Definition: Chromium OS

An open source operating system from Google based on the Linux kernel. Introduced in 2009, Google's Chrome OS and Chrome browser were derived from Chromium. The source code for Windows, Mac and Linux is available from the Chromium website (www.chromium.org).

The Browser Is Two Modules
Designed for the Web, Chromium's user interface is the Chromium browser, and the Chromium WebKit rendering engine displays and executes the Web page. Because it deals with untrusted content, it runs in a sandbox that prevents illegal system calls to be executed from the page. Via interprocess communications, the rendering engine interfaces with the browser kernel, which interacts with the operating system. If a Web application crashes, the Chromium OS is able to cancel that operation without the browser or itself crashing. See WebKit, Chromebook, Chrome browser and Cloud Ready.
