Main article: Paging
A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in a page table. It is the smallest unit of data for memory management in an operating system that uses virtual memory. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system.[1][2][3]
A transfer of pages between main memory and an auxiliary store, such as a hard disk drive, is referred to as paging or swapping.[4]
