Discrete means as opposed to continuous.
For, instance, people may ask questions about discrete electric charges, discrete spacetime, discrete energies, etc.
If discretization is vital/essential to the question then tag it with the discrete tag.
Currently there is 37 questions tagged with the discrete tag.
A related tag (in case of quantum theory) is the quantization tag.

2$\begingroup$ True, but it's too broad . . Discrete spacetime (!) being grouped together with discrete energy levels? $\endgroup$ Commented Aug 4, 2013 at 13:32

3$\begingroup$ The discrete tag (and, e.g., the fourier-transform tag, the symmetry tag, etc.) offers an orthogonal classification to the more traditional classifications into subjects like qmech, clas mech, stat mech, fluid dyn, etc. I find the discrete tag useful. $\endgroup$– Qmechanic ModCommented Aug 4, 2013 at 15:16

1$\begingroup$ @Qmechanic Just out of curiosity, don't we define meta-tags as something that couldn't stand as it's own tag and must be paired with another to make sense? Doesn't discrete fall into that category as on it's own, it doesn't tell you anything and must be paired with spacetime, energy, etc to make sense? $\endgroup$– tpg2114Commented Aug 5, 2013 at 18:07

$\begingroup$ @tpg2114: That "definition" isn't very precise. For example . , a tag with higgs-mechanism would always be with quantum-field-theory, string-theory, etc. $\endgroup$ Commented Aug 12, 2013 at 15:54
