Meaning and Definition
A physical board, panel, or display, often found in public spaces or control centers, that uses lights, letters, or symbols to present important and changing information such as departures, arrivals, messages, warnings, or statuses.
In modern contexts, it can also refer to a digital display performing the same function, and historically, to a board in a railway signal box from which levers controlling trackside signals were operated. In technology, it can be a metaphorical control panel or dashboard displaying system status signals.
