- 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.

- destructive distillation — the decomposition of a complex substance, such as wood or coal, by heating it in the absence of air and collecting the volatile products

- evolutionary computation — Computer-based problem solving systems that use computational models of evolutionary processes as the key elements in design and implementation. A number of evolutionary computational models have been proposed, including evolutionary algorithms, genetic algorithms, the evolution strategy, evolutionary programming, and artificial life.
- evolutionary programming — (EP) A stochastic optimisation strategy originally conceived by Lawrence J. Fogel in 1960. An initially random population of individuals (trial solutions) is created. Mutations are then applied to each individual to create new individuals. Mutations vary in the severity of their effect on the behaviour of the individual. The new individuals are then compared in a "tournament" to select which should survive to form the new population. EP is similar to a genetic algorithm, but models only the behavioural linkage between parents and their offspring, rather than seeking to emulate specific genetic operators from nature such as the encoding of behaviour in a genome and recombination by genetic crossover. EP is also similar to an evolution strategy (ES) although the two approaches developed independently. In EP, selection is by comparison with a randomly chosen set of other individuals whereas ES typically uses deterministic selection in which the worst individuals are purged from the population.

- low voltage differential — (hardware) (LVD) A method of driving SCSI cables that will be formalised in the SCSI-3 specifications.

- multiple virtual storage — (operating system) (MVS) Release 2 of OS/VS2, called MVS because it had multiple 16 MB virtual address spaces, in contrast to SVS. MVS ran on the IBM 390 series mainframes. It became MVS/SP, then MVS/XA (with 31-bit addressing) and then MVS/ESA. MVS/Open Edition (MVS/OE), aimed at the growing open systems market, added TCP/IP and Unix support in an MVS address space, allowing users to run IBM, CICS-type applications, batch applications and Unix. MVS/ESA was repackaged as OS/390 as a marketing exercise but it's basically the same thing. Version: 5.1.
