  • deterministic automaton — (theory)   A finite-state automaton in which the overall course of the computation is completely determined by the program, the starting state, and the initial inputs. The class of problems solvable by such automata is the class P (see polynomial-time algorithm).

  • discrimination learning — a learning process in which an organism learns to react differently to different stimuli
  • disjunctive normal form — (DNF) A logical formula consisting of a disjunction of conjunctions where no conjunction contains a disjunction. E.g. the DNF of (A or B) and C is (A and C) or (B and C).
  • dissociate oneself from — to deny or repudiate any connection with
  • draw/make a distinction — If you draw a distinction or make a distinction, you say that two things are different.
  • drawing exchange format — (DXF) A file format for graphical information, similar to IGES. Commonly used by CAD systems like AutoCAD.
  • electronic mail address — (messaging)   (Usually "e-mail address") The string used to specify the source or destination of an electronic mail message. E.g. "[email protected]". The RFC 822 standard is probably the most widely used on the Internet. X.400 was once used in Europe and Canada. UUCP-style (bang path) addresses or other kinds of source route became virtually extinct in the 1990s. In the example above, "john" is the local part which is the name of a mailbox on the destination computer. If the sender and recipient use the same computer, or the same LAN, for electronic mail then the local part is usually all that is required. If they use different computers, e.g. they work at different companies or use different Internet service providers, then the "host part", e.g. "sales.acme.com" must be appended after an "@". This usually takes the form of a fully qualified domain name or, within a large organisation, it may be just the hostname part, e.g. "sales". The destination computer named by the host part is usually a server of some kind rather than an individual's workstation or PC. The user's mail is stored on the server and read later via client mail software running on the user's computer. Large organisations, such as universities will often set up a global alias directory which maps a simple user name such as "jsmith" to an address which contains more information such as "[email protected]". This hides the detailed knowledge of where the message will be delivered from the sender, making it much easier to redirect mail if a user leaves or moves to a different department for example.
  • embarrassment of riches — If you say that someone has an embarrassment of riches, you mean that they have so many good things that these things are a problem.
  • error correcting memory — (storage)   (ECM) RAM using some kind of error detection and correction (EDAC) scheme. The two types of memory errors in RAM (especially DRAM) are "soft" errors due to radiation-induced bit switching, and "hard" errors due to the unexpected deterioration of a memory chip. Soft errors do not indicate lasting damage to the memory board, but they do corrupt programs or data. Hard errors demand physical repairs. Single bit memory failures are the most common. A hard single bit failure, such as that caused by a completely dead chip can be corrected by EDAC if each chip supplies only one bit of each word. EDAC memory is the most common level of protection for minicomputers and mainframes whereas the cheaper parity protection is more common in microcomputers.
  • execute channel program — (operating system)   (EXCP) An IBM system for low-level file access, where the programmer is completely responsible for providing a list of device-specific "channel comands" to be executed by I/O channels, control units and/or devices. The operating system will simply check the "CCW" chains for security purposes (access invalid memory or outside of file extents) and then schedule them for execution.

  • extremely low frequency — a radio frequency or radio-frequency band below 3 kilohertz
  • extrinsic semiconductor — a semiconductor into which a doping agent has been introduced, giving it different electrical properties than the intrinsic semiconductor

  • functional requirements — (specification)   What a system should be able to do, the functions it should perform.

  • interchange file format — (file format)   (IFF, full name "EA IFF 1985") A generic file format published by Electronic Arts as an open standard. IFF is chunk-based and hierarchical so files can include other files. It is easily extensible and an all round Good Idea. An IFF file starts with one of the following "group IDs": 'FORM', 'LIST' or 'CAT '. This is followed by an unsigned 32-bit number of bytes in the remainder of the file. Then comes an ID that indicates which type of IFF file this is. The main image type is ILBM, audio is either AIFF or 8SVX, animations are ANIM etc. An IFF file will probably have a filename extension related to this file type stored in the file. The rest of the file is divided into chunks each of which also has a four-byte header and byte count.
