The output (outputs) of a reversible gate that is (are) not used as input to other gate or the output (outputs) that is (are) not treated as a primary output is (are) called garbage output (outputs). The unutilized outputs from a gate are called garbage outputs. A heavy price is paid for every garbage output. So, for any circuit design, the fewer the garbage outputs, the better.
