Used for address translation
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.

The table table of contents
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.

The table of contents page is located at the beginning of the book. This page usually outlines each chapter of the book.
The valid bit in a page table indicates whether a page is currently in use or not. It impacts the functionality of the page table system by helping the operating system efficiently manage memory. When a valid bit is set, it means the page is in use and can be accessed by the CPU. If the valid bit is not set, it indicates that the page is not currently in memory and the operating system needs to retrieve it from secondary storage. This helps prevent unnecessary memory accesses and improves system performance.
