Samsung Ativ (stylized as ATIV) is the branding used for personal computers and mobile computing devices produced by Samsung Electronics running the Windows 8, Windows RT, and Windows Phone 8 operating systems. The term "Ativ" is a reversal of the word "vita", meaning "life".
The brand was originally used for Samsung's Windows 8 and Windows Phone 8-based tablets and smartphones; in April 2013, Samsung announced that it would extend the brand to all of its future PC products (including conventional laptops and desktop computers; such as its newly-introduced Ativ Book 5 and Ativ Book 6), and re-branded some of its existing product lines and models under the Ativ name, including "Ativ Book" (for laptops), and "Ativ One" (for all-in-one computers).
