A kibibyte (KiB) is a unit of digital information storage that equals 1,024 bytes. It is part of the binary system, which is commonly used in computing. The term was introduced to provide a clear distinction between binary and decimal measurements of data, as the prefix "kilo" in the decimal system typically refers to 1,000. The use of kibibytes is important in contexts like computer memory and file sizes, where precision is necessary. It is part of a larger set of binary prefixes, including mebibyte (MiB) and gibibyte (GiB), which help standardize measurements in computing and avoid confusion with their decimal counterparts.
