Size of files in Windows OS. (It's KB or kB?) One kilobyte (KB) is 1024 bytes in JEDEC-standard, whereas the definition has shifted, in most contexts, to mean 1000 bytes (kB) in accordance with SI. To resolve this difference, binary prefixes (kiB) are used. So we have 3 choices for using prefixes - JEDEC, IEC (both in Binary), and Metric (in Decimal).
The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix kilo as 1000 (103); therefore one kilobyte is 1000 bytes. The unit symbol for the kilobyte is kB. In information technology, particularly in reference to main memory capacity, kilobyte is traditionally used to denote 1024 (210) bytes.
