What is Page offset in paging?
Hereof, what is a page offset?
Page offset(d): Number of bits required to represent particular word in a page or page size of Logical Address Space or word number of a page or page offset.
Furthermore, how is paging offset calculated? 2. offset = A mod page_size
- this is the distance from the beginning of the page.
- e.g. address in the process, A = 10,000.
- page size = 4k.
- page offset = 10000 mod 4k = 10,000 mod 4096 = 1908.
- this calculation is done quickly on the computer since the page size is power of 2, e.g., 4k = 2^12.
Then, what is Page offset in virtual memory?
Offset. A page has many bytes of memory inside it, so the last bits of the virtual address are called the offset which is the location difference between the address you want and the start of the page. You require enough bits in the offset to be able to get to any byte in the page.
What means paging?
In computer operating systems, paging is a memory management scheme by which a computer stores and retrieves data from secondary storage for use in main memory. In this scheme, the operating system retrieves data from secondary storage in same-size blocks called pages.
