Binary Information Unit meaning

In contracts and disputes concerning data, telecommunications and IT, a binary information unit refers to the fundamental measure of digital data: the bit (binary digit). A bit has the value 0 or 1 in base-2. bandwidth and transfer speed are commonly measured in bits per second (bps), for example kbps, Mbps and Gbps. A byte equals eight bits (B, not b), so MB/s and GB/s differ by a factor of eight from Mbps or Gbps. Storage and capacity figures may use decimal prefixes (kilo, mega, giga = 10^3, 10^6, 10^9) or binary prefixes (kibi, mebi, gibi = 2^10, 2^20, 2^30). This distinction can affect service levels, bandwidth commitments, data caps, pricing, and digital evidence concerning file sizes, logs and transfer rates, as well as encryption key lengths stated in bits. Binary information unit is a descriptive technical expression rather than a defined term in UK or Irish legislation or case law; practice typically follows industry standards (for example ISO/IEC). Usage and meaning are consistent across England & Wales, Scotland, Northern Ireland and Ireland. For certainty, specify bit or byte, the prefix system (decimal/binary), and whether figures are average or peak measurements.
