21 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." -
22 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." -
23 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." -
24 CD-ROM drive
"An electromechancial device that reads data on CD-ROMs. Most CD-ROM drives have a SCSI interface, although some are connected to a PC via a controller for a disk drive. Data is read through a small laser that is focused on the surface of the CD-ROM through optical mirrors in the read/write head. A spindle and drive motor revolve the CD-ROM, so all data, which is stored in spirals from the center, can be read." -
25 protection
"The process of protecting data from loss or corruption by centrally creating and maintaining replicas and shadow copies of the data. DPM is designed to provide short-term disk-based backup, to support rapid and reliable recovery of data." -
26 boot sector
"A critical disk structure for starting your computer, located at sector 1 of each volume or floppy disk. It contains executable code and data that is required by the code, including information used by the file system to access the volume. The boot sector is created when your format the volume." -
27 junction point
A physical location on a hard disk that points to data located at another location on your hard disk or another storage device. Junction points are created when you create a mounted drive. You can also create a junction point using the linked command. -
28 self-monitoring, analysis, and reporting technology
"An industry-standard, reliability-prediction indicator for both IDE/ATA and SCSI hard disk drives. SMART provides early warning for some hard disk drive failures so that critical data can be protected."English-Arabic terms dictionary > self-monitoring, analysis, and reporting technology

29 SMART
"An industry-standard, reliability-prediction indicator for both IDE/ATA and SCSI hard disk drives. SMART provides early warning for some hard disk drive failures so that critical data can be protected." -
30 Windows Live OneCare safety scanner
"The free online on-demand tool that conducts three types of scans: the protection scan checks for and removes things like viruses and malware; the clean-up scan checks the hard disk for unnecessary files and helps users decide which ones they can safely remove, and also clears the computer's registry of orphaned data; the tune-up scan helps improve the computer's performance by defragmenting the hard disk."English-Arabic terms dictionary > Windows Live OneCare safety scanner

33 DVD
"A form of storage characterized by high capacity (roughly 650 MB) and the use of laser optics rather than magnetic means for reading data. Optical disk storage commonly used for audio, video, and computer data. DVDs range in capacity from 4.7 GB to 17 GB, and can store significantly more than a CD-ROM." -
34 storage engine
"A component of SQL Server that is responsible for managing the raw physical data in your database. For example, reading and writing the data to disk is a task handled by the storage engine." -
35 back up
"To make a duplicate copy of a program, a disk, or data." -
36 backup
"A duplicate of a program, a disk, or data, made either for archiving purposes or for safeguarding files." -
37 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)." -
38 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 -
39 index
"A listing of keywords and associated data that point to the location of more comprehensive information, such as files and records on a disk or record keys in a database." -
40 source
"A disk, file, document, or other collection of information from which data is taken or moved."
