How many bytes are in a gaga byte?

A gigabyte (often abbreviated as GB) is commonly understood to be 1,073,741,824 bytes, which is 2^30 bytes in binary computing. However, in the context of storage devices and some definitions, it may also be considered as 1,000,000,000 bytes (10^9) in decimal. The term "gaga byte" seems to be a typographical error or a play on Words, as there is no standard unit by that name in computing.
