Black box

A black box can mean different things depending on the context:
1. General Meaning – Something whose internal workings are not visible or understood, but inputs and outputs can be observed. For example, in science or computing, a system might be treated as a “black box” if only its results matter, not the process inside.
2. Aviation – In airplanes, a black box refers to the flight data recorder (FDR) and cockpit voice recorder (CVR). Despite the name, they are usually bright orange to make them easier to find after crashes. They store vital flight information and cockpit conversations to help investigators understand what happened.
3. Electronics & Engineering – A black box can describe a device or system whose function is known, but its inner components or mechanisms are hidden or not necessary to know for use.
4. Business & AI – Sometimes used to describe decision-making systems (like AI models) where the logic behind results is complex and not easily explainable.

Do you mean black box in airplanes, or in a more general sense like computing/AI?
