nanosecondenUKnanosecond[′nan·ə‚sek·ənd]nanosecond(unit)This is the unit in which the fundamental logical operationsof modern digital circuits are typically measured. Forexample, a microprocessor with a clock frequency of 100megahertz will have a 10 nanosecond clock period. nanosecond(1) One billionth of a second. Used to measure the speed of logic and memory chips, a nanosecond can be visualized by converting it to distance. In one nanosecond, electricity travels approximately a foot in a wire. Admiral Grace Hopper was famous for handing out strands of "telephone wire nanoseconds" to her audience whenever she lectured about technology. Holding the wire turns the unreal concept of a billionth of a second into reality.Even at 186,000 miles per second, electricity is never fast enough for the hardware designer who worries over a few inches of circuit path. The slightest delay is multiplied millions of times, since billions of pulses are sent through a wire in a single second. In addition, today's chips contain more than a thousand feet of wire traces, which are the circuit pathways that carry electricity. See space/time, jiffy and ohnosecond. (2) The time between a traffic light turning green and a New York City cab driver blowing his horn. nanosecondenUKnanosecond(ns) [nan´o-sek″ond]nan·o·sec·ond(nan'ō-sek-ŏnd)nanosecondOne billionth of a second.See NEXTSTEP nanosecondenUK
