kbps - Computer Definition
(KiloBits or KiloBytes per SECond) One thousand bits or bytes per second. Kbps is a measurement of peripheral data transfer or network transmission speed. The correct abbreviation is "b" for bits and "B" for bytes; however, "b" and "B" are often interchanged. See space/time, Mbps and Gbps. Lower Case "b" - Kbps, Kb/sec, Kb/s Kilobits per second is used to rate serial data transmission devices such as analog modems. Upper Case "B" - KB/sec, KB/s Kilobytes per second is used to rate parallel data transfers such as from memory to disk in earlier computers.
