A storage unit where hard drive manufacturers define 1 KB = 1000 bytes, while operating systems traditionally treat it as 1024 bytes (now recommended to use KiB for 1024). Used for file sizes and memory capacity. Widely referred to as 'KB' in daily use in China, though confusion between decimal and binary interpretations persists.
