  • command interpreter — (operating system)   A program which reads textual commands from the user or from a file and executes them. Some commands may be executed directly within the interpreter itself (e.g. setting variables or control constructs), others may cause it to load and execute other files. When an IBM PC is booted BIOS loads and runs the MS-DOS command interpreter into memory from file COMMAND.COM found on a floppy disk or hard disk drive. The commands that COMMAND.COM recognizes (e.g. COPY, DIR, PRN) are called internal commands, in contrast to external commands which are executable files.
  • command line option — (software)   (Or "option", "flag", "switch", "option switch") An argument to a command that modifies its function rather than providing data. Options generally start with "-" in Unix or "/" in MS-DOS. This is usually followed by a single letter or occasionally a digit. More recently, GNU software adopted the --longoptionname style, usually in addition to traditional, single-character, -x style equivalents. Some commands require each option to be a separate argument, introduced by a new "-" or "/", others allow multiple option letters to be concatenated into a single argument with a single "-" or "/", e.g. "ls -al". A few Unix commands (e.g. ar, tar) allow the "-" to be omitted. Some options may or must be followed by a value, e.g. "cc prog.c -o prog", sometimes with and sometimes without an intervening space.

  • differential backup — (operating system)   A kind of backup that copies all files that have changed since the last full backup. Each differential backup will include all files in previous differential backups since the full backup so to restore a version of a file, you only need to search the full backup and the relevant differential backup. Some systems support differential backup by associating an "Archive" flag with each file and setting this flag whenever the file is modified to indicate that it should be included in the next backup. A differential backup does not change this flag, whereas an incremental backup resets it.
  • diffraction pattern — the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.
  • digital linear tape — (storage)   (DLT) A kind of magnetic tape drive originally developed by DEC and now marketed by Quantum. DLT drives implement the Digital Lempel Ziv 1 (DLZ1) compression algorithm in a combination of hardware and firmware. They use a popular chip by Stac (now hi/fn) to do the string searching. Counting, sorting and Huffman coding are done in firmware (with hardware support for the Huffman algorithm?). In April 1997 DLT drives can transfer 5 megabytes per second and can store 35 gigabytes on a single cartridge. Compression might roughly double these figures.
  • digital photography — the taking or manipulation of photographs that are stored as data files on a computer.
  • diplomatic immunity — exemption from taxation, searches, arrest, etc., enjoyed by diplomatic officials and their dependent families under international law, and usually on a reciprocal basis.
  • direct mapped cache — (architecture)   A cache where the cache location for a given address is determined from the middle address bits. If the cache line size is 2^n then the bottom n address bits correspond to an offset within a cache entry. If the cache can hold 2^m entries then the next m address bits give the cache location. The remaining top address bits are stored as a "tag" along with the entry. In this scheme, there is no choice of which block to flush on a cache miss since there is only one place for any block to go. This simple scheme has the disadvantage that if the program alternately accesses different addresses which map to the same cache location then it will suffer a cache miss on every access to these locations. This kind of cache conflict is quite likely on a multi-processor. See also fully associative cache, set associative cache.
  • directional coupler — (communications)   (tap) A passive device used in cable systems to divide and combine radio frequency signals. A directional coupler has at least three ports: line in, line out, and the tap. The signal passes between line in and line out ports with loss referred to as the insertion loss. A small portion of the signal power applied to the line in port passes to the tap port. A signal applied to the tap port is passed to the line in port less the tap attenuation value. The tap signals are isolated from the line out port to prevent reflections. A signal applied to the line out port passes to the line in port and is isolated from the tap port. Some devices provide more than one tap output line (multi-taps).
  • disambiguation page — a page on a website that lists various websites or web pages that have or could have the same title. The user is able to select from the list that page, site etc that he or she actually wants
