2. Introduction
 Google Chrome OS is a Linux-based operating
system designed by Google to work exclusively with web
applications
 Google announced the operating system on July 7, 2009 and
made it an open source project, called Chromium OS, in
November, 2009.
 Since Google Chrome OS is aimed at users who spend most of
their computer time on the Web, the major application on the
device is a browser incorporating a media player and a file
manager.

3. HISTORY OF CHROME OS
• Google announced Chrome OS on July 7, 2009,
conceiving it as an operating system in which both
applications and user data reside in the cloud.
• On November 19, 2009, Google released Chrome OS's
source code as the Chromium OS project.
• Google Chrome OS code is only supported by Google
and its partners and only runs on hardware designed for
the purpose.

4. USER INTERFACE
Minimal screen space by combining applications and standard
Web pages into a single tab strip, rather than separating the two.
Handled with "panels": floating windows that dock to the bottom
of the screen for tasks like chat and music players.
Google Chrome OS would follow the Chrome browser's practice
of leveraging HTML5’s offline modes, background processing, and
notifications.

6.  Google integrates a media player into both Chrome OS and
the Chrome browser, enabling users to play back MP3s, view
Media Player , file manager JPEGs, and handle other multimedia files while offline.
 Chrome OS also includes an integrated file
manager resembling those found on other operating systems,
with the ability to display folders and their associated files, as
well as preview and manage file contents using a variety of Web
applications, including Google Docs.

8. FEATURES AND WORKING
Printing
Google Cloud Print is Google's proposed solution to help any
application on any device to print on any printer.
Link Handling
Chrome OS was designed with the intention of having user
documents and files stored on online servers. However, both Chrome OS
and the Chrome browser have unresolved decisions regarding handling
specific file type’s offline.

9. ARCHITECTURE
Google describes a three-tier architecture:
• Firmware, web browser
• System-level software and userland services
• Window manager

10. The firmware contributes to fast boot time by not digging into
for hardware, such as floppy disk drives, that are no longer common on
computers, especially netbooks.
System-level software includes the Linux kernel that has been patched
to improve boot performance.
Userland software has been trimmed to essentials, with management
by Upstart, which can launch services in parallel, re-spawn crashed jobs,
and defer services in the interest of faster booting.
The window manager handles user interaction with multiple client
windows much like other X window managers.

11. VERSIONS
• ChromiumOS Cherry (4 December 2009)
• ChromiumOS Flow (15 February 2010)
• ChromiumOS Zero (9 December 2009)
• ChromiumOS Vanilla (15 March 2011)

12. Relation to Android

13. • Google's successive introduction of the popular Android and
Google Chrome OS has put the company behind two open
source, client-based operating systems
• Steven Levy wrote that "the dissonance between the two
systems was apparent" at the 2011 Google I/O developer
conference.
• Sergey Brin suggested that the two systems "will likely
converge over time.”

14. Advantages :
1.Fast booting.
2.Simple , intuitive , beautiful.
3.Less hassle than traditional operating systems.
Disadvantages :
1.More internet expenditure.
2.Some functionalities disable when offline.
3.Less storage memory.

15. CONCLUSION
Google’s Chrome OS may or may not make it, but the attempt
shows how far the computer industry has come from a bulky
PC chained to a desk by its power cord and Ethernet cable.
The computer is evolving from those dinosaurs to a smaller,
mobile model that is always connected to the web. The iPhone
brought us apps that are lightweight so users don’t get bogged
down by smaller processors and slower wireless web
connections on mobile devices. Google’s Chrome OS attempts
to keep that speed, while preserving a platform for Google to
make money through advertising.
