Air-Gapped Device vs Cold Storage

An air-gapped device is a computer or hardware wallet physically isolated from all network connections including internet, Wi-Fi, Bluetooth, and cellular, creating an impenetrable security barrier against remote attacks by eliminating all potential network-based attack vectors.

Cold storage is a cryptocurrency security method where private keys are stored completely offline on devices never connected to the internet, eliminating remote attack vectors and providing maximum protection for long-term holdings through physical isolation from network-based threats.
