Cyber-technology

Cyber-Technology was a blanket term given to inventions of the Cybermen of N-Space.

Whilst being highly advanced, Cybermen could not always rely on Cyber-Technology and, when beneficial, commandeered alien technology such as Cryon refrigeration technology (TV: Attack of the Cybermen) and gravity-manipulating technology created by humans. (TV: The Moonbase)

The Cyber-Leader stated, while watching the non-human Fifth Doctor use Cyber-Technology, that humans lacked the ability to understand it, an observation which tipped him off to the Doctor's identity. (TV: Earthshock)
