(1.) The action of transferring instructions, data, or both between real storage and external page storage. (2.) Moving data between memory and a mass storage device as the data is needed.
A process of taking small sections of rarely used memory and putting them on disk to make room for other small pieces of processes. Similar to swapping, but finer-grained. Paging occurs automatically when memory is in short supply.
(n.) The process of replacing the contents of a page frame with different pages. A page is a fixed-sized unit of memory. See also page frame.
The separation of a program and data into fixed blocks, often 1000 words, so that transfers between disk and memory can take place in page units rather than as entire programs.
Transferring data from main memory to disk as part of the virtual memory subsystem.
A mechanism by which a process can occupy less physical memory than is allocated in the logical address space. Performed through the division of memory into pages that can be paged in from or out to the swap area on disk.
(IEEE) A storage allocation technique in which programs or data are divided into fixed length blocks called pages, main storage/memory is divided into blocks of the same length called page frames, and pages are stored in page frames, not necessarily contiguously or in logical order, and pages are transferred between main and auxiliary storage as needed.
A method of store management which normally allows virtual memory systems.
The process of moving a page of memory to or from disk.
An operating system function used to copy virtual memory between physical memory and the paging file ( see virtual memory). Paging is used when the amount of virtual memory in use has exceeded the amount of physical memory available. Paging is an expensive task in terms of performance and should be avoided if possible.
A page is a logical block of memory. A paged memory system uses a page address and a displacement address to refer to a specific memory location.
The movement of individual pages (4,096 bytes each) between real storage and auxiliary storage (the page data sets) or expanded storage because there is insufficient real memory to hold all the pages needed. The CPU can only execute instructions and operate on data in real memory. Without enough real memory, the operating system writes old pages to disk and reads new pages from disk so that needed data and instructions are in memory.
Technique of swapping items between memory and storage. 8.10
Transfer of pages between main memory and secondary memory.
The process of moving virtual memory back and forth between physical memory and the disk. Paging occurs when physical memory limitations are reached and only occurs for data that is not already "backed" by disk space. For example, file data is not paged out because it already has allocated disk space within a file system. See also virtual memory.
A technique for increasing the memory space available by moving infrequently-used parts of a program's working memory from main memory to a secondary storage medium, usually a disk. The unit of transfer is called a page.
The act of moving pages of memory from RAM to virtual memory on a hard drive. Excessive paging is caused by a lack of actual system memory. In this case...
The I/O necessary to read and write to and from the paging disks: real (not virtual) memory is needed to process data. With insufficient real memory, the operating system writes old pages to disk, and reads new pages from disk, so that the required data and instructions are in real memory.
A method in which an operating system low on free memory swaps idle data and programs to disc into a special file called a swap file. When the data or program is needed again, something else is swapped so allow the data or program back into memory. See also Operating System, Memory, Data, Programs, Disc and File.
A method of managing virtual memory. When a requested page is not found in main memory, an interrupt occurs. The paging device machine then transfers the requested inactive page to memory. High rates of page swapping can degrade performance.
The process by which pages that are allocated to processes and the UBC are reclaimed for reuse.
The process of moving a single memory block from main memory to disk (swap space) to make space available to load more data into memory. Also see Swapping.
In computer operating systems, paging memory allocation algorithms divide computer memory into small partitions, and allocate memory using a page as the smallest building block.
