Isochron dating can be further separated into mineral isochron dating and whole rock isochron dating; both techniques are applied frequently to date terrestrial and also extraterrestrial rocks (meteorites).
Isochronic fork Isochronic forks are forks in wires where if the acknowledging target has seen a transition on their end of the fork then the transition is assumed to have also happened on the other end of the fork too. There are two types of isochronic forks; the asymmetric types only ensure that the signal will reach the acknowledging fork tip before, or at the same time as, it will at the other fork tip, while the symmetric type ensures that both fork tips will be reached at the same time.

In a data network where the information-bearer channel rate is higher than the input data signaling rate, transmission is performed by interrupting, at controlled intervals, the data stream being transmitted.
