Note: the term "gibibit" is a theoretical word based on constructions found in the IEC binary prefix naming scheme. Though intended to be morphologically parallel to "gibibyte" the word "gibibit" has no known practical application.[1]
A gibibit (a contraction of giga binary binary digit) is a proposed unit of data or computer storage, which can be abbreviated as Gibit or Gib.
- ^ As bits have traditionally been expressed using base-10 (to express data transfer rates), not base-2, a linguistic parallel to gibibyte is not needed (i.e. there is no established need to express 230 bits, only 230 bytes). Reference example: http://www.webopedia.com/TERM/M/Megabyte.html)
