paging Memory Management.The operating system loads this page from the secondary storage and adjusts the page map table entries accordingly.
