  2. Data-rate units - Wikipedia

    en.wikipedia.org/wiki/Data-rate_units

    The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...

  5. Data rate - Wikipedia

    en.wikipedia.org/wiki/Data_rate

    Bit rate, the number of bits that are conveyed or processed per unit of time . Data signaling rate 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

    en.wikipedia.org/wiki/Units_of_information

    Therefore, the choice of the base b determines the unit used to measure information. In particular, if b is a positive integer, then the unit is the amount of information that can be stored in a system with b possible states. When b is 2, the unit is the shannon, equal to the information content of one "bit" (a portmanteau of binary digit [2]).

  7. Byte - Wikipedia

    en.wikipedia.org/wiki/Byte

    In data transmission systems, the byte is used as a contiguous sequence of bits in a serial data stream, representing the smallest distinguished unit of data. For asynchronous communication a full transmission unit usually additionally includes a start bit, 1 or 2 stop bits, and possibly a parity bit , and thus its size may vary from seven to ...

  8. Bit rate - Wikipedia

    en.wikipedia.org/wiki/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. [1]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). [2]

  9. List of interface bit rates - Wikipedia

    The figures below are simplex data rates, which may conflict with the duplex rates vendors sometimes use in promotional materials. Where two values are listed, the first value is the downstream rate and the second value is the upstream rate. The use of decimal prefixes is standard in data communications.
