I work on an air-gapped network. The most important thing that the words "air gap" communicate is that there is no connection, nothing at all, to anything outside the network. The only way to move anything on or off are using disc drives (no USB for security reasons). The word "private network" does not really communicate that there is a physical gap of no wires at all from the computers on the network and everything else on the internet.
