  2. Virtual memory - Wikipedia

    en.wikipedia.org/wiki/Virtual_memory

    Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".

  3. Virtual memory compression - Wikipedia

    en.wikipedia.org/wiki/Virtual_memory_compression

    By reducing the I/O activity caused by paging requests, virtual memory compression can produce overall performance improvements. The degree of performance improvement depends on a variety of factors, including the availability of any compression co-processors, spare bandwidth on the CPU, speed of the I/O channel, speed of the physical memory, and the compressibility of the physical memory ...

  4. Physical Address Extension - Wikipedia

    en.wikipedia.org/wiki/Physical_Address_Extension

    This means that 48 bits of virtual page number are translated, giving a virtual address space of up to 256 TB. For some processors, a mode can be enabled with a fifth table, the 512-entry page-map level 5 table ; this means that 57 bits of virtual page number are translated, giving a virtual address space of up to 128 PB.

  5. List of RAM drive software - Wikipedia

    en.wikipedia.org/wiki/List_of_RAM_drive_software

    An affordable RAM Disk compatible with all Windows Workstation and Server OS versions (32- and 64-bit) starting from Windows 2000. The content of the RAM Disk can be made 'persisted' i.e. saved to an image file on the hard disk at regular times and/or at shutdown, and restored from the same image file at boot time.

  6. Memory virtualization - Wikipedia

    en.wikipedia.org/wiki/Memory_virtualization

    Virtual memory systems abstract between physical RAM and virtual addresses, assigning virtual memory addresses both to physical RAM and to disk-based storage, expanding addressable memory, but at the cost of speed. NUMA and SMP architectures optimize memory allocation within multi-processor systems. While these technologies dynamically manage ...

  7. Page (computer memory) - Wikipedia

    en.wikipedia.org/wiki/Page_(computer_memory)

    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]

  9. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    Most modern operating systems employ a method of extending RAM capacity, known as "virtual memory". A portion of the computer's hard drive is set aside for a paging file or a scratch partition , and the combination of physical RAM and the paging file form the system's total memory.
