Terminaattori

Terminaattori is a Finnish noun meaning "terminator." The term is used in two broad senses: a technical device that ends a transmission line to prevent signal reflections, and a reference to the Terminator franchise in popular culture.

In electronics and telecommunications, a terminaattori is a component that terminates a transmission line, helping to preserve signal integrity by matching impedance and absorbing reflected energy. It is commonly used at the ends of coaxial cables and high-speed data buses. Terminations can be passive, using resistors chosen to match the line impedance, or active in more complex systems. The concept applies across formats such as RF cables, Ethernet, CAN bus, and fiber-optic links, though implementation details vary by standard.

In Finnish-language media and discussion, terminaattori is also used as the translation or loanword for the Terminator science-fiction franchise, referring to the cyborg antagonist and to the series as a whole.

Etymology and grammar: Terminaattori is formed from Latin terminus "end" plus the Finnish agent suffix -aattori, following Finnish word formation. The usual plural is terminaattorit. The term appears in technical manuals, textbooks, and popular writing in Finnish.
