Linux-based OS designed by Google to work exclusively with web apps

Basically a fulltime networking OS

Developed from Chromium open source project

No built-in Apps

BASICS OF AN OS• Provides user interface

• A software that controls the overall operation of a computer

• Manages hardware resources

• Provides common services for execution of application softwares

Modern day Operating Systems

♣ Sun Solaris

♣ Linux

♣ Microsoft Windows

♣ Apple Mac OS X

♣ Chromium OS

Traditional OS vs. Chrome OS

Featuresof

Chrome OS

Instant web

Synchronization

Built-in Security

Forever fresh

Amazing Web apps

Instant Web Access

• Faster boot up enables instant web access

• The chrome OS directly loads into the chrome browser

• OS works inside the browser

Synchronization

• All the information is synchronized with cloud

• Hence is accessible from any device connected to the network

Built-in Security

• Verified Boot

• Part of the OS will reside in a read only section of memory

• Can run multiple tabs and each one is locked down from all others.

Forever Fresh and Amazing Web Apps

• As all the apps are in the web there is no need to update them

• There are thousands of new apps available in the cloud

• No need to install or uninstall

• Google itself provides the chrome web store were we could find almost any of the day to day apps

SOFTWARE ARCHITECTURE

• Three-tier architecture– Firmware– System-level software and user land services– Chromium and the Window Manager

Firmware

Firmware

• Plays a key part to make booting of the OS faster and more secure

• Isn’t backwards compatible with a large amount of legacy hardware

• Firmware Functionality– System Recovery– Verified Boot– Fast Boot

System-level and user-land software

System-level and user-land software

• The Linux kernel, drivers, and user-land daemons• User-land services are managed by Upstart• Services

o D-Buso Connection Managero WPA Supplicanto Autoupdateo Power Managemento Xscreensavero Standard Linux services

Chromium and the Window Manager

• Handles user's interaction with multiple client windows

Security Overview

• Verified Boot • OS Hardening• Secure Auto Update• Making the browser more modular• Phishing, XSS, and other web vulnerabilities• Data protection

Drawbacks of the Chrome OS

• Web-centric, requires anytime access to the Internet to maximize Chrome usage.

• Reliable high speed Internet connection to run data-heavy applications

• Lack of offline support

CONCLUSION

The chrome OS emerged as a Revolutionary open source OS

It is light weight, simple and easy to handle OS

It is most suitable for all net-based systems

The Chromium OS may end the monopoly of Windows in the future

Future Works

• Auto-login – User doesn’t have to login every time he boots

• Biometrics, smartcards and Bluetooth – Biometric authentication technologies may be used– Smartcards may be used for login in future– Bluetooth device pairing is a future authentication
