ChromeOS instance of Linux distribution
ChromeOS, sometimes styled as chromeOS and formerly styled as Chrome OS, is a Linux-based operating system developed and designed by Google. It is derived from the open-source ChromiumOS and uses the Google Chrome web browser as its principal user interface.
Google announced the project in July 2009, initially describing it as an operating system where applications and user data would reside in the cloud. ChromeOS was used primarily to run web applications.All ChromiumOS and ChromeOS versions support progressive web applications (such as Google Docs or Microsoft Office 365), as well as web browser extensions (which can resemble native applications). ChromeOS (but not ChromiumOS) from 2016 onwards can also run Android applications from Google Play. Since 2018, ChromiumOS/ChromeOS version 69 onwards also support Linux applications, which are executed in a lightweight virtual machine with a Debian Linux environment.The operating system is now usually evaluated in conjunction with the hardware that it runs on.Architecture
ChromeOS is built on top of the Linux kernel. Originally based on Ubuntu, its base was changed to Gentoo Linux in February 2010. For Project Crostini, as of ChromeOS 80, Debian 10 (Buster) is the default container base image. In preliminary design documents for the ChromiumOS open-source project, Google described a three-tier architecture: firmware, browser and window manager, and system-level software and userland services.
The firmware contributes to fast boot time by not probing for hardware, such as floppy disk drives, that are no longer common on computers, especially netbooks. The firmware also contributes to security by verifying each step in the boot process and incorporating system recovery.
System-level software includes the Linux kernel that has been patched to improve boot performance. Userland software has been trimmed to essentials, with management by Upstart, which can launch services in parallel, re-spawn crashed jobs, and defer services in the interest of faster booting.
The window manager handles user interaction with multiple client windows (much like other X window managers).
