* Using SI, one exabyte is equivalent to 1,000 petabytes or 1,000,000,000,000,000,000 bytes.
* Using traditional binary measurement, one exabyte is equivalent to 1,152,921,504,606,846,976 bytes, that’s 260 bytes, also equivalent to 1 exbibyte.The prefix "exa" is part of the International System of Units (SI), and means 1018 units. Hard disk manufacturers label their products in SI units, which may confuse some people in the IT field. The International Organization for Standardization (ISO), Institute of Electrical and Electronics Engineers (IEEE) and International Electrotechnical Commission (IEC) all recommend using the exbibyte (EiB) unit, which signifies 260 bytes and is more accurate for the measure of bytes.<br />Two interpretations can be made using the two standards:<br />
** Using SI, one exabyte is equivalent to 1,000 petabytes or 1,000,000,000,000,000,000 bytes.
** Using traditional binary measurement, one exabyte is equivalent to 1,152,921,504,606,846,976 bytes, that’s 260 bytes, also equivalent to 1 exbibyte. <br />
Cisco Systems was out last week with its annual “Visual Networking Index Forecast,” or “VNI,” which aims to put some numbers on the mind-bending enormity of Internet traffic.
The full report goes off in all kinds of interesting directions. This week’s translation walks through some of the language of what’s quickly becoming the even bigger Very Big Numbers of the Internet.
'''WHAT’S AN EXABYTE?'''
Let’s start with the “Exabyte,” abbreviated “EB,” because that’s where we’re headed between now and 2014. An Exabyte is one quintillion bytes. It’s a one, with 18 zeros behind it.
According to the VNI Forecast, Internet traffic around the globe will reach nearly 64 exabytes per month in 2014. That’s equivalent to 11.8 billion DVDs, 15.8 trillion MP3 files, or 295 quadrillion text messages.
In the hierarchy of numbers, the Exabyte comes after the Petabyte, but before the Zettabyte. (That’s right. Zettabyte. Although “Zappabyte” seems just as effective.)
So: A Gigabyte (GB) is 1,000 Megabytes (MB); a Terabyte (TB) is 1,000 Gigabytes; a Petabyte (PB) is 1,000 Gigabytes; an Exabyte (EB) is 1,000 Petabytes, and a Zettabyte (ZB) is 1,000 Petabytes. And yes, there’s one more after that - the “Yottabyte (YB).” You guessed it: 1,000 Zettabytes. (Which gives new oomph to “yotta, yotta, yotta.”)
