        We introduce a certain pretopology on the digital plane $\mathbb Z^2$
and present a digital analogue of the Jordan curve
theorem for for it. We then discuss a topology on $\mathbb Z^2$ which is shown to be
a quotient pretopology of the pretopology introduced. This fact is used to prove a digital Jordan curve theorem also for this topology.
