    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 ...

    en.wikipedia.org/wiki/IEEE_1394

    1394b and later, full-duplex 800–3200 Mbit/s (100–400 MB/s) IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic .

    1.6 × 10 12 bits (200 gigabytes) – capacity of a hard disk that would be considered average as of 2008. In 2005 a 200 GB harddisk cost US$100, [5] equivalent to $156 in 2023. As of April 2015, this is the maximum capacity of a fingernail-sized microSD card. 2 41

  6. 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).

  8. Transfers per second - Wikipedia

    en.wikipedia.org/wiki/Transfers_per_second

    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. The bit rate for this example is 64 Gbit/s (8 × 8 × 10 9 bit/s).
