21 query
"A formalized instruction to a data source to either extract data or perform a specified action. The query can be in the form of a query expression, or a method-based query (or a combination of the two). The data source can be in different forms, e.g. relational databases, XML documents, or in-memory objects." -
22 scatter/gather DMA
A form of direct memory access (DMA) in which data is transferred to and from noncontiguous ranges of physical memory. -
23 access
The act of reading data from or writing data to memory. -
24 copy
"To duplicate information and reproduce it in another part of a document, in a different file or memory location, or in a different medium. A copy operation can affect data ranging from a single character to large segments of text, a graphics image, or from one to many data files." -
25 I/O port
A channel through which data is transferred between a device and the microprocessor. The port appears to the microprocessor as one or more memory addresses that it can use to send or receive data.منفذ I/O -
26 input/output port
A channel through which data is transferred between a device and the microprocessor. The port appears to the microprocessor as one or more memory addresses that it can use to send or receive data.منفذ إدخال/إخراج -
27 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. -
28 DDR SDRAM
"A type of SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip’s data throughput." -
29 profiling
"The collection of detailed performance data, such as memory, stack frame, and CPU utilization, during application execution. Analysis of the resulting data often leads to code optimizations that substantially improve application run-time behavior." -
30 AGP
"A technology that provides a dedicated, high-speed port through which large blocks of 3-D texture data can be moved between the computer's graphics controller and system memory." -
31 access
To gain entry to memory in order to read or write data. -
32 accelerated graphics port
"A technology that provides a dedicated, high-speed port through which large blocks of 3-D texture data can be moved between the computer's graphics controller and system memory."منفذ رسومات مسرّع -
33 address
A number specifying a location in memory where data is stored. -
34 bitmap
"A data structure in memory that represents information in the form of a collection of individual bits. A bit map is used to represent a bit image. Another use of a bit map in some systems is the representation of the blocks of storage on a disk, indicating whether each block is free (0) or in use (1)." -
35 cache
A special memory subsystem in which frequently used data values are duplicated for quick access. -
36 buffer
"To use a region of memory to hold data that is waiting to be transferred, especially to or from input/output (I/O) devices such as disk drives and serial ports."يخزن مؤقتاً -
37 cache
To store frequently used data values in a special memory subsystem for quick access. -
38 calculator
"Broadly, any device that performs arithmetic operations on numbers. Sophisticated calculators can be programmed for certain functions and can store values in memory, but they differ from computers in several ways: they have a fixed set of commands, they do not recognize text, they cannot retrieve values stored in a data file, and they cannot find and use values generated by a program such as a spreadsheet." -
39 GDT
"A memory segment that contains descriptors for code, data, and descriptor table segments. All processor tasks have access to a common GDT." -
40 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."
