“The total quantity of digital information or storage, counted as a number of bits or bytes (and their SI
and binary multiples). This is an abstract umbrella kind; its concrete specialisations are counted in bits
(quantitykind:BitDataVolume) or bytes (quantitykind:ByteDataVolume). It is a counting quantity, distinct from the
information-theoretic entropy carried by that data (see unit:SHANNON).
