WebMay 12, 2024 · The page size on the x86_64 architecture (same as in i386 or IA-32, which is the 32-bit version of the architecture) is 4KiB. You will also see references to 2MiB because that's one of the sizes of "huge pages" in the x86_64 architecture, which also allows for 1GiB huge pages, which are used in Linux in some situations as well. Web1 The frame size is 2KB. Assuming memory is byte-addressable, we need an offset into 2000 different bytes. 2000 is approximately (2^10)*2 = 2^11, so we need 11 bits for the frame offset. Then, we can easily calculate that 33 - 11 = 22 bits are used to identify a physical page (frame), and 34 - 11 = 23 bits are needed to identify a virtual page.

Page Offset consisting of 10 bits. As we page the Page table, the page number is further divided into : Page Number consisting of 12 bits. Page Offset consisting of 10 bits. WebApr 10, 2024 · The standard page size in x86 systems is 4 kB. This is optimal for general purpose computing but larger page sizes - 2 MB and 1 GB - are also available. These larger page sizes are known as huge pages. Huge pages result in less efficient memory usage as a process will not generally use all memory available in each page.
WebA page is made up of unit blocks or groups of blocks. Pages have fixed sizes, usually 2k or 4k, and a fixed-length block of contiguous memory is called a Page. A page is also called a virtual page or memory page. In VM Operating System, it is the data's smallest unit that manages memory with the help of Page OS performs both function reading ...
