The formula for a data transfer rate is: Channel width (bits/transfer) × transfers/second = bits/second. Expanding the width of a channel, for example that between a CPU and a northbridge , increases data throughput without requiring an increase in the channel's operating frequency (measured in transfers per second).
Terabit per second (symbol Tbit/s or Tb/s, sometimes abbreviated "Tbps") is a unit of data transfer rate equal to: 1,000 gigabits per second 1,000,000 megabits per second
While the gross data rate equals 33.3 million 4-bit-transfers per second (or 16.67 MB/s), the fastest transfer, firmware read, results in 15.63 MB/s. The next fastest bus cycle, 32-bit ISA-style DMA write, yields only 6.67 MB/s .
This is a list of countries by Internet connection speed for average and median data transfer rates for Internet access by end-users. The difference between average and median speeds is the way individual measurements are aggregated.
Technically, the hertz is a unit of cycles per second, but many people refer to the number of transfers per second. Careful usage generally talks about "500 MHz, double data rate" or "1000 MT/s", but many refer casually to a "1000 MHz bus," even though no signal cycles faster than 500 MHz.
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
In telecommunications, effective data transfer rate is the average number of units of data, such as bits, characters, blocks, or frames, transferred per unit time from a source and accepted as valid by a sink. Note: The effective data transfer rate is usually expressed in bits, characters, blocks, or frames per second. The effective data ...
The symbol rate is measured in baud (Bd) or symbols per second. In the case of a line code, the symbol rate is the pulse rate in pulses per second. Each symbol can represent or convey one or several bits of data. The symbol rate is related to the gross bit rate, expressed in bits per second.
