  • discrete fourier transform — (mathematics)   (DFT) A Fourier transform, specialized to the case where the abscissas are integers. The DFT is central to many kinds of signal processing, including the analysis and compression of video and sound information. A common implementation of the DFT is the Fast Fourier Transform (FFT). See also discrete cosine transform.
  • divorce from bed and board — a form of divorce whereby the parties are prohibited from living together but the marriage is not dissolved
  • do it right the first time — (chat)   (DIRFT) A programming approach that aims to avoid the overheads of debugging and testing incomplete or incorrect code by careful specification, design and implementation. DIRFT contrasts with rapid prototyping which emphasises the benefits of having running code as soon as possible, even if it is not perfect. DIRFT is appropriate in the rare cases where the requirements are well understood and unlikely to change, e.g. reimplementing exactly the same function in a different language.
  • dual in-line memory module — (storage)   Small circuit boards carrying memory integrated circuits, with signal and power pins on both sides of the board, in contrast to single-in-line memory modules (SIMM). The individual gold or lead connectors (pins) on SIMMs, although they are on both sides of the chip, are connected to the same memory chip, while on a DIMM, the connections on each side of the module connect to different chips. This allows for a wider data path, as more modules can be accessed at once. DIMM pins are arranged in a zigzag design to allow PCB tracks to pass between them. The 8-byte DIMM format with dual-sided contacts can accommodate 4- and 16-megabit dynamic RAM chips, and is predicted to handle 64- and 256-Mbit devices. The 8-byte DIMM will hold up to 32 megabytes of memory using 16-Mbit DRAMs, but with the 256-Mbit future-generation DRAM, it will be able to hold a 64-Mx64 configuration. Another variation, the 72-pin SO-DIMM, is designed to connect directly to 32 bit data buses, and is intended for use in memory-expansion applications in notebook computers. A Dual in-line memory module (DIMM), as opposed to SIMMs (used by the majority of the PC industry) allows for a 128-bit data path by interleaving memory on alternating memory access cycles. SIMMs on the other hand, have a 64-bit data path. Suppliers are unanimous in their belief that the DIMM will eventually replace the SIMM as the market's preferred memory module.
  • electrochemical equivalent — the mass of an element liberated from its ions or converted into them by one coulomb of electric charge
  • electronic countermeasures — (in electronic warfare) actions intended to interfere with an enemy's use of electromagnetic radiation equipment

  • every other day/week/month — If something happens, for example, every other day or every other month, there is a day or month when it does not happen between each day or month when it happens.
  • expanded memory page frame — (storage)   The part of the IBM PC reserved memory address space used by EMS.
  • exponential-time algorithm — (complexity)   An algorithm (or Turing Machine) that is guaranteed to terminate within a number of steps which is a exponential function of the size of the problem. For example, if you have to check every number of n digits to find a solution, the complexity is O(10^n), and if you add an extra digit, you must check ten times as many numbers. Even if such an algorithm is practical for some given value of n, it is likely to become impractical for larger values. This is in contrast to a polynomial-time algorithm which grows more slowly. See also computational complexity, polynomial-time, NP-complete.
  • extemporaneous preparation — An extemporaneous preparation is a drug specially prepared by a pharmacist because an appropriate drug is not readily available.
  • external-combustion engine — a heat engine in which the working fluid is heated in an external boiler or heat exchanger and is thus isolated from the process of fuel combustion
  • first marquis of lansdowne — Richard, born 1937, U.S. racing-car driver.
  • first-past-the-post system — a voting system in which a candidate may be elected by a simple majority rather than an absolute majority
  • fourth generation computer — (architecture)   A computer built using Very Large Scale Integration (VLSI) integrated circuits, especially a microcomputer based on a microprocesseor, or a parallel processor containing two to thousands of CPUs. VLSI made it routine to fabricate an entire CPU, main memory, or similar device with a single integrated circuit that can be mass produced at very low cost. This has resulted in new classes of machines such as personal computers, and high performance parallel processors that contains thousands of CPUs.
  • fowler-nordheim tunnelling — (electronics)   (US: "tunneling") The quantum mechanical effect exploited in EAPROM and Flash Erasable Programmable Read Only Memory. It differs from Frenkel-Pool Tunnelling in that it does not rely on defects in the semiconductor.
