A kibibyte (a contraction of kilo binary byte) is a unit of information or computer storage, established by the International Electrotechnical Commission in 2000. A bit is a binary digit, taking a value of either 0 or 1 Binary digits are a basic unit of Information storage and communication A byte (pronounced "bite" baɪt is the basic unit of measurement of information storage in Computer science.

1 kibibyte = 210 bytes = 1,024 bytes

The kibibyte is closely related to the kilobyte, which can be used either as a synonym for kibibyte or to refer to 103 bytes = 1,000 bytes (see binary prefix). A byte (pronounced "bite" baɪt is the basic unit of measurement of information storage in Computer science. A kilobyte (derived from the SI prefix Kilo -, meaning 1000 is a unit of Information or Computer storage equal to either 1024 In computing binary prefixes are names or associated symbols that can precede a unit of measure (such as a Byte) to indicate multiplication by a power of two

Usage of these terms is intended to avoid the confusion, common in describing storage media, as to the ambiguous meaning of "kilobyte". Thus the term kibibyte has evolved to refer exclusively to 1,024 bytes. A byte (pronounced "bite" baɪt is the basic unit of measurement of information storage in Computer science.

The confusion if kilobyte is used to refer to both 1,000 and 1,024 bytes became more substantial when hard drives grew to gigabyte and larger units. A hard disk drive ( HDD) commonly referred to as a hard drive, hard disk, or fixed disk drive, is a Non-volatile storage device A gigabyte (derived from the SI prefix Giga-) is a unit of Information or Computer If one expects power-of-two values to refer to capacity, and manufacturers use power-of-ten values, the difference could be substantial. With a kilobyte (1,024 versus 1,000), the difference is 2. 4%. With the megabyte (1,024² or 1,048,576, versus 1,000,000) the percentage difference becomes 4. 9%. With "gigabytes", if one uses 1024³, the size of a drive would be expected to be 1,073,741,824 bytes per gigabyte versus a mere 1,000,000,000 - a difference of 7. 4%.

Confusion can be compounded by the use of both 1,024 and 1,000 in a single definition. The quoted capacity of 3½ inch HD floppy disks is 1. 44 MB, where MB stands for 1000 times 1024 bytes. The total capacity is thus 1,474,560 bytes, or approximately 1. 41 MiB.

## Adoption

Adoption of this term has been limited, because in the most common applications (e. g. , displaying file sizes, download speeds) typical values are not multiples of large powers of two, and therefore use of the decimal prefix "kilo" is more convenient. [2][3][4][5]
