Data rate

'''Data rate''' and '''data transfer rate''' can refer to several related and overlapping concepts in communications networks:

==Achieved rate== * Bit rate, the number of bits that are conveyed or processed per unit of time ** Data signaling rate or gross bit rate, a bit rate that includes protocol overhead * Symbol rate or baud rate, the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time * Data-rate units, measures of the bit rate or baud rate of a link * Data transfer rate (disk drive), a data rate specific to disk drive operations * Throughput, the rate of successful message delivery, or level of bandwidth consumption * Transfers per second

==Capacity== * Bandwidth (computing), the maximum rate of data transfer across a given path * Channel capacity, an information-theoretic upper bound on the rate at which data can be reliably transmitted, given noise on a channel
