Double-density disk
| Глоссарий ИТ-терминов |
A disk created to hold data at twice the density (bits per inch) of a previous generation of disks. early ibm pc floppy disks held 180 kb of data. doubledensity disks increased that capacity to 360 kb. double-density disks use modified frequency modulation encoding for storing data.

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).
- Диск

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
Generation, немецкий
Modulation, английский
- Изменение характеристик несущей в соответствии с информативным сигналом
- Модуляция
- The process, or results of the process, whereby some characteristic of one signal is varied in accordance with another signal. the modulated signal is called the carrier. the carrier may be modulated in three fundamental ways: by varying the amplitude, called amplitude modulation; by varying the frequency, called frequency modulation; by varying the phase, called phase modulation.
- The process by which some characteristic (i.e., amplitude, phase) of one rf wave is
- The process by which some characteristic (i.e., amplitude, phase) of one rf wave is varied in accordance with another wave (message signal).
- The coding of information onto a carrier frequency. may use amplitude, frequency, phase, or time, plus many forms of on/off digital coding
- The ability to superimpose an external signal on the output beam of the laser as a control.
- The process by which the characteristic of one wave (the carrier) modifies another wave (the signal). examples include amplitude modulation (am), frequency modulation (fm), and pulse-coded modulation (pcm).

Symbolic link, английский
A disk directory entry that takes the place of a directory entry for a file but is actually a reference to a file in a different directory.
