data recorders
Systems storing events
Data recorders are devices that capture and store information for later retrieval.
The term covers everything from simple logging instruments to sophisticated systems: The flight data recorder survived the crash intact.
In aviation, data recorders (often called black boxes) preserve flight parameters and cockpit audio.
Similar devices appear in vehicles, industrial equipment, and scientific instruments—anywhere continuous monitoring matters.
