技嘉或技嘉(1000或1024)? [英] Gigabyte or Gibibyte (1000 or 1024)?

问题描述

这可能是重复的，如果是这样的话，我深表歉意，但是我真的想要一个确定的答案，因为这个答案似乎会根据我的位置而改变.

This may be a duplicate and I apologies if that is so but I really want a definitive answer as that seems to change depending upon where I look.

可以说一个千兆字节是1024兆字节还是应该说它是1000兆字节?我在GCSE上攻读计算机科学，一个典型的考试问题可能是千字节中有多少个字节，我相信AQA考试委员会的答案是1024，而不是1000.这是什么?都正确吗?我应该去哪一个?

Is it acceptable to say that a gigabyte is 1024 megabytes or should it be said that it is 1000 megabytes? I am taking computer science at GCSE and a typical exam question could be how many bytes in a kilobyte and I believe the exam board, AQA, has the answer for such a question as 1024 not 1000. How is this? Are both correct? Which one should I go with?

预先感谢-这让我颇为震惊！

Thanks in advance- this has got me rather bamboozled!

推荐答案

可悲的事实是，这取决于您问的是谁.但是计算机术语正逐渐与常规术语保持一致，其中公斤为10 ³ (1,000)，兆字节为10 ⁶ (1,000,000)，千兆字节为10 ⁹ (1,000,000,000).

The sad fact is that it depends on who you ask. But computer terminology is slowly being aligned with normal terminology, in which kilo is 10³ (1,000), mega is 10⁶ (1,000,000), and giga is 10⁹ (1,000,000,000).

这反映在国际数量系统和国际电工委员会中，它们定义了技嘉为10 ⁹ 并使用

This is reflected in the International System of Quantities and the International Electrotechnical Commission, which define gigabyte as 10⁹ and use gibibyte for the computer-specific 1024 x 1024 x 1024 value.

它取决于您询问的人"的原因是很多年，特别是与存储的字节"有关，前缀千，兆和千兆字节表示1024、1024 ² 和1024 ³ .但是，就这些前缀而言，这违背了常规惯例.再次重申，计算机术语与非计算机术语是一致的.

The reason it "depends who you ask," is that for many years, specifically in relation to "bytes" of storage, the prefixes kilo, mega, and giga meant 1024, 1024², and 1024³. But that flies in the face of normal convention with regard to these prefixes. So again, computer terminology is being aligned with non-computer terminology.
