Google Chrome OS is a project by Google Inc. to develop a lightweight computer operating system devoted to using the World Wide Web.[1] Announced on July 7, 2009, it is based on Google's Chrome web browser and the Linux kernel. It will initially be targeted at netbooks,[2] and is set to be released during the second half of 2010.[3] It will run on systems with either x86 or ARM processors.[4] Google has stated that the Google Chrome OS project will be open source[5] by the end of 2009, and that it will use "a new windowing system",[6] as opposed to the X Window System, which is the standard for Linux.
