Data rate and data transfer rate can refer to several related and overlapping concepts in communications networks:
Achieved rate
*
Bit rate
In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time.
The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction ...
, the number of bits that are conveyed or processed per unit of time
**
Data signaling rate
In telecommunications, data signaling rate (DSR), also known as gross bit rate, is the aggregate rate at which data passes a point in the transmission (telecommunications), transmission data link, path of a data transmission system.
Properties
...
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
Network throughput (or just throughput, when in context) refers to the rate of message delivery over a communication channel in a communication network, such as Ethernet or packet radio. The data that these messages contain may be delivered ov ...
, the rate of successful message delivery, or level of bandwidth consumption
*
Transfers per second
Capacity
*
Bandwidth (computing)
In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth.
This definition of ''bandwidth'' is in contrast to the field of signal ...
, 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
