unidirectional
Moving one way
Unidirectional means moving or operating in only one direction.
A unidirectional microphone picks up sound from one side.
Unidirectional data flow moves information one way through a system.
The term appears in technical contexts—electronics, biology, traffic engineering—wherever distinguishing one-way from two-way movement matters.
