Chromium - technical definition

An open source Web browser for Windows, Mac and Linux that separates processing of the Web page into two modules, each running in their own protection domain for added security. The rendering engine, which is the most complex module, displays and executes the Web page and deals with untrusted content. It runs in a sandbox that prevents certain system calls to be executed from the Web page.

Via interprocess communications, it interfaces with the browser kernel, which interacts with the operating system. If one Web application crashes, Chromium is able to cancel that operation without bringing down the entire browser and possibly the operating system. Google's Chrome browser is based on Chromium.
