Google Chrome OS (or Chromium OS) is an open source computer operating system created by Google with environment based on the Linux operating system and graphical user interface closely mimics the minimalist approach of the Google Chrome web browser and Litl webbook. Chrome OS is devoted to users who visit World Wide Web (WWW) most of the time who always access to web-based applications on the remote servers. Chrome OS relies heavily on could computing storage space, runs primarily on faster Solid-State Drive (SSD) with x86 or ARM processor powered system, with the Chrome-based web browser the only application installed on the device to interact with end-users.

Unlike traditional operating systems, Chrome OS doesn’t trust the applications you run. Each app is contained within a security sandbox making it harder for malware and viruses to infect your computer. Furthermore, Chrome OS barely trusts itself. Every time you restart your computer the operating system verifies the integrity of its code. If your system has been compromised, it is designed to fix itself with a reboot.

we are obsessed with speed. We are taking out every unnecessary process, optimizing many operations and running everything possible in parallel. This means you can go from turning on the computer to surfing the web in a few seconds. Our obsession with speed goes all the way down to the metal. We are specifying reference hardware components to create the fastest experience for Google Chrome OS.
