Analysis of information sources in references of the Wikipedia article "Air gap (networking)" in English language version.
In high-security situations, various forms of data often must be kept off production networks, due to possible contamination from nonsecure resources — such as, say, the Internet. So IT admins must build enclosed systems to house that data — stand-alone servers, for example, or small networks of servers that aren't connected to anything but one another. There's nothing but air between these and other networks, hence the term air gap, and transferring data between them is done the old-fashioned way: moving disks back and forth by hand, via 'sneakernet'.
Stock exchange internal network computer systems are so sensitive that they are "air gapped" and not attached to the internet, in order to protect them from attack, intrusion, or other malicious acts by third party adversaries.
Industrial internal network computer systems are so sensitive that they are "air gapped" and neither attached to the internet nor insecurely connects to the corporate network, in order to protect them from attack, intrusion, or other malicious acts by third party adversaries.

(...Boeing...) wouldn't go into detail about how (...it...) is tackling the issue but says it is employing a combination of solutions that involves some physical separation of the networks, known as air gaps, and software firewalls.

For example, top-secret data might be kept on a different computer than data classified merely as sensitive material. Sometimes, for a worker to access information, up to six different computers can be on a single desk. That type of security is called, in typical intelligence community jargon, an air gap.
