Of a data medium such as a diskette, pertaining to the use of one or more schemes designed to thwart copying in violation of copyright law or security considerations.
Industry:Telecommunications
Of a device or network, a point of access where signals may be inserted or extracted, or where the device or network variables may be observed or measured. 2. In a communications network, a point at which signals can enter or leave the network en route to or from another network.
Industry:Telecommunications
Of a device, the capability to fail without detriment to other devices or danger to personnel. 2. Pertaining to the automatic protection of programs and/or processing systems to maintain safety when a hardware or software failure is detected in a system. 3. The automatic protection of programs and/or processing systems when hardware or software failure is detected. 4. Pertaining to the structuring of a system such that either it cannot fail to accomplish its assigned mission regardless of environmental factors or that the probability of such failure is extremely low.
Industry:Telecommunications
Of a device, the mathematical function that describes the output waveform that results when the input is excited by a unit impulse. 2. The waveform that results at the output of a device when the input is excited by a unit impulse.
Industry:Telecommunications
Of a directional antenna, the angle, in a vertical plane, subtended by the lines extending (a) from the antenna to the radio horizon and (b) from the antenna in its direction of maximum radiation.
Industry:Telecommunications
Of a fundamental frequency, the ratio of the power of a specified harmonic to the power of the fundamental frequency. Note: Single-harmonic distortion is measured at the output of a device under specified conditions and is expressed in dB.
Industry:Telecommunications
Of a material propagation medium, absorptance per unit path length.
Industry:Telecommunications
Of a monitor screen, the physical size (width) of an individual tristimulus optoelectronic element (e.g., phosphor triad, stripe triad, LCD element,) usually expressed in millimeters (e.g., "0. 28 mm dot pitch",) in the direction of scanning. Note: The width of one tristimulus optoelectronic element determines the maximum resolution of a monitor screen. 2. Of a dot-matrix printer, the maximum number of dots per inch that can be printed in the highest resolution setting.
Industry:Telecommunications
Of a network or device, the width of the continuous frequency range over which the phase-vs. -frequency characteristic does not depart from linearity by more than a stated amount.
Industry:Telecommunications
Of a network server, the maintenance of an identical copy of its files in (a) another network server, or (b) a redundant drive in the same server chassis. Note: Mirroring can be used as a rudimentary backup system for the original files, but is more often used to spread out the access load for popular sites, e.g., Web sites, by offering users several different locations from which identical files can be accessed. 2. Of a computer, the maintenance of an identical copy of its files in (a) another computer, or (b) another drive in the same computer chassis.
