+<br>In computer working methods, memory paging is a [Memory Wave Experience](http://p029.bluew.net/bbs/board.php?bo_table=note&wr_id=351486) administration scheme that allows the physical memory utilized by a program to be non-contiguous. This additionally helps avoid the issue of memory fragmentation and requiring compaction to cut back fragmentation. For historical reasons, this method is typically referred to as swapping. When combined with virtual memory, it is known as paged virtual memory. In this scheme, the working system retrieves knowledge from secondary storage in blocks of the same dimension (pages). Paging is a vital a part of virtual memory implementations in modern operating methods,  [Memory Wave](https://english4u.com.br/2025/08/13/memory-wave-the-ultimate-brainwave-entrainment-for-cognitive-enhancement-7/) utilizing secondary storage to let programs exceed the scale of accessible physical memory. Hardware help is necessary for environment friendly translation of logical addresses to physical addresses. As such, paged memory performance is often hardwired into a CPU via its Memory Management Unit (MMU) or Memory Protection Unit (MPU), and separately enabled by privileged system code within the operating system's kernel.<br>

+<br>In CPUs implementing the x86 instruction set structure (ISA) for instance, the memory paging is enabled via the CR0 control register. In the 1960s, swapping was an early [digital memory](https://www.huffpost.com/search?keywords=digital%20memory) method. An entire program or whole section can be "swapped out" (or "rolled out") from RAM to disk or drum, and one other one can be swapped in (or rolled in). A swapped-out program can be current however its execution can be suspended whereas its RAM was in use by one other program
