Prefixes to denote the byte being based on 1024 rather than 1000 were also created, with gibibyte referencing 1024 3 bytes. Because this can be the source of confusion, in 1998, the International Electrotechnical Commission published standards that required the gigabyte strictly denote 1000 3 bytes. There is also however, a binary definition where a gigabyte is 1024 3 bytes. The gigabyte is most commonly understood in terms of its decimal definition of 1000 3 bytes.
History/origin: The gigabyte is based on the byte, which is derived from the bit, and is a unit that makes use of SI (International System of Units) prefixes. Definition: A gigabyte (symbol: GB) is equal to 10 9 bytes (1000 3 bytes), where a byte is a unit of digital information that consists of eight bits (binary digits).
