Etymology: "Airgaps" is the plural of "airgap", a noun meaning physical network separation: a computer or network kept completely disconnected from other systems, with no cable, wireless link or other path between them. The word is a compound of "air" and "gap", combining the everyday senses of open space with a break or opening. The image is literal: the separation is a real empty space, not merely a software barrier. Because the term is formed transparently from two plain English words, its meaning can be read straight off its parts. The plural form simply applies the usual rule for nouns, so "airgaps" refers to more than one such separation, as when a security policy specifies several isolated systems.
