    why kbyte=2^10 ??

    a byte=2^8

    kilo=1000

    2^8 * 1000 differs 2^10

    ??

    Someone decided that for binary based computer usage, it would be better to state everything values close to powers of 2. Since 2^10 is 1024, and close to 1000, it became "kilo". Similarly 2^20 is "mega", 2^30 is "giga", and 2^40 is "tera".

    The International Electrotechnical Commission has tried to resolve this confusion by defining a new set of binary-based prefixes, e.g. 1 kibibyte = 1024 bytes.

    See this Wikipedia article for more details.

    Personally, I think "kibibyte" sounds like a brand of dog food. :rolleyes:

    which have been almost universally ignored.
