In operating systems that use virtual memory, every process is given the impression that it is working with large, contiguous sections of memory. In reality, each process' memory may be dispersed across different areas of physical memory, or may have been paged out to a backup storage (typically the hard disk). When a process requests access to its memory, it is the responsibility of the operating system to map the virtual address provided by the process to the physical address where that memory is stored. The page table is where the operating system stores its mappings of virtual addresses to physical addresses.

What value is placed in the page table to redirect linear address 20000000 to physical address 30000000?
subtract 20000000H from 30000000H,because the page table is just a bunch of offsets. So the memory manager would lookup 20000000H in the table, find 10000000H, add'em up and get 30000000H. If that's how it works.

What is the purpose and functionality of an inverted page table in operating systems?
An inverted page table in operating systems is used to map virtual memory addresses to physical memory addresses. It helps in efficiently managing memory by allowing multiple virtual pages to be mapped to a single physical page. This helps in reducing memory overhead and improving performance by avoiding the need for a separate page table for each process.
How page table size calculate when virtual address space and page size and page table entry size given?
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.

Advantages of hierarchical paging?
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.
