Cd-rom compact disc - read only memory
| Telecommunications Glossary |
Cd-rom discs can store a variety of data types including text, color graphics, sound, animation and digitized video that can be accessed and read through a computer. a disc can store up to 600 megabytes of data, much more information that can be stored on a 3.5 inch compute disk, which hold up to 1.4 megabytes. this makes cd-rom an inexpensive medium for storing large amounts of data. because cd-rom was not designed to store digitized, full-motion video, compression technology is important in compressing data to fit on a disc as well as decompressing data for playback.

Information, английский
- Knowledge of a particular event or situation, or knowledge communicated or received concerning a particular fact.
- Информация
- Facts about something have you any information about the treatment of sunburn? the police won’t give us any information about how the accident happened. you haven’t given me enough information about when your symptoms started. that’s a very useful piece or bit of information. (note: no plural: some information; a piece of information.)
- N информация | attr. информационный flow, structure source of ~ источник информации 1 ранее использовался в более широком значении как ‘умозаключе- ние’. 2 получение выводных данных в процессе обработки информации и/или языка и само выводное знание, умозаключение; мыслительная операция, в ходе которой человек выходит за пределы данных в тек- сте сведений и получает новую информацию. 3 аффикс, вставляемый внутрь корня слова при словообразовании или словоизменении.
- In admiralty courts, implies a clause introduced into a citation, intimating that in the event of a party cited not appearing, the court will proceed in his absence.
- Информация; данные; сведения
- Координационный комитет ин4юрмации о проектируемых и возводимых объектах строительства
- Literally that which forms within, but more adequately
- Data that has been recorded, classified, organized, related or interpreted so that meaning is apparent.
- Contextualised data providing answer to a certain question decreasing uncertainty.
- Информация, сведения
Compression, английский
- A state or condition of being pushed or shortened by a force.
- Сжатие
- Сжатие (данных), уменьшение размеров файла изображения. см. также lossy и non-lossy. процесс упаковки данных с целью уменьшения занимаемого ими пространства на накопителе
- Компрессия, сжатие
- The reduction of volume of a vapor or gas by mechanical means.
- Digital video pictures can be compressed with a number of techniques. these include: jpeg and jpeg-2000 (for still images), m-jpeg and mpeg (for moving pictures).
- The reduction in gain at one level of a picture signal with respect to the gain at another level of the same signal.
- A digital photograph creates an image file that is huge, a low-resolution 640x480 image has 307,200 pixels. if each pixel uses 24 bits (3 bytes) for true color, a single image takes up about a megabyte of storage space. to make image files smaller almost every digital camera uses some form of compression. see the jpg entry below.
- The application of any of several techniques that reduce the amount of information required to represent that information in data transmission. this method reduces the required bandwidth and/or memory.
- A method of reducing the size of a digital image file to free up the storage capacity of memory cards and hard drives. compression technologies are distinguished from one another by whether or not they remove detail and color from the image. lossless technologies compress image data without removing detail, while "lossy" technologies compress images by removing some detail. joint photographic experts group (jpeg) is a lossy compression format supported by jpeg, pdf and postscript language file formats. most video formats are also lossy formats. tiff files are not and, as such, are far more stable than jpegs and other lossy file formats.
- Reducing the number of bits needed to encode a digital signal, typically by eliminating long strings of identical bits or bits that do not change in successive sampling intervals (e.g., video frames).
- A digital photograph creates an image file that is enormous. to enable image files to become smaller and more manageable cameras employ some form of compression such as jpeg. raw and tiff files have no compression and take up more space.
- 1. the act of squeezing or pressing the first-aider applied compression to the chest of the casualty. 2. a serious condition in which the brain is compressed by blood or cerebrospinal fluid accumulating in it or by a fractured skull
- Смыкание (губок захватного устройства) cm. соmрutеr-соntrоllеd rоbоt 33. соntinuоus-раth mоtiоn движение робота по полностью программируемой траектории (при котором полная траектория, описываемая рукой манипулятора, программируется на программоноситель во время обучения так, чтобы каждая точка вдоль траектории движения регистрировалась для дальнейшего воспроизведения)
- Сжатие (данных); уплотнение; свертка; компрессия; упаковка
- Жёсткость (стержня) при сжатии; ~ in tension жёсткость (стержня) при растяжении; ~ in
- Продольно-поперечный изгиб, поперечный изгиб со сжатием; ~ and axial tension изгиб с осевым растяжением; ~ in two planes косой изгиб ~ of rebars [of reinforcing bars] гибка арматурных стержней beam ~ изгиб балки
- Сжатие о ~ along the grain сжатие вдоль волокон; ~ beyond
- Сжатое волокно; ~ in
- The intentional reduction in dynamic range to increase sustain and/or add punchiness, caused by a the use of a compressor/limiter.
- A process for removing redundant data from a digital media file or stream to reduce its size or the bandwidth used.
- A reduction of the time available for a scheduled storyboard to reach its final state.
- A way of making files smaller, either to fit into restricted storage space or to speed up transmission over the internet. popular compression standards include- jpeg- and- gif- for pictures,- mp3for music files,- mpeg, mp4, avi- and- mov- for movie footage, and- zip- for just about everything else.
Technology, английский
- The use of tools and knowledge to meet human needs.
- Техника; технология
- Техника (означает все знания или неотъемлемую часть знаний о: научных принципах или открытиях; промышленных процессах; материальных и энергетических ресурсах; средствах транспорта и связи, постольку, поскольку эти знания непосредственно касаются развития производства товаров или сферы услуг; документы юнеско)
- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).

Cd-rom drive, английский
- A computer peripheral that plays cd-roms.
- An electromechancial device that reads data on cd-roms. most cd-rom drives have a scsi interface, although some are connected to a pc via a controller for a disk drive. data is read through a small laser that is focused on the surface of the cd-rom through optical mirrors in the read/write head. a spindle and drive motor revolve the cd-rom, so all data, which is stored in spirals from the center, can be read.
Cd-i, английский
1. compact disc-interactive. stores text, audio, video, images and animation. requires a player and will not work on a regular cd-rom player. 2. this interactive multimedia system, developed by philips and sony, connects to a television and stereo audio system. the standards for this are called the green book.
