A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two. The most commonly used binary prefixes are kibi (symbol Ki, meaning 2 10 = 1024), mebi (Mi, 2 20 = 1 048 576), and gibi (Gi, 2 30 = 1 073 741 824).

Ki 是Kilo binary（千位二进制）的缩写，其中 K 表示kilo（千）， i 是binary（二进制）的缩写，表示Ki是计算机领域（二进制）的计数单位“千”，旨在与普通行业领域（十进制）的计数单位k（kilo：千）进行区分。 Mi （兆/百万）、 Gi （吉/十亿）的定义与之类似： 在表示数据存储量时，默认就用 B（字节）作为最小的计量单位，配合以上计数单位来表示，如： 例如使用FTP工具 FileZilla 下载数据时，可看到下载速度：MiB/秒，就表示每秒下载多少兆字节的数据，如图所 …

名字的前两个字母来源于原来的国际单位制词头（例如， kilo binary byte縮寫為「kibi-Byte」、「kiB」、「kibi-byte」），而后面的「bi」是二进制的缩写。同时明确定义，从IEC的观点来看，国际单位制词头只有十进制的意义而不再用作二进制的意义。

Under the IEC 60027-2 A.2 and ISO/IEC 80000 standards, the correct notation of 230 is gibi (symbol Gi). So, 1 GiB is 1,073,741,824 bytes or 1.074 GB. Despite international standards, the use of 1 GB = 2^30 B is widespread. A laptop advertised as having 8 GB has 8,589,934,592 bytes of memory: 8.59×109 B, or 8 GiB.

2019年8月26日 · Gibibyte(giga binary byte的缩写)是信息或计算机硬盘存储的一个单位，简称GiB。由来“GiB”、“KiB”、“MiB”等是于1999年由国际电工协会(IEC)拟定了"KiB"、“MiB”、“GiB"的二进制单位，专用来标示“1024进位”的数据大小。而后，这一标注规范又于2008年并入国际标准化 ...

A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method for representing numbers that uses only two symbols for the natural numbers: typically "0" and "1" .

二进制（binary），是在数学和数字电路中以2为基数的记数系统，是以2为基数代表系统的二进位制。 这一系统中，通常用两个不同的符号0（代表零）和1（代表一）来表示。

Kibi, mebi, gibi, tebi, pebi and exbi are binary prefix multipliers that, in 1998, were approved as a standard by the International Electrotechnical Commission (IEC). This was done in an effort to eliminate the confusion that sometimes occurs between decimal (power of 10) and binary (power of 2) numeration terms.

2025年2月11日 · Binary is a numerical system that uses only two digits, 0 and 1, to represent values, often in a computing system. You’ll sometimes see binary referred to as a base-2 system. Binary differs from the decimal system that we use every day, which uses ten digits (0 - 9) to represent values — also called the base-10 number system.

2021年1月6日 · Hệ thống số nhị phân, trong toán học, hệ thống số vị trí sử dụng 2 làm cơ số, do đó chỉ yêu cầu hai ký hiệu khác nhau cho các chữ số của nó, 0 và 1, thay vì 10 ký hiệu khác nhau thông thường cần thiết trong hệ số thập phân. Do đó, các số từ 0 đến 10 ở dạng nhị phân 0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001 và 1010.
