What Is A Nanosecond, And Why Do We Need To Understand That?

By: Bruce G. Kreeger

From Wikipedia, the free encyclopedia

A¬†nanosecond¬†(ns) is an¬†S.I. unit¬†of time equal to one billionth of a¬†second, that is,¬†1‚ĀĄ1 000 000 000¬†of a second, or 10‚ąí9¬†seconds.

The term combines the prefix nano- with the basic unit for one-sixtieth of a minute.

A nanosecond is equal to 1000¬†picoseconds¬†or¬†1‚ĀĄ1000¬†microsecond. Time units ranging between 10‚ąí8¬†and 10‚ąí7¬†seconds are typically expressed as tens or hundreds of nanoseconds.

Time units of this granularity are commonly found in telecommunications, pulsed lasers, and related aspects of electronics.

To explain a nanosecond I am including a clip, below, of Admiral Grace Brewster Murray Hopper¬†(1906-1992), who was a computer pioneer and U.S. Navy Officer. She earned a master’s degree (1930) and a Ph.D. (1934) in mathematics from Yale.

Admiral Hopper is best known for her trailblazing contributions to computer programming, software development, and the design and implementation of programming languages. A maverick and an innovator, she enjoyed long and influential careers in the U.S. Navy and the computer industry. 

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. I was captivated.

At Clarity, we frequently hear a continued question of “why does it take so long” to retrieve data from the server, the internet, and my computer? While there are many contributing factors like malware, internet speed, network inefficiency, slow processor, or slow hard drive, often it is about the nanosecond.

At one point in time, I used to think higher speeds were attainable with higher degrees of bandwidth.¬†This may be why the idea of ‘low latency’ seems so counter-intuitive. As you hopefully understand at this point, there are limitations to how fast data can move and that real gains in this area can only be achieved through efficiency improvements, in other words, the elimination (as much as possible) of latency.

Ethernet, speed, and Internet speed, really are about latency.¬†Ethernet switch latency is defined as the time it takes for a switch to forward a packet from its ingress port to its egress port. The lower the latency, the faster the device can transmit packets to its final destination.¬†Also crucial within this “need for speed” is avoiding packet loss. The magic is within the balancing act: speed and accuracy that challenge our understanding of traditional physics.

The next time you wonder why it takes so long, remember it’s all about the network, latency, and the time (in nanoseconds) your data goes from point A to point B and back.

An example of the use of these measures is that if your CPU clock speed is 3.5 Mhz (Megahertz per Second)= 285.71428571429 ns(p) (ns=nanoseconds). Ipsofacto the higher the clock speed, the faster the computer is.

We are currently using the Picosecond (One trillionth of a second) as a unit of measure and the nanosecond.
