Zebra Pattern (A/V)
In audio/visual production, a pattern of zebra-like stripes that are superimposed over a camera viewfinder image area that are at or near 101 IRE units, as an aid to exposure (depending on the specific design and manufacturer of the camera).
Zener Diode (computer/microelectronics)
P-N junction two-terminal, single junction semiconductor device reverse biased into the breakdown region and providing high impedances under less than breakdown voltage, but conduction with no impedance above breakdown voltage level. The device is used principally in voltage regulator circuits to provide a voltage reference.
Zero: "0" (computer)
False statement, off connotation, negative connotation, opposite of "1", logic statement.
Zero Wait State (computer)
Microprocessor memory condition and feature of high-speed memory access and transfer, whereby there are no delays (wait-states) in transferring information within the system.
Z-Modem (communications, computer)
Asynchronous communications protocol that offers extended error protection over X-Modems, and that can handle large file transfers even with some transmission delays.
Z-Motion (computer, microelectronics)
In microelectronics fabrication, the vertical adjustment of screen-substrate distance: used for setting snap-off and levelling in screen printing.
