Virtual addresses are used by the accessing process, while physical addresses are used by the hardware or more specifically to the RAM. == Role of the page table == In operating systems that use virtual memory, every process is given the impression that it is working with large, contiguous sections of memory. In actuality, each process' memory may be dispersed across different areas of physical memory, or may have been moved (paged out) to another storage, typically to a hard disk. When a process requests access to a data in its memory, it is the responsibility of the operating system to map the virtual address provided by the process to the physical address of the actual memory where that data is stored. The page table is where the operating system stores its mappings of virtual addresses to physical addresses, with each mapping also known as a ''page table entry'' (PTE).〔(【引用サイトリンク】title=Virtual Memory )〕〔(【引用サイトリンク】title=Page Table Management )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Page table」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
