Template talk:Bit and byte prefixes

"Note that the IEC names are defined only up to exbi-, corresponding to the SI prefix exa-. The two SI prefixes zetta- (1021) and yotta- (1024) have no corresponding IEC binary prefixes, though the obvious continuation would be zebi- (Zi = 270 = 10007 × 1.180 591 620 717 411 303 424) and yobi- (Yi = 280 = 10008 × 1.208 925 819 614 629 174 706 176)."

This standard was developed specifically to meet industry’s needs in data processing and data transmission. It eliminates confusion by setting out the prefixes and symbols for the binary, as opposed to decimal, multiples that most often apply in these fields. Zebi and yobi are the latest in this evolution. The term zebi means “two to the power 70”. The term yobi means “two to the power 80”. [1]
