In computer graphics, any point of a device that can be addressed.
Industry:Telecommunications
In computer graphics, an image created with, or represented by, a matrix of pixels. Synonym raster graphics.
Industry:Telecommunications
In computer graphics, a representation of an image (which category includes characters) by code or a coding scheme that defines (a) the position of pixels by row (horizontal position) and column (vertical position,) and (b) individual pixel characteristics such as gray scale and color. Loosely synonymous with raster.
Industry:Telecommunications
In computer and communications systems operations, pertaining to a power-saving condition or status of operation of equipment that is ready for use but not in use. Note: An example of a standby condition is a radio station operating condition in which the operator can receive but is not transmitting. 2. Pertaining to a dormant operating condition or state of a system or equipment that permits complete resumption of operation in a stable state within a short time. 3. Pertaining to spare equipment that is placed in operation only when other, in-use equipment becomes inoperative. Note: Standby equipment is usually classified as (a) hot standby equipment, which is warmed up, i.e., powered and ready for immediate service, and which may be switched into service automatically upon detection of a failure in the regular equipment, or (b) cold standby equipment, which is turned off or not connected to a primary power source, and which must be placed into service manually.
Industry:Telecommunications
In computer graphics, a lever (with at least two degrees of freedom) that is used as an input unit, normally as a locator.
Industry:Telecommunications
In computer graphics, a device that sequentially samples and records digitally the color and intensity of successive elements of an object or image (e. G. , a flat, paper object such as a photograph or drawing,) for digital storage, transmission, or processing. Note: The collected data are usually stored in one of several computer graphics formats. 2. In television technology, a device that (a) scans successive frames (images) on motion-picture film, and (b) transcodes the digital data so obtained into an electronic signal (e. G. , analog NTSC signal, or other signal, including a digital signal) that conforms to any standard or accepted video format. Note: Scanners may also scan video images in non-real-time transcoding. The scanner may provide input to a recorder, to a signal processor, to a transmission channel, or to any other desired peripheral system. 3. In computer (specifically, word-processing) technology, a device that examines text, e. G. , on a printed page, and applies certain character-recognition algorithms or principles to determine the text elements (letters, numerals, and other characters) in sequence and convert them into standard (e. G. , ASCII) digital code for storage or further processing. Note: This special application of character-recognition technology eliminates laborious manual transcription of text, by keyboard entry, into digital files. 4. A device that examines a spatial pattern, one part after another, and generates analog or digital signals corresponding to the pattern. Note: Scanners are often used in mark sensing, pattern recognition, and character recognition. 5. A radio receiver that is automatically and rapidly tuned (i.e., sweeps) across a predetermined range of frequencies (band,) locking onto any frequency at which a signal is detected. Note: A scanner provides a means of monitoring a range of frequencies, and any traffic that may be present, but will usually not permit the simultaneous monitoring of more than one frequency.
Industry:Telecommunications
In computer graphics and in telecommunications, a permanent reproduction, on any media suitable for direct use by a person, of displayed or transmitted data. Note 1: Examples of hard copy include teletypewriter pages, continuous printed tapes, facsimile pages, computer printouts, and radiophoto prints. Note 2: Magnetic tapes, diskettes, and nonprinted punched paper tapes are not hard copy.
Industry:Telecommunications
In computer display, a line of alphanumeric characters that scrolls through, and within, a defined area (window. ) 2. An HTML tag that enables the display of a marquee.
Industry:Telecommunications
In computer conferencing, to add one's address to a distribution list, or to join a forum.
Industry:Telecommunications
In computer conferencing, a person who receives the prospective messages from conference attendees and may accept, modify, or reject them. Synonym conference controller.
