The International Electrotechnical Commission has attempted to define (2) as the kilobyte and call (1) an kibibyte -- a term which however has not caught on. |
See integral data type. A gigabyte is 1024 times an megabyte. To clarify the meaning(1) above, the International Electrotechnical Commission (IEC), a standards body, in 1997 proposed short unions of the International System of Units (SI) prefixes with the word "binary." Thus meaning (1) would be called a mebibyte. This naming convention has not been widely accepted. links: http://www.quinion.com/words/turnsofphrase/tp-kib1.htm http://www.nist.gov/public_affairs/techbeat/tb9903.htm |
