24-letter words containing a, c, r, e, d
- data encryption standard — (DES) The NBS's popular, standard encryption algorithm. It is a product cipher that operates on 64-bit blocks of data, using a 56-bit key. It is defined in FIPS 46-1 (1988) (which supersedes FIPS 46 (1977)). DES is identical to the ANSI standard Data Encryption Algorithm (DEA) defined in ANSI X3.92-1981. DES has been implemented in VLSI. SunOS provides a des command which can make use of DES hardware if fitted. Neither the software nor the hardware are supposed to be distributed outside the USA.

- dejeuner a la fourchette — a luncheon or light meal, especially one at which eggs, meat, etc., are served.
- delayed control-transfer — (architecture) A technique used on the SPARC processor to reduce the effect of pipeline breaks by executing the instruction after a branch instruction (the "delay instruction" in the "delay slot"). If there is no useful instruction which can be placed in the delay slot then the "annul bit" on the control transfer instruction can be set, preventing execution of the delay instruction (unless the control transfer is conditional and is taken). Annulled branches are indicated in SPARC assembler language by appending ",A" to the operation code. For example, LOOP: ... CMP %L0,10 BLE,A LOOP ADD %L2, %L3, #L4 If the delay instruction is also a control transfer instruction then it gets more complicated. Both control transfer instructions are executed (but not the following instruction) and, assuming they are both taken, control is transferred briefly to the destination of the first and then immediately to the destination of the second.

- forward error correction — (algorithm) (FEC) A class of methods for controling errors in a one-way communication system. FEC sends extra information along with the data, which can be used by the receiver to check and correct the data. A CPU writing data to RAM is a kind of one-way communication - see error correcting memory and error checking and correction.

- hardware circular buffer — (programming, hardware) digital signal processors which support hardware circular buffers automatically generate and increment pointers for memory accesses which wrap to the beginning of the buffer when its end is reached, thus saving the time and instructions otherwise needed to ensure that the address pointer stays within the boundary of the buffer, and speeding the execution of repetitive DSP algorithms.

- hierarchical data format — (file format, data) (HDF) A library and multi-object file format for the transfer of graphical and numerical data between computeres. The freely available HDF distribution consists of the library, command line utilities, test suite source, Java interface, and the Java-based HDF Viewer (JHV). HDF supports several different data models, including multidimensional arrays, raster images, and tables. Each defines a specific aggregate data type and provides an API for reading, writing, and organising the data and metadata. New data models can be added by the HDF developers or users. HDF is self-describing, allowing an application to interpret the structure and contents of a file without any outside information. One HDF file can hold a mixture of related objects which can be accessed as a group or as individual objects. Users can create their own grouping structures called "vgroups". HDF files can be shared across most common platforms, including many workstations and high performance computers. An HDF file created on one computer can be read on a different system without modification.
- ichthyophthirius-disease — ich.
- implicit differentiation — a method of finding the derivative of an implicit function by taking the derivative of each term with respect to the independent variable while keeping the derivative of the dependent variable with respect to the independent variable in symbolic form and then solving for that derivative.
