Disk, английский
- (crop science) an tractor-drawn implement composed of circular plates arranged at an angle with the soil. used to prepare the soil for seeding.
- A flat circular plate, coated with a magnetic material, on which data may be stored by
- Preferred usage (spelling) of the term for reference to magnetic media, such as floppy and hard disks.
- A flat circular plate, coated with a magnetic material, on which data may be stored by selective magnetization of portions of the surface. may be a flexible, floppy disc or rigid hard disk. it could also be a plastic compact disc (cd) or digital video disc (dvd).

Disk, английский
Disk, шведский
Disk, французский
The visible surface of the sun (or any heavenly body) projected against the sky.
Disk (диск), английский
Плоская круглая пластина, покрытая магнитным материалом, на которую записываются данные путем селективного намагничивания частей поверхности. существуют гибкие и жесткие, а также пластиковые компакт-диски (cd) или цифровые видеодиски (dvd).
Disk - disc, английский
A record-like magnetic-coated piece of material that can store digital information; may be a hard disk or pliable floppy disk.
Disk accelerator software, английский
Программный ускоритель дисковых операций
Disk access time, английский
The time needed for a read/write head in a disk drive to locate a track on a disk. access time is usually measured in milliseconds and is used as a performance measure for hard disks and cd-rom drives.
Disk adapter, английский
Адаптер диска
Disk administrator, английский
Администратор диска
Disk allocation blocks, английский
Распределяемые блоки диска; блоки распределения дисковой памяти disk-at-once recording одномоментная запись диска; односеансовая запись диска disk-based с памятью на дисках; оснащенный дисками disk-based version дисковая версия
Disk application interface, английский
Disk arbitration, английский
The process that occurs when the cluster node that owned the quorum resource fails or is unavailable, and the remaining nodes determine which node will take ownership.
Disk array, английский
Дисковая матрица
Disk bit, английский
A roller-type rock bit with smooth-edged cutter disks instead of toothed or serrated cones. the term is seldom used, as the disk bit has been more or less replaced by serrated-tooth roller-cone rock bits.
Disk block, английский
Дисковый блок
Disk block program list, английский
Распечатка управляющих программ (хранящихся) на магнитном диске (центральной эвм)
Disk bottleneck, английский
A condition that occurs when disk performance is reduced to the extent that overall system performance is affected.
Disk brake, английский

Discounting, английский
- Дисконтирование
- Discounting is a method for combining or de-emphasizing belief and probability functions, either by weighted averages of a set of functions or combining a single function with a vague or vacuous function. as an example of the latter, a belief function could be averaged with a belief function that assigns all of its mass to the entire frame of discernment. it can also be used to combine multiple experts belief functions that conflict with each other, unlike dempster`s rule of combination, which discards the probability mass assigned to conflicting subsets of the frame. see also: dempster`s rule of combination, frame of discernment.
- Calculating the present value of a future amount. discounting is opposite to compounding.
- A mathematical operation making monetary (or other) amounts received or expended at different points in time (years) comparable across time (see annex ii). the operator uses a fi xed or possibly time-varying discount rate (>) from year to year that makes future value worth less today. a descriptive discounting approach accepts the discount rates that people (savers and investors) actually apply in their day-to-day decisions (private discount rate). in a prescriptive (ethical or normative) discounting approach, the discount rate is fi xed from a social perspective, for example, based on an ethical judgement about the interests of future generations (social discount rate). in this report, potentials of renewable energy supplies are assessed using discount rates of , and %. dispatch (power dispatching / dispatchable): electrical power systems that consist of many power supply units and grids are governed by system operators. they allow generators to supply power to the system for balancing demand and supply in a reliable and economical way. generation units are fully dispatchable when they can be loaded from zero to their nameplate capacity without signifi cant delay. not fully dispatchable are variable renewable sources that depend on natural currents, but also large-scale thermal plants with shallow ramping rates in changing their output. see also balancing, capacity, grid. district heating (dh): hot water (steam in old systems) is distributed from central stations to buildings and industries in a densely occupied area (a district, a city or an industrialized area). the insulated two-pipe network functions like a water-based central heating system in a building. the central heat sources can be waste heat recovery from industrial processes, waste incineration plants, geothermal sources, cogeneration power plants or stand-alone boilers burning fossil fuels or biomass. more and more dh systems also provide cooling via cold water or slurries (district heating and cooling - dhc).
Disk partition, английский
- Дисковый раздел; раздел диска
- A section of space on a physical disk that functions as if it were a separate disk.
