In telecommunications Telecommunication is the transmission of signals over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags or heliograph. In modern times, telecommunication typically involves the use of electronic devices such as telephones, television, radio or computers. Early and computing Computing is usually defined as the activity of using and improving computer technology, computer hardware and software. It is the computer-specific part of information technology. Computer science is the study and the science of the theoretical foundations of information and computation and their implementation and application in computer systems, bitrate (sometimes written bit rate, data rate or as a variable R or fb) is the number of bits A bit is the basic unit of information in computing and telecommunications; it is the maximum amount of information that can be stored by a device or other physical system that can normally exist in only two distinct states. These may be the two stable positions of an electrical switch, two distinct voltage or current levels allowed by a circuit, that are conveyed or processed per unit of time.
The bit rate is quantified using the bits per second In telecommunications, bit rate or data transfer rate is the average number of bits, characters, or blocks per unit time passing between equipment in a data transmission system. This is typically measured in multiples of the units bit per second or byte per second (bit/s or bps) unit, often in conjunction with an SI prefix The International System of Units specifies a set of unit prefixes known as SI prefixes or metric prefixes. An SI prefix is a name that precedes a basic unit of measure to indicate a decimal multiple or fraction of the unit. Each prefix has a unique symbol that is prepended to the unit symbol. The SI prefixes are standardized by the International such as kilo- Kilo is a unit prefix in the International System of Units (SI) denoting 103 or 1000. For example: (kbit/s or kbps), mega- mega is an SI prefix in the SI system of units denoting a factor of 106, 1,000,000 (one million) (Mbit/s or Mbps), giga- Giga is a prefix in the SI system of units denoting 109, or 1,000,000,000. The Oxford English Dictionary reports the earliest written use of giga- in this sense to be in the Reports of the IUPAC 14th Conference in 1947: "The following prefixes to abbreviations for the names of units should be used: G giga 109×". Giga comes from the (Gbit/s or Gbps) or tera- tera is a prefix in the International System of Units (SI) denoting 1012, or 1,000,000,000,000 (1 trillion in short scale) (Tbit/s or Tbps). Note that, unlike many other computer-related units, 1 kbit/s is traditionally defined as 1,000 bit/s, not 1,024 bit/s, etc, also before 1999 when SI prefixes were introduced for units of information in the standard IEC 60027-2.
The formal abbreviation for "bits per second" is "bit/s" (not "bits/s"). In less formal contexts the abbreviations "b/s" or "bps" are often used, though this risks confusion with "bytes The byte is a unit of digital information in computing and telecommunications. It is an ordered collection of bits, in which each bit denotes the binary value of 1 or 0. Historically, a byte was the number of bits (typically 6, 7, 8, or 9) used to encode a character of text in a computer and it is for this reason the basic addressable element in per second" ("B/s", "Bps").
