k - technical definition

kilo (k). From Greek khilioi, meaning thousand.
In transmission systems, kHz (kiloHertz) is a thousand (10 3 ) Hertz, kbps (kilobit per second) is a thousand (10 3 ) bits per second, and km is a thousand (10 3 ) meters. In transmission systems, therefore, a thousand is exactly 1,000, since the measurement is based on a base 10, or decimal, number system.
In computing and storage systems, a kB (kiloByte) is actually 1,024 (2 10 ) bytes, since the measurement is based on a base 2, or binary, number system.The term kB comes from the fact that 1,024 is nominally, or approximately, 1,000. So, 64 kB of memory is actually 65,536 (2 16 ) bytes.
