uni-directional
Only one way
Uni-directional means moving or operating in only one direction.
A uni-directional microphone picks up sound from one direction while rejecting others.
Uni-directional traffic flow moves one way only.
The term appears in technical contexts—electronics, acoustics, data transmission—where direction of flow matters.
Also spelled unidirectional.
