21 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." -
22 paged pool
"The system-allocated virtual memory that has been charged to a process and that can be paged. Paging is the moving of infrequently used parts of a program's working memory from random access memory (RAM) to another storage medium, usually the hard disk." -
23 page
"In virtual memory systems, a unit of data storage that is brought into random access memory (RAM), typically from a hard drive, when a requested item of data is not already in RAM." -
24 storage
"In computing, any device in or on which information can be kept. Microcomputers have two main types of storage: random access memory (RAM) and disk drives and other external storage media. Other types of storage include read-only memory (ROM) and buffers." -
25 cache
A special memory subsystem in which frequently used data values are duplicated for quick access. -
26 caching
The process of temporarily storing recently accessed information in a special memory subsystem for quicker access. -
27 cache
To store frequently used data values in a special memory subsystem for quick access. -
28 fast page-mode RAM
A specially designed dynamic RAM that supports access to sequential memory locations with a reduced cycle time. -
29 FPM RAM
A specially designed dynamic RAM that supports access to sequential memory locations with a reduced cycle time. -
30 GDT
"A memory segment that contains descriptors for code, data, and descriptor table segments. All processor tasks have access to a common GDT." -
31 global descriptor table
"A memory segment that contains descriptors for code, data, and descriptor table segments. All processor tasks have access to a common GDT." -
32 kernel mode
"A highly privileged mode of operation where program code has direct access to all memory, including the address spaces of all user-mode processes and applications, and to hardware." -
33 mutual exclusion
"A programming technique that ensures that only one program or routine at a time can access some resource, such as a memory location, an I/O port, or a file, often through the use of semaphores, which are flags used in programs to coordinate the activities of more than one program or routine." -
34 RAM cache
Cache memory that is used by the system to store and retrieve data from the RAM. Frequently accessed segments of data may be stored in the cache for quicker access compared with secondary storage devices such as disks. -
35 TLB
A table used in a virtual memory system that lists the physical address page number associated with each virtual address page number. A TLB is used in conjunction with a cache whose tags are based on virtual addresses. The virtual address is presented simultaneously to the TLB and to the cache so that cache access and virtual-to-physical address translation can occur simultaneously. -
36 supervisor mode
"A highly privileged mode of operation where program code has direct access to all memory, including the address spaces of all user-mode processes and applications, and to hardware." -
37 protected mode
"A highly privileged mode of operation where program code has direct access to all memory, including the address spaces of all user-mode processes and applications, and to hardware." -
38 Ring 0
"A highly privileged mode of operation where program code has direct access to all memory, including the address spaces of all user-mode processes and applications, and to hardware." -
39 dynamic RAM
A form of semiconductor random access memory (RAM). -
40 degradation
"In computer systems, a reduction in level of performance or service. Degradation in microcomputer performance is indicated by slow response times or frequent pauses for disk access because memory is insufficient to hold an entire program plus the data the program is using."
