2 Data Protection API
"A set of routines, protocols, and tools that provides information confidentiality to user and system processes by applying password-based cryptographic protection at the local operating system level." -
3 Boot Configuration Data
A data store that contains boot configuration parameters and controls how the operating system is started beginning with Windows Vista or Windows Server 2008. -
4 RAID-5 volume
"A fault-tolerant volume with data and parity striped intermittently across three or more physical disks. Parity is a calculated value that is used to reconstruct data after a failure. If a portion of a physical disk fails, Windows recreates the data that was on the failed portion from the remaining data and parity. You can create RAID-5 volumes only on dynamic disks on computers running the Windows 2000 Server or Windows Server 2003 families of operating systems. You cannot mirror or extend RAID-5 volumes. In Windows NT 4.0, a RAID-5 volume was known as a striped set with parity." -
5 mirrored volume
"A fault-tolerant volume that duplicates data on two physical disks. A mirrored volume provides data redundancy by using two identical volumes, which are called mirrors, to duplicate the information contained on the volume. A mirror is always located on a different disk. If one of the physical disks fails, the data on the failed disk becomes unavailable, but the system continues to operate in the mirror on the remaining disk. You can create mirrored volumes only on dynamic disks on computers running the Windows 2000 Server or Windows Server 2003 families of operating systems. You cannot extend mirrored volumes." -
6 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." -
7 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." -
8 crash
"The failure of either a program or a disk drive. A program crash results in the loss of all unsaved data and can leave the operating system unstable enough to require restarting the computer. A disk drive crash, sometimes called a disk crash, leaves the drive inoperable and can cause loss of data." -
9 format
"To prepare a disk for use by organizing its storage space into a collection of data ""compartments"", each of which can be located by the operating system so that data can be sorted and retrieved. When a previously used disk is formatted, any preexisting information on it is lost." -
10 PowerPC
"A microprocessor architecture developed in 1992 by Motorola and IBM, with some participation by Apple. A PowerPC microprocessor is RISC-based and superscalar, with a 64-bit data bus and 32-bit address bus. It also has separate data and instruction caches, although the size of each varies by implementation. All PowerPC microprocessors have multiple integer and floating-point units. The voltage and operating speed varies with the implementation. Starting with the PowerPC 740, the microprocessors were manufactured with copper, instead of aluminum, for better performance and reliability." -
11 Extensible Markup Language
A markup language for describing and exchanging structured data in a format that is independent of operating systems and applications. XML is a World Wide Web Consortium (W3C) specification and is a subset of Standard Generalized Markup Language (SGML).English-Arabic terms dictionary > Extensible Markup Language
-
12 XML
A markup language for describing and exchanging structured data in a format that is independent of operating systems and applications. XML is a World Wide Web Consortium (W3C) specification and is a subset of Standard Generalized Markup Language (SGML). -
13 bad sector
"A disk sector that cannot be used for data storage, usually because of media damage or imperfections. Finding, marking, and avoiding bad sectors on a disk is one of the many tasks performed by a computer's operating system. A disk-formatting utility can also find and mark the bad sectors on a disk." -
14 current directory
The first directory in which the operating system looks for programs and data files and stores files for output. -
15 fault tolerance
"The ability of computer hardware or software to ensure data integrity when hardware failures occur. Fault-tolerant features appear in many server operating systems and include mirrored volumes, RAID-5 volumes, and server clusters." -
16 object type
"An opaque data structure that defines a protected entity that is implemented and manipulated by the operating system. For example, the system service that reads a file operates on an open file object." -
17 RAID
"A mechanism for storing identical data on multiple disks for redundancy, improved performance, and increased mean time between failures (MTBF). RAID provides fault tolerance and appears to the operating system as a single logical drive." -
18 Redundant Array of Independent Disks
"A mechanism for storing identical data on multiple disks for redundancy, improved performance, and increased mean time between failures (MTBF). RAID provides fault tolerance and appears to the operating system as a single logical drive."English-Arabic terms dictionary > Redundant Array of Independent Disks
-
19 TDS
"The SQL Server internal client/server data transfer protocol. TDS allows client and server products to communicate regardless of operating-system platform, server release, or network transport." -
20 BCD
A data store that contains boot configuration parameters and controls how the operating system is started beginning with Windows Vista or Windows Server 2008.
