Detailed explanation-1: -1. Page number(p): This is the number of bits that represent the pages in Logical Address Space or Page number. 2. Page offset(d): This is the number of bits that represent a particular word in a page or the page size of Logical Address Space or page offset.
Detailed explanation-2: -The most significant bits of the virtual or physical address specify the virtual or physical page number. The least significant bits specify the word within the page and are called the page offset.
Detailed explanation-3: -With Paging, Physical memory is broken into fixed-sized blocks called frames. Logical memory is also broken into blocks of the same size called pages. When a process is to be executed, its pages are loaded into any available memory frames from the backing store.
Detailed explanation-4: -The page table contains the base address of each page in physical memory. The base address combined with the page offset defines the physical memory address. The page number is used as an index into a page table. Page table is kept in main memory and a page table base register (PTBR) points to the page table.
