In a virtual memory environment
Virtual memory is an integral part of a modern computer architecture; implementations usually require hardware support, typically in the form of a memory management unit built into the CPU. While not necessary, emulators and virtual machines can employ hardware support to increase performance … See more In computing, virtual memory, or virtual storage is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the … See more In the 1950s, all larger programs had to contain logic for managing primary and secondary storage, such as overlaying. Virtual memory was … See more Some systems, such as the Burroughs B5500, use segmentation instead of paging, dividing virtual address spaces into variable-length segments. A virtual address here consists of a segment number and an offset within the segment. The See more • Processor design • Page (computer memory) • Cache replacement policies • Memory management See more Virtual memory makes application programming easier by hiding fragmentation of physical memory; by delegating to the … See more Nearly all current implementations of virtual memory divide a virtual address space into pages, blocks of contiguous virtual memory addresses. Pages on contemporary systems are usually at least 4 kilobytes in size; systems with large virtual address … See more Some operating systems provide for swapping entire address spaces, in addition to whatever facilities they have for paging and segmentation.
