Google Chrome OS is the Linux based cloud OS for the respective Chromebooks but you can also use the Chromium OS on any computer you want. However, Chromium OS we used didn’t seem to be official but for Jolicloud OS, the rival to Chrome OS, it is kind of neater that way as we’re able to use the web edition of Jolicloud OS on the browser that brings the similar features. The only difference is that web edition is not the online operating system itself but rather the service that brings similar features to using Jolicloud OS itself. Google Drive is the upgrade from Google Docs with improved and new features to the existing apps such as doing spreadsheet, presentation, word processing and even more. It is recently available for Chrome OS and Chrome Web Store and we can call Google Drive as another cloud storage service and the rival to other cloud storage services as we know and use.
