The species that communicates through binary code is the Bynar. The Bynars are small, highly intelligent humanoids introduced in the Star Trek: The Next Generation episode “11001001.” Their name and communication style reflect their dependence on binary information and computer systems.
Bynars live on the planet Bynaus, where they maintain and enhance the world’s vast computer network. They communicate in rapid binary sequences and operate in bonded pairs, with each individual sharing a close neurological and informational connection with a partner. Their society’s survival depends on preserving and processing data.
In “11001001,” two Bynars appear to steal the USS Enterprise-D while secretly using its computer systems to save the population of Bynaus from a catastrophic event. The episode’s title is itself a binary number. Bynars are often confused with the Borg because both are associated with technology and collective intelligence, but Bynars remain individual beings and are not assimilated into the Borg Collective.
