A bit of storage or capacity is exactly the unit that supports
storing/transmitting a bit of information.
As with bandwidth, the two variants are not unrelated.
As to writing this all down (RFC style), one might, e.g, write down all
the alternate definitions or interpretations of a word, and put them,
e.g., in an alphabetical list, and e.g., call it a "dictionary".
All these definitions are in common use, and usage evolves. Electronics
has established terms it too cribbed from other disciplines and contexts
(e.g., valves), and they are evolving as well.
