Yobibyte

The yobibyte is a multiple of the unit byte for digital information. It is a member of the set of units with binary prefixes defined by the International Electrotechnical Commission (IEC). Its unit symbol is YiB

The prefix yobi (symbol Yi) represents multiplication by 1024⁸, therefore:

1 yobibyte = 2⁸⁰ bytes = 1208925819614629174706176bytes = 1024 zebibytes

The prefixes zebi and yobi were originally not part of the system of binary prefixes, but were added by the IEC in August 2005.^[1]
