1 physical memory
"The amount of RAM memory in a system, as distinguished from virtual memory." -
2 physical address extension
"A feature that allows x86-based computers to support more than 4 gigabytes (GB) of physical memory. Up to 64 GB of physical memory can be used as regular 4-kilobyte (KB) pages, and the number of bits that can be used by the kernel to address physical memory can be expanded from 32 to 36."English-Arabic terms dictionary > physical address extension

3 physical address expansion
"A feature that allows x86-based computers to support more than 4 gigabytes (GB) of physical memory. Up to 64 GB of physical memory can be used as regular 4-kilobyte (KB) pages, and the number of bits that can be used by the kernel to address physical memory can be expanded from 32 to 36."English-Arabic terms dictionary > physical address expansion
-
4 memory card
"In a server cluster, a resource that can act as the cluster's quorum resource. To be quorum-capable, a resource must provide shared storage and a means of persistent arbitration. The cluster service defines only physical disk resources as quorum-capable." -
5 Windows Memory Diagnostics Tool
"A feature of Windows Vista that can automatically detect and resolve problems caused by defective physical memory. If the diagnostics module identifies a memory problem, Windows Vista can avoid using the affected portion of physical memory, enabling the operating system to start successfully and avoid application crashes."English-Arabic terms dictionary > Windows Memory Diagnostics Tool
-
6 scatter/gather direct memory access
A form of direct memory access (DMA) in which data is transferred to and from noncontiguous ranges of physical memory.English-Arabic terms dictionary > scatter/gather direct memory access
-
7 Peak Memory Usage
"In Task Manager, the peak amount of physical memory resident in a process since it started." -
8 PAE
"A feature that allows x86-based computers to support more than 4 gigabytes (GB) of physical memory. Up to 64 GB of physical memory can be used as regular 4-kilobyte (KB) pages, and the number of bits that can be used by the kernel to address physical memory can be expanded from 32 to 36." -
9 paging
"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." -
10 paging file
"A hidden file on the hard disk that Windows uses to hold parts of programs and data files that do not fit in memory. The paging file and physical memory, or random access memory (RAM), comprise virtual memory. Windows moves data from the paging file to memory as needed and moves data from memory to the paging file to make room for new data." -
11 swap file
"A hidden file on the hard disk that Windows uses to hold parts of programs and data files that do not fit in memory. The paging file and physical memory, or random access memory (RAM), comprise virtual memory. Windows moves data from the paging file to memory as needed and moves data from memory to the paging file to make room for new data." -
12 pagefile
"A hidden file on the hard disk that Windows uses to hold parts of programs and data files that do not fit in memory. The paging file and physical memory, or random access memory (RAM), comprise virtual memory. Windows moves data from the paging file to memory as needed and moves data from memory to the paging file to make room for new data." -
13 commitment
The memory manager's current systemwide total of memory pages that have been committed to either physical memory or a page file. -
14 backing store
A mass-storage device that serves as backup memory for paging when physical memory is full. -
15 scatter/gather DMA
A form of direct memory access (DMA) in which data is transferred to and from noncontiguous ranges of physical memory. -
16 page frame
"A block of contiguous physical memory that stores the contents of a virtual page. The size of the virtual page and page frame are usually identical. However, the size of a page frame depends on the microprocessor." -
17 file system cache
An area of physical memory that holds frequently used pages. It allows applications and services to locate pages rapidly and reduces disk activity. -
18 working set
The set of pages in the virtual address space of the process that are currently resident in physical memory. -
19 tiled resourcing
"A graphics feature that allows large logical resources to occupy only a small amount of physical memory, which can be dynamically remapped as the relevant application needs it." -
20 virtual address
"In a virtual memory system, the address the application uses to reference memory. The kernel and the memory management unit (MMU) translate this address into a physical address before the memory is actually read or written."
