WebA space is totally disconnected if it has no non-trivial connected subsets. What about the empty space? It is connected, in fact vacuously so as it lacks non-empty subsets in the first place. Consequently it is not disconnected. On the other hand it is totally disconnected as its only subsets are (connected but) trivial.
