signals
This word functions as a bridge between the physical world of gestures and the invisible world of technology. It carries a sense of intentionality; a signal is not a random occurrence but a deliberate piece of data designed to trigger a specific reaction in a receiver. In social contexts, it often describes subtle, non-verbal cues that hint at a hidden meaning or desire. In technical contexts, it refers to the raw transmission of data, where the primary concern is the clarity and strength of the connection rather than the social nuance.
Countable when referring to specific indicators or gestures (three red signals). Uncountable when referring to the general quality of a transmission (the signal is weak).
