Rev-limiters are generally implemented in one of two ways.  Either through
fuel cut-off or ignition cut-off.  Most factory rev-limiters are fuel
cut-off so the engine just gets starved for fuel at the rev-limit and
can't rev any higher (unless you do something dumb like miss a shift
bigtime or shift from 3->2 when you meant to shift from 3->4).  Most
aftermarket ignition boxes or implement a rev-limiter by cutting out spark
so not all cylinders fire in a given firing sequence.

Some rev-limiters try to be a bit easier on the engine by rotating around
which cylinder(s) get loss of fuel/ignition so as not to foul a plug or
allow one cylinder to allows "freewheel".
