41 heap
A portion of memory reserved for a program to use for the temporary storage of data structures whose existence or size cannot be determined until the program is running. -
42 retrieve
"To obtain a specific requested item or set of data by locating it and returning it to a program or to the user. Computers can retrieve information from any source of storage-disks, tapes, or memory." -
43 SMP
"A multiprocessing operation in which multiple processors share the same memory, which contains one copy of the operating system, one copy of any applications that are in use, and one copy of the data. Because the operating system divides the workload into tasks and assigns those tasks to whatever processors are available, SMP reduces transaction time." -
44 symmetric multiprocessing
"A multiprocessing operation in which multiple processors share the same memory, which contains one copy of the operating system, one copy of any applications that are in use, and one copy of the data. Because the operating system divides the workload into tasks and assigns those tasks to whatever processors are available, SMP reduces transaction time." -
45 stack
"A region of reserved memory, organized as a stack, in which programs temporarily store status data such as procedure and function call return addresses, passed parameters, and local variables." -
46 volume bitmap
A stored reference (which may exist both on hierarchical directory volumes and in memory) to every piece of data that is in the allocation blocks and indicates whether the block is allocated or free for use. -
47 base address
The part of a two-part memory address that remains constant and provides a reference point from which the location of a byte of data can be calculated. -
48 blittable type
A data type that has a unique characteristic and an identical presentation in memory for both managed and unmanaged environments. It can be directly shared. -
49 byte order
"The processor memory architecture in which bytes of data (typically, integer values) are stored. The two most common orders are: little endian (least significant byte is placed first) and big endian (most significant byte is placed first)." -
50 map
To associate data with a specified location in memory. -
51 DIMM
A type of memory board comprised of RAM chips mounted on a circuit board with a 64-bit data path and pins on each side that are on different circuits and that respond to different signals. -
52 buffer pool
A block of memory reserved for index and table data pages. -
53 input stream
A flow of information used in a program as a sequence of bytes that are associated with a particular task or destination. Input streams include series of characters read from the keyboard to memory and blocks of data read from disk files. -
54 scatter/gather list
A list of one or more paired base addresses and lengths that describe the physical locations from which to transfer data in scatter/gather direct memory access. -
55 primary storage device
A storage device that holds data in temporary memory such as RAM. -
56 null pointer
"A pointer to nothing: usually a standardized memory address, such as 0. A null pointer usually marks the last of a linear sequence of pointers or indicates that a data search operation has come up empty." -
57 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." -
58 virtualization
"In Windows Presentation Foundation and Silverlight, a technique by which a subset of UI elements are generated from a larger number of data items based on which items are visible on the screen. Virtualization is a performance enhancement, because it is intensive, both in terms of memory and processor, to generate a large number of UI elements when only a few may be on the screen at a given time." -
59 user interface virtualization
"In Windows Presentation Foundation and Silverlight, a technique by which a subset of UI elements are generated from a larger number of data items based on which items are visible on the screen. Virtualization is a performance enhancement, because it is intensive, both in terms of memory and processor, to generate a large number of UI elements when only a few may be on the screen at a given time."English-Arabic terms dictionary > user interface virtualization

60 Vertipaq
A high performance analytics engine that uses compressed in-memory column-oriented storage to manage large volumes of data and deliver fast response to user queries.
