1 basic disk
"A physical disk that can be accessed by MS-DOS and all Windows-based operating systems. Basic disks can contain up to four primary partitions, or three primary partitions and an extended partition with multiple logical drives." -
2 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." -
3 domain tree
"In DNS, the inverted hierarchical tree structure that is used to index domain names. Domain trees are similar in purpose and concept to the directory trees used by computer filing systems for disk storage. For example, when numerous files are stored on disk, directories can be used to organize the files into logical collections. When a domain tree has one or more branches, each branch can organize domain names used in the namespace into logical collections." -
4 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)." -
5 multiboot
"A computer configuration in which two or more different operating systems are installed on the same computer hard disk, and you can choose which operating system to use when the computer starts." -
6 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." -
7 text-mode Setup
"The second of the three stages of Setup, where the basic hardware of the computer (CPU, motherboard, hard disk controllers, file systems, and memory) is determined, the base operating system necessary to continue is installed, and specified folders are created." -
8 map control block
A structure that file systems use to map the virtual block numbers (VBNs) for a file to the corresponding logical block numbers (LBNs) on the disk. -
9 MCB
A structure that file systems use to map the virtual block numbers (VBNs) for a file to the corresponding logical block numbers (LBNs) on the disk. -
10 sparing table
A remapping table in the UDF file format that allows defect management with disk/drive systems that do not typically perform defect management (e.g. CD-RW) by reallocating the data at the file system layer when a defective block is encountered. -
11 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."
