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 largest value of byte is 2X2X2X2X2X2X2X2=256, and to represent bigger numbers, we need to use KB. Next comes KB which is 2X2X2X2X2X2X2X2X2X2=1024 bytes. This is also referred to as 1000 bytes in the metric system. Clearly binary KB is bigger than decimal KB. MB is 2 multiplied 20 times or 1048576 bytes.
