11. Instant-Web/Cloud Storage
• Chrome OS offers instant Web Access.
• The Chromebooks come with a very low storage of about 16 or 32 GB.
• An Additional 15 GB is available for the user on Google Drive as Cloud
Storage.

12. Applications
• Chrome OS allows users to install any application from Chrome Web Store.
• These are called chrome apps and they can be anything from games to picture
editing tools.
• Browser based applications known as extensions can also be installed.
• In future all Android Apps will also be available for Chrome OS.

13. Security
• Chromebooks use the principle of "defense in depth" to provide multiple
layers of protection.
• Surprisingly Chrome doesn’t needs an Antivirus Program.
• Executable files, that a virus needs, can’t run in Chrome OS.
• On a Chromebook, each web page and application runs in a restricted
environment called a "sandbox." If the Chromebook is directed to an infected
page, it can’t affect the other tabs or apps on the Computer.
• Every time the Chromebook starts up, it does a self-check called "Verified
Boot.“ It makes sure the OS hasn’t been tampered with.

14. Drawbacks
• It is designed to specifically target internet gen.
• To get most out of Chrome OS the Users need to be able to access internet.
• The offline storage capacity is very little. Though a Memory Card slot is
available in a Chromebook to expand the storage.
• Many ‘Windows’ applications don’t support Chrome OS.
• Chrome OS does not runs resource intensive programs.
• No support for another web –
• browser
