  • cryptographer — the science or study of the techniques of secret writing, especially code and cipher systems, methods, and the like. Compare cryptanalysis (def 2).
  • cryptographic — Relating to cryptography.

  • daguerrotypes — Plural form of daguerrotype, a misspelling of daguerreotype.
  • data striping — (storage)   Segmentation of logically sequential data, such as a single file, so that segments can be written to multiple physical devices (usually disk drives) in a round-robin fashion. This technique is useful if the processor is capable of reading or writing data faster than a single disk can supply or accept it. While data is being transferred from the first disk, the second disk can locate the next segment. Data striping is used in some modern databases, such as Sybase, and in certain RAID devices under hardware control, such as IBM's RAMAC array subsystem (9304/9395). Data striping is different from, and may be used in conjunction with, mirroring.
  • daylight lamp — a lamp whose light has a range of wavelengths similar to that of natural sunlight
  • decrepitating — Present participle of decrepitate.
  • deemphasizing — Present participle of deemphasize.
  • demand paging — (memory management)   A kind of virtual memory where a page of memory will be paged in if an attempt is made to access it and it is not already present in main memory. This normally involves a memory management unit which looks up the virtual address in a page map to see if it is paged in. If it is not then the operating system will page it in, update the page map and restart the failed access. This implies that the processor must be able to recover from and restart a failed memory access or must be suspended while some other mechanism is used to perform the paging. Paging in a page may first require some other page to be moved from main memory to disk ("paged out") to make room. If this page has not been modified since it was paged in, it can simply be reused without writing it back to disk. This is determined from the "modified" or "dirty" flag bit in the page map. A replacement algorithm or policy is used to select the page to be paged out, often this is the least recently used (LRU) algorithm.
  • demographical — of or relating to demography, the science of vital and social statistics.
  • dendrophagous — feeding on the wood of trees, as certain insects.
  • deng xiaoping — 1904–97, Chinese Communist statesman; deputy prime minister (1973–76; 1977–80) and the dominant figure in the Chinese government from 1977 until his death. He was twice removed from office (1967–73, 1976–77) and rehabilitated. He introduced economic liberalization, but suppressed demands for political reform, most notably in 1989 when over 2500 demonstrators were killed by the military in Tiananmen Square in Beijing

  • dephlegmation — the act of dephlegmating
  • deprecatingly — to express earnest disapproval of.
  • deprivatizing — Present participle of deprivatize.
  • dermatography — a treatise or writing concerning the skin
  • dermographism — dermatographia.
  • diageotropism — a diatropic response of plant parts, such as rhizomes, to the stimulus of gravity
  • diaphragmatic — of the diaphragm.
  • diaphragmitis — inflammation of the diaphragm, phrenitis
  • digitipinnate — (of a compound leaf) digitate with pinnate leaflets.
  • digraphically — in a digraphic manner
  • diphthongally — in a diphthongal manner

  • disappointing — failing to fulfill one's hopes or expectations: a disappointing movie; a disappointing marriage.
  • discographies — Plural form of discography.
  • disparagement — the act of disparaging.
  • disparagingly — that disparages; tending to belittle or bring reproach upon: a disparaging remark.
  • dispraisingly — By way of dispraise.
  • dna computing — (architecture)   The use of DNA molecules to encode computational problems. Standard operations of molecular biology can then be used to solve some NP-hard search problems in parallel using a very large number of molecules. The exponential scaling of NP-hard problems still remains, so this method will require a huge amount of DNA to solve large problems.
  • doppelgangers — Plural form of doppelganger.
  • drag and drop — A common method for manipulating files (and sometimes text) under a graphical user interface or WIMP environment. The user moves the pointer over an icon representing a file and presses a mouse button. He holds the button down while moving the pointer (dragging the file) to another place, usually a directory viewer or an icon for some application program, and then releases the button (dropping the file). The meaning of this action can often be modified by holding certain keys on the keyboard at the same time. Some systems also use this technique for objects other than files, e.g. portions of text in a word processor. The biggest problem with drag and drop is does it mean "copy" or "move"? The answer to this question is not intuitively evident, and there is no consensus for which is the right answer. The same vendor even makes it move in some cases and copy in others. Not being sure whether an operation is copy or move will cause you to check very often, perhaps every time if you need to be certain. Mistakes can be costly. People make mistakes all the time with drag and drop. Human computer interaction studies show a higher failure rate for such operations, but also a higher "forgiveness rate" (users think "silly me") than failures with commands (users think "stupid machine"). Overall, drag and drop took some 40 times longer to do than single-key commands.
  • drake passage — a strait between S South America and the South Shetland Islands, connecting the Atlantic and Pacific oceans.
  • drape forming — thermoforming of plastic sheeting over an open mold by a combination of gravity and a vacuum.

  • drum paneling — flush paneling in a door.
  • ear-splitting — ear-piercing: an earsplitting explosion.
  • earning power — business: ability to profit
  • eavesdropping — to listen secretly to a private conversation.
  • egyptological — Alternative form of Egyptological.
  • electrographs — Plural form of electrograph.
