Google Chrome OS is a lightweight, web-based operating system developed by Google. It is based on the Linux kernel and focuses on running web applications. The OS is designed for netbooks and other lightweight devices. It emphasizes speed, simplicity, and security. When booting, Chrome OS loads directly into the Chrome browser where users can access web apps tied to their Google account. All data and apps are cloud-based. The OS aims to challenge Microsoft's dominance with Windows.

8. History
8
 Google developers began coding the operating system in 2009.Inspired by the
growing popularity and lower power consumption of net-books and the focus
of these small laptops on Internet access. For developing new OS they
monitored the usage patterns of some 200 Chrome OS machines used by Google
employees.
 On November 19, 2009, Google released Chrome OS's source code as the
“Chromium OS project”.Google demonstrated an early version of the operating
system.
 In March 2010, Google indicated that they are developing two versions of the
operating system, a consumer version and an enterprise version.
 In December 2010 Google showed off a development Google Chrome OS
laptop

Chrome OS consists of three major components:-
 The Chromium-based browser and the window manager.
 System-level software and user-land services: the kernel, drivers,
connection manager, and so on .
 Firmware.

14. Compatibles Hardwares
 Companies like developing hardwre for the operating system include
Acer , Hp, Tosibha, Intel ,Samsung, & Dell are asociatives for
hardware support currently.
 In July 2010 Many Companies like Hp, Dell are refused the Working
proposal for Chrome OS.
 In April 2010 when google got some tie-ups & Merging with some
associates it confirmed that Google will supply the operating System
for free but it will be up to hardware manufacturers and retailers to set
their own prices for the devices.

15. System Boot
 Chrome OS boot Process is much faster than any other OS. Since
chromebook are specially designed for chrome OS so firware doesnot
have to search components.
 There is no Boot loader, therfore directly jumped to the Kernel.
 There is no start up application other than the browser so no waiting for
normal start up. Applications.
 Since Finally it already Knows your Google Account so it again saves the
time.
 So In turn Google chrome is on can often boot in 5 seconds.

20. Chrome OS on Microsoft
20
• Google plans to attack Microsoft's core business by taking on the software
giant's globally dominant Windows operating system for personal computers.
• Google did not say how much it would charge for the operating system (OS), but
End expects Google to charge at most a nominal fee or make it free, saying the
company's business model has been to earn revenue from connecting
applications or advertising.
• Google is planning to capture Microsoft Share of 90%.
• Google is going to lock in partnerships with PC maker such as HP & Dell.
• HP & Dell are using 90% + windows on most of there products

21. Current Research
• Presently Working on “Chromium OS” Project the sub OS of Chrome &
just like chrome browser look a like Chromium. But more fast and Secure
and cover up all chrome OS faults .
• And Also working with Android to make the Operating system & Web
application Much better.
• And further Chances to be release the Open Source OS Free to all
systems or hardware support globally just to end the era of microsoft .
• And new recent update is has been introduced “Aura shell” that gives the
traditional desktop familiar look like window.
• Soon Chrome Os /chromium OS (Mordern & Updated) is available to
every individual.
21

22. Merits & Demerits
(i)Merits:
• OS is free or can say free of charge.
• The Chrome OS is impressive, especially the loading speed of the system.
• Even if an operating system that works in the cloud, Chrome OS has a feature to work offline,
providing the tools even without being connected. Google Docs, for example, can be used normally
even without any internet connection. Changes made to documents are automatically synchronized with
the documents online so the computer is connected to the internet.
• Convinent And easy to use.
(ii) Demerits:
• Installing a bit laborious and also presents some small bugs.
• Although most users who often work with your computer is connected all the time, that does not
necessarily mean that everyone has a quality signal. Especially in Brazil, where the infrastructure and
the prices do not allow everyone to have access to high-speed connection, this can mean trouble.
• Storing information on the Internet can also be a recipe for cybercriminals. After all, a raid on an online
service not only undermines the login information of users, but all documents stored there, which can
range from simple school projects to confidential reports on companies.
22

23. Conclusion
As the web becomes more and more the main place users spend
their time on the internet, Chrome Operating System will become
increasingly attractive. Eventually we could see a machine that
only needs access to the web to run applications and store data to
the cloud. In this scenario Google’s Chrome Operating System will
already be one up on the competition.
