Air gap
From Wikipedia, the free encyclopedia
Air gap may refer to:
- Air gap used in transformers to limit short-circuit current.
- Air gap (computing) in computer networks to isolate sections physically.
- Air gap (plumbing) in context of plumbing.
- Air gap was the area not covered by American, British or Canadian air support during the Battle of the Atlantic (1939–1945). The air gap was fully closed by 1944 as more ultra long range aviation has been diverted to the protection of convoys from Axis submarine attacks.
