Using Linux as a base, Google designed Chrome OS to work exclusively with web applications. The user interface takes a minimalist approach, which greatly resembles the Google Chrome web browser. Chrome OS was built for people who spend a majority, if not all, of their time on the computer connected to the internet. The only application that comes installed on Chrome OS is a special Google Chrome web browser with an integrated media player and file manager. All other applications are accessed by adding apps from the Google Chrome Web Store. Since Chrome OS relies entirely on Google's web apps and access to Google's services, it is highly recommended that you connect to the internet to optimize your Chrome OS experience.
With a purchase of a Chromebook, you will receive a 2-year subscription to 100GB of Google Drive storage. Once your data is uploaded to the Cloud, you can easily access it anywhere you have Internet.
