In case of serial communications, the gross bit rate is related to the bit transmission time T b In digital communication systems, the physical layer gross bitrate, raw bitrate, data signaling rate, gross data transfer rate or uncoded transmission rate (sometimes written as a variable R b or f b ) is the total number of physically transferred bits per second over a communication link, including useful data as well as protocol overhead.

The International Standard ( IEC 80000-13) specifies different abbreviations for binary and decimal (SI) prefixes (e.g. = 1 Tbit/s (one terabit per second, i.e., one trillion bits per second)īinary prefixes are sometimes used for bit rates. = 1 Gbit/s (one gigabit per second, i.e., one billion bits per second) = 1 Mbit/s (one megabit per second, i.e., one million bits per second) = 1 kbit/s (one kilobit per second, i.e., one thousand bits per second)

= 1 mbit/s (one millibit per second, i.e., one bit per thousand seconds) When quantifying large or small bit rates, SI prefixes (also known as metric prefixes or decimal prefixes) are used, thus: 0.001 bit/s

In most computing and digital communication environments, one byte per second (symbol: B/s) corresponds to 8 bit/s. The non-standard abbreviation bps is often used to replace the standard symbol bit/s, so that, for example, 1 Mbps is used to mean one million bits per second. The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s). 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. For disk drives, see data transfer rate (disk drive).
