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. 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 ...

4. GPU virtualization - Wikipedia

   en.wikipedia.org/wiki/GPU_virtualization

   GPU virtualization refers to technologies that allow the use of a GPU to accelerate graphics or GPGPU applications running on a virtual machine.GPU virtualization is used in various applications such as desktop virtualization, [1] cloud gaming [2] and computational science (e.g. hydrodynamics simulations).

5. Intel 5-level paging - Wikipedia

   en.wikipedia.org/wiki/Intel_5-level_paging

   4-level paging of the 64-bit mode. In the 4-level paging scheme (previously known as IA-32e paging), the 64-bit virtual memory address is divided into five parts. The lowest 12 bits contain the offset within the 4 KiB memory page, and the following 36 bits are evenly divided between the four 9 bit descriptors, each linking to a 64-bit page table entry in a 512-entry page table for each of the ...

6. Category:Virtual memory - Wikipedia

   en.wikipedia.org/wiki/Category:Virtual_memory

   A computer design feature that permits software to use more main memory (the memory which the CPU can read and write to directly) than the computer actually physically possesses. Pages in category "Virtual memory"

7. Thrashing (computer science) - Wikipedia

   en.wikipedia.org/wiki/Thrashing_(computer_science)

   Thrashing occurs when there are too many pages in memory, and each page refers to another page. Real memory reduces its capacity to contain all the pages, so it uses 'virtual memory'. When each page in execution demands that page that is not currently in real memory (RAM) it places some pages on virtual memory and adjusts the required page on RAM.

8. Computer memory - Wikipedia

   en.wikipedia.org/wiki/Computer_memory

   If needed, contents of the computer memory can be transferred to storage; a common way of doing this is through a memory management technique called virtual memory. Modern computer memory is implemented as semiconductor memory, [5] [6] where data is stored within memory cells built from MOS transistors and other components on an integrated ...

9. Virtualization - Wikipedia

   en.wikipedia.org/wiki/Virtualization

   A virtual machine implements functionality of a (physical) computer with an operating system. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or virtual machine monitor. [2] Software executed on these virtual machines is separated from the underlying hardware resources.
