- consonantal alliteration — the use of the same consonant at the beginning of each word or each stressed syllable in a line of verse, as in around the rock the ragged rascal ran
- constant linear velocity — (storage) (CLV) A way of controlling the rotation of the disks in a disk drive in which the linear velocity of the disk surface relative to the read/write heads is kept constant. In order to achieve constant linear velocity, the disk must rotate faster (at a higher angular velocity) when reading or writing tracks closer to the centre. Having a constant linear read/write speed along the track means that the electrical signal to and from the heads has a constant data rate (bits per second), thus simplifying the timing of the drive electronics somewhat. However, rotating at less than the maximum possible rate sacrifices some potential performance compared to the alternative, constant angular velocity. Also, varying the rate causes more vibration and consumes more energy.

- cooperative multitasking — (parallel, operating system) A form of multitasking where it is the responsibility of the currently running task to give up the processor to allow other tasks to run. This contrasts with pre-emptive multitasking where the task scheduler periodically suspends the running task and restarts another. Cooperative multitasking requires the programmer to place calls at suitable points in his code to allow his task to be descheduled which is not always easy if there is no obvious top-level main loop or some routines run for a long time. If a task does not allow itself to be descheduled all other tasks on the system will appear to "freeze" and will not respond to user action. The advantage of cooperative multitasking is that the programmer knows where the program will be descheduled and can make sure that this will not cause unwanted interaction with other processes. Under pre-emptive multitasking, the scheduler must ensure that sufficient state for each process is saved and restored that they will not interfere. Thus cooperative multitasking can have lower overheads than pre-emptive multitasking because of the greater control it offers over when a task may be descheduled. Cooperative multitasking is used in RISC OS, Microsoft Windows and Macintosh System 7.

- 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.

- glasgow haskell compiler — (language) (GHC) A Haskell 1.2 compiler written in Haskell by the AQUA project at Glasgow University, headed by Simon Peyton Jones <[email protected]> throughout the 1990's [started?]. GHC can generate either C or native code for SPARC, DEC Alpha and other platforms. It can take advantage of features of gcc such as global register variables and has an extensive set of optimisations. GHC features an extensible I/O system based on a "monad", in-line C code, fully fledged unboxed data types, incrementally-updatable arrays, mutable reference types, generational garbage collector, concurrent threads. Time and space profiling is also supported. It requires GNU gcc 2.1+ and Perl. GHC runs on Sun-4, DEC Alpha, Sun-3, NeXT, DECstation, HP-PA and SGI. E-mail: <[email protected]>.
