定义
二进制前缀（KiB、MiB、GiB）表示1024的幂，与SI公制前缀（KB、MB、GB）表示1000的幂形成对比。
解释
1 KiB (kibibyte) = 1,024 bytes; 1 KB (kilobyte) = 1,000 bytes. The gap widens at higher scales: 1 GiB = 1,073,741,824 bytes vs. 1 GB = 1,000,000,000 bytes—a 7.4% difference. This explains why a '1 TB' hard drive shows as ~931 GiB in an OS. The IEC standardized the binary prefixes in 1998 specifically to resolve this ambiguity.
