A technique for spreading data over multiple disk drives. Disk striping can speed up operations that retrieve data from disk storage. The computer system breaks a body of data into units and spreads these units across the available disks. Systems that implement disk striping generally allow the user to select the data unit size or stripe width.
Disk striping is available in two types. Single user striping uses relatively large data units, and improves performance on a single-user workstation by allowing parallel transfers from different disks. Multi-user striping uses smaller data units and improves performance in a multi-user environment by allowing simultaneous (or overlapping) read operations on multiple disk drives.
Disk striping stores each data unit in only one place and does not offer protection from disk failure.
(v) To make data or images appear on a monitor. (n) Short for display screen or monitor.
In graphics and video editing dissolve is a term used to describe a transition effect in which one video clip (or one image) is gradually fads out while another image simultaneously replaces the original one. Also called video dissolve, film dissolve, or linear light blend. The overall objective is for the image or clip to […]
- Distance Learning
A type of education, typically college-level, where students work on their own at home or at the office and communicate with faculty and other students via e-mail, electronic forums, videoconferencing, chat rooms, bulletin boards, instant messaging and other forms of computer-based communication. Most distance learning programs include a computer-based training (CBT) system and communications tools […]
- distributed computing
A type of computing in which different components and objects comprising an application can be located on different computers connected to a network. So, for example, a word processing application might consist of an editor component on one computer, a spell-checker object on a second computer, and a thesaurus on a third computer. In some […]
- distributed database
A database that consists of two or more data files located at different sites on a computer network. Because the database is distributed, different users can access it without interfering with one another. However, the DBMS must periodically synchronize the scattered databases to make sure that they all have consistent data.
