Every meter of cable length is about three nanoseconds -- the speed of a signal through copper, he said. Content Discovery initiative April 13 update: Related questions using a Review our technical responses for the 2023 Developer Survey. Memory speed is measured in Mega transfers per second (MT/s), whereas the latency is measured in nanoseconds. As the President of the Admiral Farragut Academy Alumni Association (Pine Beach, NJ) and a member of the Board of Trustees during my tenure, I had the honor of meeting Admiral Hopper and enjoying a meal with her. Until computer speeds reached gigahertz speeds, million instructions per second was a popular measure or rating for a computer. Latency is often misunderstood because on product flyers and spec comparisons, it's noted in CAS Latency (CL), which is only half of the latency equation. By definition of the "foot" as exactly 1/3 yards, and of the, International Bureau of Weights and Measures, https://en.wikipedia.org/w/index.php?title=Nanosecond&oldid=1115045544, 1.0 nanosecond cycle time of an electromagnetic wave with a, 10 nanoseconds cycle time for frequency 100MHz (1, 12 nanoseconds mean lifetime of a charged, 2040 nanoseconds time of fusion reaction in a, 77 nanoseconds a sixth (a 60th of a 60th of a 60th of a 60th of a second), This page was last edited on 9 October 2022, at 15:25. 1 day = 24 hours. You can use an online ram calculator in order to calculate the latency of your RAM. This compensation may impact how and where products appear on this site including, for example, the order in which they appear. Microtime always returns same values multiple? The number that is displayed therein should be expressed in clock cycles. Time units of this granularity are commonly found in telecommunications, pulsed lasers, and related aspects of electronics .
