Cyberdyne Systems is the fictional company associated with manufacturing the T-800 in James Cameron’s Terminator films.
In The Terminator, Cyberdyne’s research eventually leads to Skynet and the development of advanced military machines. The company becomes even more important in Terminator 2: Judgment Day, where the remains of the first film’s Terminator and its advanced processor influence Miles Dyson’s work.
Cyberdyne is not the same as Skynet. Cyberdyne is the corporation and research organization, while Skynet is the artificial intelligence defense system that becomes self-aware and launches a nuclear war. This distinction is central to the sequel’s attempt to prevent the future catastrophe.
The company name is sometimes confused with fictional corporations from other science-fiction franchises. Weyland-Yutani belongs to Alien, while Tyrell Corporation belongs to Blade Runner.
