(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.
