Gigabyte

Nach ISO 10000 steht die Vorsilbe "Giga" für 10 hoch 12. Demnach ist z.B. 1 Gigabyte = 1000 Megabyte.

In der IT wird dageegen gerne definiert: "1 Gigabyte = 1024 Megabyte", dies ist aber inkorrekt.

Noch nicht sehr vebreitet ist die Normung solcher "binären Vorsilben" durch die IEC: Gibibyte (GiB).

In December 1998, the IEC produced new prefixes for binary multiples: kibibytes (KiB), mebibytes (MiB), gibibytes (GiB), tebibytes (TiB), and so on. (More details at NIST, also released as IEEE Std 1541-2002) These prefixes may never catch on, or they may cause even more confusion, but they are a valiant effort to solve the problem. The big strike against them is that they sound rather silly.
