The Kibibyte
A kibibyte (KiB) is a unit of information equal to exactly 1,024 bytes.
A kibibyte is therefore equal to exactly 8,192 bits.
The use of the kibibyte is that by convention, a kilobyte is supposed to be equal to 1,000 bytes, but is sometimes used by manufacturers of computer parts to mean 1,024 bytes.
Some computer storage/RAM manufactures use base 10 (where a kilobyte is equal to 1,000 bytes) when defining their memory capacity, while some computer storage/RAM manufacturers use base 2 (where a kilobyte is equal to 1,024 bytes) when defining their memory capacity, which can lead to confusion.
So the kibibyte, being exactly equal to 1,024 bytes in all contexts, helps to remove ambiguity in measurements.
