Are there two widely accepted meanings for digital?

* Countable number of states (modes) such as on/off etc.
  * Suitable for "things which aren't defined as signals"

* Discrete in both time and in value
  * Suitable for "things which are defined as signals" 

## Update

This question shouldn't be marked as a duplicate of [this question][1] because the other question is not about if there are two extremely common (macro and micro) definitions for digital, or not.
