An exabyte (derived from the SI Prefix '' Exa ''-, and abbreviated as '''EB''') is a unit of Information or Computer Storage equal to approximately one Quintillion Byte s. Because of irregularities in the definition and usage of terms for byte multiples, the exact number can be either one of the following:
Because of these irregularities, the term " Exbibyte " has been proposed as an unambiguous reference to the latter value. (See Binary Prefix es.) As Of 2005 , exabytes of data are almost never encountered in any practical context. For example, the total amount of printed material in the world is estimated to be around five exabytes. However, one may hear of 16 or 18 exabytes of Address Space when discussing 64-bit architectures. It was estimated that by the end of 1999, the sum of human knowledge (including audio, video and text) was 12 exabytes. {Link without Title} Research at the UC Berkeley School of Information suggests that 5 exabytes of new information was created in 2002 alone, 92% of it on magnetic media, mostly on hard discs. {Link without Title} SEE ALSO EXTERNAL LINKS AND REFERENCES |
