NEW GOOGLE CHROME OPERATING SYSTEM

By | May 19, 2010

Google Chrome OS is a new operating system introduced by Android. Android was designed from the beginning to work across a variety of devices from phones to set-top boxes to netbooks. The CHROME OS is designed to achieve speed, simplicity and security. The CHROME OS is  fast and lightweight and takes very less time to  start up and browsing is also with great fast. The security architecture of the OS is tight  like linux  users don’t have to deal with viruses, malware and security updates. Google Chrome OS will run on both x86 as well as ARM chips and the software architecture is simple Google Chrome running within a new windowing system on top of a Linux kernel.

The Google chrome OS founder says It’s been an exciting nine months since we launched the Google Chrome browser. Already, over 30 million people use it regularly. We designed Google Chrome for people who live on the web searching for information, checking email, catching up on the news, shopping or just staying in touch with friends. However, the operating systems that browsers run on were designed in an era where there was no web. So today, we’re announcing a new project that’s a natural extension of Google Chrome the Google Chrome Operating System. It’s our attempt to re-think what operating systems should be.

On November 19, 2009 Sundar Pichai, the Google vice president overseeing Chrome, demonstrated an early version of the operating system, which included a desktop that closely resembled the Chrome browser. At the conference, the operating system booted up in seven seconds, a time Google said it would work to reduce. In March 2010 Google indicated that consideration is being given to developing two versions of the operating system, a consumer version and an enterprise version

The design would include the same basic layout as on netbooks, but with a touch interface; an onscreen qwerty keyboard in different layouts; large, square icons placed above the tabs; and panels placed along the bottom edge that could be opened with an upward dragging motion.

The Chromium OS alpha release includes an applications page, launched by a button in the upper-left corner of the screen. The page links to Google web applications, including Gmail, Google Apps, and YouTube, as well as other applications, including Yahoo! Mail, Pandora, Hulu, Facebook, and Twitter. Chromium currently also provides a calculator, clock, battery indicator, and network status indicator. The function key F12 brings up a multi-window view, with the option to open additional browser windows and switch between them. The F8 key toggles a keyboard overlay that shows the function of all the shortcut keys, including task and memory managers comparable to those found on the Chrome browser, and a command-line interface that accepts common Linux commands.

ARCHITECTURE OF CHROME OS

Chromium OS is an open source project based on 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.
