Chrome OS
By : NIREESH KUMAR
IntroductionGoogle Chrome OS is a Linux-based operating system designed
by Google to work exclusively with web applicationsGoogle announced the operating system on July 7, 2009 and made
it an open source project, called Chromium OS, in November, 2009.
Since Google Chrome OS is aimed at users who spend most of their computer time on the Web, the major application on the device is a browser incorporating a media player and a file manager.
HISTORY OF CHROME OS
• Google announced Chrome OS on July 7, 2009, conceiving it as an operating system in which both applications and user data reside in the cloud.
• On November 19, 2009, Google released Chrome OS's source code as the Chromium OS project.
• Google Chrome OS code is only supported by Google and its partners and only runs on hardware designed for the purpose.
USER INTERFACE
Minimal screen space by combining applications and standard
Web pages into a single tab strip, rather than separating the two.
Handled with "panels": floating windows that dock to the bottom
of the screen for tasks like chat and music players. Google Chrome OS would follow the Chrome browser's
practice of leveraging HTML5’s offline modes, background
processing, and notifications.
Media Player , file manager Google integrates a media player into both Chrome OS and the Chrome browser, enabling users to play back MP3s, view JPEGs, and handle other multimedia files while offline. Chrome OS also includes an integrated file manager resembling those found on other operating systems, with the ability to display folders and their associated files, as well as preview and manage file contents using a variety of Web applications, including Google Docs.

FEATURES AND WORKING
Printing Google Cloud Print is Google's proposed solution to help any
application on any device to print on any printer.
Link Handling Chrome OS was designed with the intention of having user documents
and files stored on online servers. However, both Chrome OS and the Chrome browser have unresolved decisions regarding handling specific file type’s offline.
ARCHITECTURE
Google describes a three-tier architecture: • Firmware, web browser • System-level software and userland services • Window manager
The firmware contributes to fast boot time by not digging into for hardware, such as floppy disk drives, that are no longer common on computers, especially netbooks. 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.
VERSIONS• ChromiumOS Cherry (4 December 2009) • ChromiumOS Flow (15 February 2010)
• ChromiumOS Zero (9 December 2009)
• ChromiumOS Vanilla (15 March 2011)
Relation to Android
• Google's successive introduction of the popular Android and
Google Chrome OS has put the company behind two open
source, client-based operating systems
• Steven Levy wrote that "the dissonance between the two
systems was apparent" at the 2011 Google I/O developer
conference.
• Sergey Brin suggested that the two systems "will likely
converge over time.”
Advantages :1.Fast booting.2.Simple , intuitive , beautiful.3.Less hassle than traditional operating systems.
Disadvantages :1.More internet expenditure.2.Some functionalities disable when offline.3.Less storage memory.
CONCLUSION Google’s Chrome OS may or may not make it, but the attempt
shows how far the computer industry has come from a bulky PC chained to a desk by its power cord and Ethernet cable. The computer is evolving from those dinosaurs to a smaller, mobile model that is always connected to the web. The iPhone brought us apps that are lightweight so users don’t get bogged down by smaller processors and slower wireless web connections on mobile devices. Google’s Chrome OS attempts to keep that speed, while preserving a platform for Google to make money through advertising.
