Google Chrome OS

Definition of Google Chrome OS
Google Chrome OS is a Linux operating system designed by Google to work exclusively with web applications. It is intended to focus on Web applications while running a fast and simple interface, based off Google’s existing Chrome browser. Google announced the operating system on July 7, 2009 and made it an open source project, called Chromium OS, that November.
Unlike Chromium OS, which can be compiled from the downloaded source code, Chrome OS will only ship on specific hardware from Google’s manufacturing partners. The user interface takes a minimalist approach, resembling that of the Chrome web browser. Because Google Chrome OS is aimed at users who spend most of their computer time on the Internet, the only application on the device will be a browser incorporating a media player.
Google Chrome OS is initially intended for secondary devices like netbooks, not as a user’s primary PC, and will run on hardware incorporating an x86 or ARM-based processor. Chrome OS as a “hardened” operating system featuring auto-updating and sandbox features that will reduce malware exposure. Google claimed that Chrome OS would be the most secure consumer operating system due in part to a verified boot capability, in which the initial boot code, stored in read-only memory, checks for system compromises
Introduction of Google Chrome OS
Speed is an unsaid feature of the Google Chrome OS. With Google Chrome’s tremendous booting speed and more, users have a lot to say about experiencing ‘waitlessness’. Waitlessness, in Google’s terms, means never having to wait for the web.
Chrome notebooks boot in about 10 seconds and resume from sleep instantly. Websites load quickly and run smoothly, with full support for the latest web standards and Adobe Flash. The web evolves rapidly. Your Chrome notebook evolves with it. Every time you turn it on, it upgrades itself with the latest features and fixes. Annoying update prompts not included.
The portion of the operating system needed to operate the device will reside in a read-only section of memory. The rest of the operating system is integrated with the Chrome browser and, like the browser, security updates require nothing more than a reboot. Chrome OS can run multiple Web applications in multiple tabs and each one is locked down from all others, so vulnerability in one Web app can’t lead to exposure in another
Use of Cloud:
Users of devices running Chrome will have to perform all their computing online or “in the cloud,” without downloading traditional software applications like iTunes and Microsoft Office, or storing files on hard drives. Devices running Chrome will receive continuous software updates, providing added security, and most user data will reside on Google’s servers.
User data stored on the device, which is minimal, is encrypted. User data is limited to items such as user preferences. All other data will be stored in the cloud. User preferences will also be synched to a cloud account, so like any thin client. should you lose the device, you would merely log in from another one and your data and preferences should be there.
Google’s Chrome OS, is designed to be a very fast, lightweight flavor of Linux that will be available on some netbooks and other PCs by the end of the year. Google hopes to achieve this small footprint and high performance by shipping an OS with only one installed program – their own Chrome browser. Users would work, live, and save things online, using Google’s own cloud computing services and other similar utilities, like Microsoft’s Office Web Apps . This is of course a shift from today’s computing environment, where most programs are installed locally on the computer’s hard drive

Design goals for Google Chrome OS’s user interface include using minimal screen space by combining applications and standard Web pages into a single tab strip, rather than separating the two. Designers are considering a reduced window management scheme that would operate only in full-screen mode. Secondary tasks would be handled with “panels”: floating windows that dock to the bottom of the screen for tasks like chat and music players. Split screens are also under consideration for viewing two pieces of content side-by-side. Google Chrome OS will follow the Chrome browser’s practice of leveraging HTML5 ‘s offline modes, background processing, and notifications. Designers propose using search and pinned tabs as a way to quickly locate and access applications
