Chrome OS is an operating system developed by Google that uses the Google Chrome browser as its primary interface. It is built on the Linux kernel and primarily supports web applications. Chrome OS is designed to be fast, secure, and simple to use. It boots quickly, resumes from sleep instantly, and runs all web pages and apps in isolated sandboxes for security. As a browser-based OS, Chrome OS provides speed, automatic updates, and easy access to files and apps stored online through the cloud. However, it is currently hardware dependent and does not support applications like Microsoft Office without web versions.

2. Introduction
● What is OS?
In short,a program designed to run other programs.
Main roles:
● IO Management
● Processor Management
● File Management
● Memory Management

3. Introduction
What is Chrome Browser?
● It is a Browser Developed by Google.
● HTML 5 and CSS3
Supports.
● Lot More Faster than
any other Browser.
● Available for all major
platforms
● More than 2 Bn. User

4. Introduction
Android :
● Mobile operating system
● Built on Open Linux Kernel
● Provides a better platform
for smartphones.
● Developers can create rich applications to provide more
relevant user experience.

5. What is a Chrome OS?
● Chrome OS is an operating system designed by Google that is
based on the Linux kernel and uses the Google Chrome web
browser as its principal user interface. As a result, Chrome OS
primarily supports web applications.
● Google announced the project in July 2009, conceiving it as an
operating system in which both applications and user data
reside in the cloud: hence Chrome OS primarily runs web
applications.

6. Google Chrome OS: An
Internet OS
● Extension of Chrome Browser
And Android
● Targeted for use on Netbooks
● First OS dedicated to internet
● Created Specially for Computers of
new age.
Tim O’Reilly defines:
‘simply use our
facilities, and
the complexity will
go away’
thing is Internet OS.

7. Specification
● Company/developer Google Inc.
● Programmed in C,C++
● OS family Linux
● Kernel type Monolithic:Linux kernel
● Default UI On the Google Chrome browser
● Working state Preinstalled on specific hardware
(Chromebooks,Chromeboxes)
● Update Method Rolling release(frequent Updates)

8. Features
● Speed
● Simplicity
● Security
● “Hardened OS”
– Auto Updation
– SandBox
● Use of Cloud
● Includes Binary Packages
On the Chrome notebook,
each web page and
application visited runs in a
restricted environment called
a “sandbox.” So if you visit
an infected page, it can’t
affect the other tabs or apps
on your computer, or
anything else on your
machine. The threat is
contained.

9. Speed
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’
● Boots in 10 Seconds
● Resumes from sleep instantly

10. Speed
Traditional OS Chrome OS
=
7 Seconds of Boot time
3 Seconds of Log in time
Boot processes

11. Simplicity
● Just a Browser
with tabs
● Requires Google
Id to Log In
● Customizabale as
per user
requirement

12. Security
● It uses the principle of “defense in depth” to provide multiple
layers of protection, so if any one layer is bypassed, others are
still in effect.
● Small list of Verified Programs: Signed and verified before each
use
● Run in Secure Sandbox mode
● File system is locked down:
– Read only Root File System in EEPROM
– Self automatic updates for entire OS

13. Security
Traditional OS Chrome OS
➢ Applications have
permissions same as user.
➢ Can communicate each
other easily.
➢ Web application have
limited permission.
➢ They are treated as
untrusted apps and run in
encapsulated environment

14. Other Features
• Supports external Memory Devices Ex. SD Card
• Explores external devices in Chrome Browser itself
● Can be also work offline
● There is a chrome app store called web store,where we can do stuffs in the
app
• Embedded Video Player is provided as a feature of HTML 5
• Videos are played as separate tab
• Chatting feature is readily available
• V8 JavaScript engine is used to increase browser speed

15. More Features
• Chrome OS is hardware dependent currently supports x86
and ARM (Advanced RISC Machine)architecture
• Developer mode is included with a switch mode button
• Developer mode allows developer to install their own builds
of Chrome OS

16. Advantages
• Free, Open Source : Lots of opportunity for developers
• Low hardware cost
• New web based applications need to be
• User friendly

17. Limitations
• Hardware specific
• No physical data storage
• Does not support Microsoft Office
