giga-

giga- (symbol: G) A prefix indicating a multiple of one billion, 109, as in gigahertz and gigavolt. When the binary number system is used in a structure or process (as in semiconductor RAM or ROM) the prefix then indicates a multiple of 230, i.e. 1 073 741 824,

as in gigabyte and gigabit. The context usually clarifies which meaning is intended, although, being quite close numerically, the meanings are often considered more or less equivalent.
