- 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.
- constantinopolitan creed — a formal statement of the chief tenets of Christian belief, adopted by the first Nicene Council.
- consultant paediatrician — a paediatrician who has attained the rank of consultant
- 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.
- correspondence principle — the principle that the laws of quantum mechanics and of any new theory that may be developed reduce to the laws of Newtonian mechanics and electromagnetic theory when applied to systems in which Planck's constant can be regarded as negligible, wavelengths are comparatively small, dimensions are relatively large, etc.

- 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.
