Data-rate units. In telecommunications, data transfer rate is the average number of bits ( bitrate ), characters or symbols ( baudrate ), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s).
List of interface bit rates. This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger ...
The physical layer net bitrate, [12] information rate, [6] useful bit rate, [13] payload rate, [14] net data transfer rate, [9] coded transmission rate, [7] effective data rate [7] or wire speed (informal language) of a digital communication channel is the capacity excluding the physical layer protocol overhead, for example time division ...
In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, [ 1] data bandwidth, [ 2] or digital bandwidth. [ 3][ 4] This definition of bandwidth is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications ...
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 ...
The data transfer rate of a drive (also called throughput) covers both the internal rate (moving data between the disk surface and the controller on the drive) and the external rate (moving data between the controller on the drive and the host system). The measurable data transfer rate will be the lower (slower) of the two rates.
USB 3.1 Gen 2 – new, marketed as SuperSpeed+ or SS+, 10 Gbit/s signaling rate over 1 lane using 128b/132b encoding (raw data rate: 1212 MB/s). The nominal data rate in bytes accounts for bit-encoding overhead. The physical SuperSpeed signaling bit rate is 5 Gbit/s. Since transmission of every byte takes 10 bit times, the raw data overhead is ...
In order to calculate the data transmission rate, one must multiply the transfer rate by the information channel width. For example, a data bus eight-bytes wide (64 bits) by definition transfers eight bytes in each transfer operation; at a transfer rate of 1 GT/s, the data rate would be 8 × 10 9 B/s, i.e. 8 GB/s, or approximately 7.45 GiB/s
