QNX
QNX is a specialized operating system mainly used in cars' entertainment and information systems, as well as in other devices that need to work reliably without interruption. Think of it as the "brain" that runs the touchscreens and digital displays in modern vehicles. It's different from regular computer operating systems like Windows because it's designed to be extremely reliable and respond very quickly, which is crucial for automotive safety. Car manufacturers like Ford, BMW, and Toyota often use QNX in their vehicles. When you see this on a resume, it usually means the candidate has experience working with automotive software or embedded systems.
