Size, in computer terms, uses idiosyncratic units in addition to the bit and byte. Outside the world of computing, the prefixes kilo, mega, giga, and tera ordinarily refer to 10, 10, 10, and 10, respectively. However, when used with byte, they refer instead to 2, 2 , 2, and 2 . That is, a kilobyte is not 1000 bytes but 1024 bytes. The reason is that addresses, the numbers that refer to the location of digital data, are binary numbers, so a kilobyte is the total number of bytes that can be addressed by a ten bit address, and it carries the kho prefix because it is the power of 2 closest to 1000. Likewise a megabyte is 1,048,576 bytes because it is the power of 2 closest to 1,000,000, and represents the number of locations addressable by 20 bits.
