Gigabyte
Nach ISO 1000:1992 steht die Vorsilbe "Giga" für das 10-hoch-12-fache einer Grundeinheit. Demnach ist z.B. 1 Gigabyte = 1000000000000 Byte.
In der IT wird dageegen gerne definiert: "1 Gigabyte = 1024 Megabyte", 1 MB = 1024 kB, aalso 1 GB = 2&ssup2;30 Byte 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.
