A CDE Definition
The transmission speed of a communications or computer channel. Transfer rates are measured in bits or bytes per second. Transfer rate and "data rate" are often used synonymously; however, technically, the transfer rate is often more than the data rate, because control signals may be sent along with data, which decreases the rate of actual data being sent. See data rate.
(1) The speed at which data is transferred within the computer or between a peripheral device and the computer, measured in bytes per second. See transfer rate and space/time.
(2) The speed at which audio and video files are encoded (compressed), measured in bits per second (see bit rate).
(3) The transmission speed of a network. For example, 100Base-T Ethernet is rated at 100 Mbps (megabits per second). Also called "bit rate." See space/time.
