    • The gigabyte (or [1] ) is a multiple of the unit byte for digital information.

      The prefix giga means 109 in the International System of Units (SI), therefore one gigabyte is . The unit symbol for the gigabyte is GB.

      This definition is used in all contexts of science, engineering, business, and many areas of computing. However, historically, the term has also been used in some fields of computer science and information technology to denote the gibibyte, or (10243 or 230) bytes. For instance, the memory standards of JEDEC, a semiconductor trade and engineering society, define memory sizes in this way.

      To eliminate the ambiguity, the International Electrotechnical Commission has implemented the binary prefixes, a standard of multiplier prefixes for quantities expressed in binary multiples. The standard is endorsed by all standards organizations, including the IEEE, the International Committee for Weights and Measures (CIPM) and the U.S. National Institute of Standards and Technology (NIST), but the binary prefixes have seen limited usage. While the JEDEC industry consortium has endorsed the binary prefixes, it continues to permit the IEEE 100 nomenclature of using the metric prefixes kilo, mega and giga in their binary interpretation for memory manufacturing designations.
