Kibibyte

The kibibyte is a multiple of the unit byte for quantities of digital information. The binary prefix kibi, a contraction of "kilo-, binary ," denotes the base-ten number 1024, the binary number closest to 1000; therefore, 1 kibibyte is 1024bytes. The unit symbol for the kibibyte is KiB. The unit was established by the International Electrotechnical Commission (IEC) in 1999 and has been accepted for use by all major standards organizations. It was designed to provide an alternative to the use (according to SI standards, the misuse) of the term "kilobyte" to denote a data quantity of 1024 bytes, but it has seen little adoption by the computer industry.
