standard
  • An established reference against which comparisons or verifications may be made. A de facto standard is adopted through continued use and acceptance, while a de jure standard is issued or endorsed by a entity which establishes standards.
  • A component, circuit, device, instrument, piece of equipment, or system, whose parameters or specifications are known precisely, and which serves as a basis for verification, comparison, or the like. For instance, a standard capacitance, or a standard resistance.
  • A component, circuit, device, instrument, piece of equipment, or system whose output, such as a frequency, voltage, amplitude, level, or the like, is precisely known, and which serves as a basis for comparisons or verifications. For example, an atomic frequency standard.
  • A specification, such as that for software, hardware, a format, or protocol, which is widely accepted, or assigned to serve as a model or basis. For instance, the OSI Reference Model.
  • A transmission and reception system which is established for a given communications or broadcast format. Examples include the high-definition, NTSC, and PAL TV standards.
