Google Chrome OS CR-48 review
What do you spend most of your time doing on a computer? For more and more
people, the answer is, in some form or another, simply browsing the web. Whether
it’s internet banking, watching the BBC iPlayer or checking your email, all these
things are now done through a web-browser. And rising the fastest among those
web-browsers is not the newly launch Internet Explorer 9, or the geeks’ favourite,
Firefox. It’s Chrome, the upstart from Google that’s been built for speed.

Investigate and answer the following questions
1. What is Chrome OS?
ANSWER: 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, that November.
Chrome OS Linux is a brand new free operating system built around the
revolutionary Google Chrome browser.
The aim of this project is to provide a lightweight Linux distribution for
the best web browsing experience on any x86 PC, notebook or Chromebook.

2. How do you install Chrome OS
1. Navigate to the Vanilla Chromium Build homepage and scroll all the way to the
top of the version listing (latest build version).
2. Click on the “Download USB Image (picture of a USB drive)” and the zipped
OS image file should begin downloading. The file is 200MB+ and should take a
while so go relax and come back in about 15-20 minutes.
3. Once the Chromium OS image has completed downloading, we will also need to
download the Windows Image Writer so that we can successfully create a
bootable image on our flash drive. The Image Writer page can be found here,
with the download link on the right hand side of the page (first green tab). This
download won’t take long (less than 1 minute on high speed internet) so you might
as well just wait until it’s done.
4. Once everything has finished downloading we must format our flash drive.
Simply insert the drive into a USB slot in your computer and wait for Windows
to mount the drive. Then navigate to “Computer”, right click on the flash drive in
the device list and select “format…”. The format menu will open, just click the
“Start” button and Windows will automatically format your flash drive.
5. Unzip the Image Writer file and open the Win32DiskImager program
(Windows Vista, 7 and x64 bit users will need to right click and select the “Run
as administrator” option). An error may, or may not, pop up when the program is
starting. It’s referring to a floppy drive that is not installed on your machine,
dismiss the error by selecting “Ok”.
6. Unzip the Chrome OS .tar.gz image file you downloaded by using WinRAR or
7Zip and make sure the extracted files are in an easily navigable directory.
7. In the Image Writer menu select the correct drive letter of your inserted
flash drive. This can be checked easily by opening “Computer” or “My Computer”.
Once the correct drive is selected, you must then select the blue folder icon
and navigate to the Google Chrome OS image file in the browser window that
pops up. If you have successfully selected the correct image it will show up in
the address bar to the left of the open source icon.
8. Double check the drive letter of your flash drive and then select “Write”
after making sure. A warning will pop up indicating your drive may malfunction if
you happen to select the wrong one, dismiss the warning message and the
program should begin writing a bootable image to your flash drive.
9. When the program has finished writing the image and displays “Done” in the
bottom left corner you may then remove the flash drive and close the program.
10. Reboot the machine and choose the USB thumb drive you just created as the
boot partition. The computer will then boot into the Google Chrome OS Flow
11. The first time you login into the OS you will need to login using a common
login name and password. The Login screen looks like the image at the top left,
with the Google Chrome and Flow logos clearly evident.
After the OS has started up simply login to a Gmail or email account. After you
have successfully logged in, reboot the computer (press power off) and complete
the steps again to boot into the Google Chrome OS. You should then be able to
login to the OS using your Gmail account and password once it boots up. Netbook
users are less fortunate, there is currently a bug preventing login – so just login
using the “facepunch” info. All personal account information will be stored
however so you won’t have to keep logging in after reboots.
Congratulations, now you know where to download Google Chrome OS and how to

5. What is the purpose of Chrome OS?:
ANSWER: Since Chrome OS targets computer users who spend most of their time on
the Internet, it is mainly aweb browser with no ability to run applications. It relies
on Internet applications (or Web apps) used in the web browser to accomplish tasks such
as word processing and media viewing, as well as online storage for storing most files.
6. What is the purpose of the Chrome web app store?
ANSWER: lets you publish apps where Google Chrome users can easily find them.
The store's primary purpose is to help Chrome users find apps. It does this by
supporting search, by providing browsable categories of apps, and by displaying lists
of various kinds, both curated and autogenerated. User ratings and reviews are used
to rank apps.

8. Are there any malware specific to Chrome OS?
Google touts the Chrome OS as being free from traditional security concerns like malware, but it's
still vulnerable to entirely different kinds of attacks, two researchers from the firm WhiteHat
Security told Black Hat attendees here today.
"It's more similar to mobile devices and apps, where to get more out of the device you're going to
need to install extensions," he said. "Mobile bugs are being sold for 20 to 30 percent more than
desktop bugs because if you own somebody's phone you own their life."
"We actually saw an extension in the Chrome Web Store called Cookie Stealer that did precisely that.
But hey, it had the checkmark next to it that it was verified safe and secure," Johansen quipped.
Chrome OS devices don't use internal hard drives, eliminating the possibility of persistent
malware infections and data theft.
Google's policy of abstaining from reviews of extensions that are uploaded to the
company's Web store also pose a problem by allowing clearly malicious extensions to be
posted without any review or sanity checking.
9. How would you best protect a PC running Chrome OS.
The most effective form of protection is to ensure that the software on your
computer is up-to-date, and that the latest security firmware is on your machine.
Simply put, system updates prevent new malware from attacking your computer.
The sporadic nature of traditional operating systems with many software
components from many vendors can become difficult to use because of the
different apparatuses and interfaces. In addition to this, the majority of users will
not immediately download any given update. One of the best aspects about
Chrome OS is the fact that every time the computer turns on, it is completely
updated. This is because it is constantly connected to the web, a feature that
gives Google the ability to patch the security features of its operating system on
On any given Chromebook, each web page and application that users visit is
housed within a separate “sandbox”. This is a restricted environment that
prevents infected pages from affecting the other tabs or pages you are running
on your computer. This contains any potential threats, isolating them from
sensitive personal data and information. This principle is applied to Google’s
server on a large scale as well. Any infected web apps can be isolated on
Google’s servers and individually dealt with to ensure that the smallest number of
users are affected by any given security threat.
If malware were to infect your computer, escaping the sandbox, a device running
Chrome OS would still be protected. Every time your computer boots up, the
system runs a self-check called “Verified Boot”. This feature can detect if your
system has been corrupted in any way and actively fix your computer without any
