- 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.
- 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).
