What is the difference between KB/s and Kb/s?
The main units of modem speed are: · KB/s or KBps = kilobytes per second · Kb/s or Kbps = kilobits per second When transmitted over a modem, there are ten bits per byte (eight data bits plus a start bit and a stop bit). So if one modem seems ten times faster than another, it’s because different units are being used.
