* January: Bruce Barrow endorses the [[International Union of Pure and Applied Chemistry]]'s proposal for prefixes {{brown|kibi}}, {{brown|mebi}}, {{brown|gibi}}, etc.and {{brown|tebi}} in "A Lesson in Megabytes" in IEEE Standards Bearer,<ref>Bruce Barrow, A Lesson in Megabytes, IEEE Standards Bearer 11, 5, January 1997</ref><ref>{{cite web|title=A Lesson in Megabytes|url=https://www.thierry-lequeu.fr/data/PELS/Comm/Publications/Newsletter/9704/STORY18.HTML|website=La documentation de Thierry LEQUEU}}</ref> but instead using the symbols {{brown|Ki}}, {{brown|Mi}}, {{brown|Gi}}, and {{brown|Ti}}.
* IEEE requires prefixes to take the standard SI meaning (e.g., {{blue|mega}} always to mean 1000<sup>2</sup>). Exceptions for binary meaning ({{brown|mega}} to mean 1024<sup>2</sup>) are permitted as an interim measure (where pointed out on a case-by-case basis) until a binary prefix could be standardised.<ref>{{cite web |title=IEC prefixes and symbols for binary multiples |website=Members.optus.net |url=http://members.optus.net/alexey/prefBin.xhtml |access-date=2016-06-23 |archive-url=https://web.archive.org/web/20161207182048/http://members.optus.net/alexey/prefBin.xhtml |archive-date=2016-12-07 |url-status=dead}}</ref>
