Explanation IMPEDANCE: (1) In electronics, the amount of opposition a circuit presents to an AC (alternating current) signal at a given frequency. Impedance includes both a resistive (frequency-independent) and a reactive (frequency-dependent) component. (2) In acoustics, the ratio of average sound pressure to particle velocity over a given surface area and at a given frequency

- Usage The calling conventions by which a client accesses a service. An interface provides a level of abstraction that hides the implementation details of the service from the client impedance abbreviation.
