241 Glossary D data: Information that a computer can process. The word "data" is actually plural for "datum," meaning a single piece of information. data bits: A data communications parameter controlling the number of bits used to represent a character. If data bits = 7, the computer can generate 128 unique characters, if data bits = 8, the computer can generate 256 unique characters. decimal: The base-ten numbering system normally used by people. Computers, in contrast, generally use binary or hexadecimal numbering systems. See also binary, hexadecimal. default: The values or options selected by the processor, a controller or program when you do not specify a setting. For example, a preset value in a dialog box or window. delete: To remove information. Examples are removing a line of text from within a program or removing files from a disk or other storage device. Synonymous with erase. deselect: To remove highlighting from text, such as an item in a list or menu, or to remove handles from graphical objects. device: A component attached to the computer. Internal devices include the hard disk and screen. External devices you can connect to the computer include a monitor, printer and port replicator. device driver: A program that controls the operation of a specific device such as the screen, CD-ROM drive or printer. The operating system loads many device drivers when you turn on the computer. dialog box: 1) A box requesting information. Typically it contains a combination of buttons, lists and text-entry boxes. 2) A box containing a message. It may tell you that a process has completed successfully. Alternatively, it may be a warning that the computer cannot do what you asked or that obeying your instructions may destroy data. This second type of dialog box is also called a message box. DIMM: Dual Inline Memory Module. A unit of RAM used for memory expansion. direct current (DC): Electric current that flows in one direction. This type of power is usually supplied by batteries.
