Cybernetics was the study of hugely complex artificial intelligence systems, usually running on a positronic matrix and often housed inside robotic machine technology. A practical implementation of this was an android. The scientists who studied in this field were known as cyberneticists.
Mechanical replacements for body parts were called cybernetic implants. (TNG: "The Measure Of A Man") The cybernetic implants used by the Borg to augment their bodies were often referred to as Borg implants. (TNG: "The Best of Both Worlds, Part II") Captain Jean-Luc Picard noted that like all cybernetic lifeforms, the Borg could not survive without their biological components. (Star Trek: First Contact)
Romulans did not study cybernetics, which was part of a wider pattern of complete absence of any form of artificial life in Romulan culture. (PIC: "Maps and Legends") This was because Romulan culture was influenced by the Zhat Vash, a quasi-cult within the Tal Shiar that believed that the existence of artificial life would inevitably lead to Ganmadan as a result of misinterpreting the Admonition.
