Non-Connected Hardware

Non-connected hardware refers to physical computing devices or components that operate without network connectivity, such as local storage drives, standalone sensors, or offline embedded systems. This concept emphasizes devices that function independently of internet or network access, often for security, reliability, or simplicity in isolated environments. It contrasts with connected hardware like IoT devices or networked servers, focusing on self-contained operation.

Also known as: Air-gapped hardware, Offline hardware, Standalone hardware, Isolated devices, Non-networked hardware

Why learn Non-Connected Hardware?

Developers should understand non-connected hardware when building systems requiring high security (e.g., air-gapped networks), reliability in offline scenarios (e.g., industrial control systems), or cost-effective solutions without network dependencies. It's crucial for applications in critical infrastructure, legacy systems, or environments where connectivity is impractical or risky, such as in remote locations or secure facilities.
