Unidirectional
From Wikipedia, the free encyclopedia
Unidirectional means allowing flow in only one direction. One way streets are unidirectional.Moving in one direction. So are transistors. In mathematics, in graph theory, a directed graph has unidirectional edges, represented by arrows.
In audio technology, the MIDI specification only allows for unidirectional cables. The only routing available for the cables is through the use of a 5pin DIN socket which can be connected to 1 of three sockets - MIDI In, MIDI Out or MIDI Thru.
