Kilobits Per Second: a measure of data transfer speed. Modems, for example, are measured in Kbit/s. Note that one Kbit/s is 1,000 bits per second, whereas a kilobyte is 1,024 bytes. Data transfer rates are measured using the decimal meaning of K whereas data storage is measured using the powers-of-2 meaning of K. This measure is often expressed as “Kbps”. However, this is also sometimes used to mean “Kilobytes per second” (as well as the the more common “KBps”). To avoid confusion the PC Technology Guide uses “Kbit/s” throughout.
