What is Chrome?
Chrome, developed and controlled by Google, may refer to either the
or the OS
that uses the latter web browser as its GUI. Chrome OS is intended for laptops (not intended for desktops), which Google markets under the name Chromebook. Just like Google's portable OS,
Android, it is also based on Linux.
Although the OS is
open source, users
only have access to personal files and no access to system files, especially
the kernel. Chrome OS mostly runs web
applications making it basically a thin client — except
with several (if not all) codecs, camera and daemons.
Running Chrome OS
(stable channel only) demands the user
to completely trust Google as it
controls all aspects of the OS
including and perhaps not limited to updates, which is perfect for users.
As a matter of fact, all applications are only accessible through the Chrome
Web Store and there is little to no risk of viruses
or other malware.
As of version 53 of the OS
released on September 2016, Google Chrome can run a
Play, which allows users
install and run Android apps.
Chrome OS has
a limited shell in user
mode by the name of crosh.
