What is a kilobyte?

The kilobyte, in the decimal SI sense, is 1,000 bytes. A short plain-text email weighs a few kB. Some software still uses KB to mean 1,024 bytes; the precise name for that is the kibibyte, KiB.

What is a kibibyte?

The kibibyte is 1,024 bytes, or 2¹⁰. The IEC introduced the binary prefixes kibi, mebi, gibi and tebi in 1998 to end the confusion between 1,000 and 1,024. Memory page sizes, such as 4 KiB, are naturally binary.
