Move Over Microsoft, Google Chrome OS Is Here

Google has revealed its hotly anticipated operating system

Google stated when it first revealed that it was working on its very own OS, Chrome OS will be completely web-based.



There will be no native apps for it, even the tools that will be built by Google and bundled with the OS will be web apps.

In a simplified view, Chrome OS is just a specialized version of itsbrowser Chrome running on top of an optimized Linux kernel.

There have been a number of modifications done to Chrome in order to make it function as a full-blown operating system. One of the things Google has introduced consists of persistent application tabs, which will always be available to the user and are fully customizable.



Apps can also be run in a "panel" that is a persistent light-weight window, which sits on top of the browser designed for apps like instant messengers.

This way, users can log into a Chrome OS machine with their accounts and get their own desktop, applications and customizations just like using their own machines.


One of the biggest questions that popped up when Google announced the OS was how it intended to handle?

All of the various hardware peripherals available. Now, Google has announced that most common types of hardware will be supported. All input devices will have built-in support and Chrome OS will also handlestorage devices like cameras or SD cards.

When a storage device is plugged into the machine a list of the files and directories on the device will be available in a new tab in Chrome.

Users will then be able to view common media files like photos, music files or videos either in a new tab, in the case of photos, or in a panelwindow for videos. Printer support is also coming, but Google said it would have more details on that at a later date.

Windows Killer: Google Chrome OS Drops in 2010

With Linux at the core. It turns out that all those rumours' of an operating system from Google to go against Windows have managed to come true.

And ultimately to offer a platform designed to rival Windows. For this, Google has turned to the all-time anti-Windows favourite platform, Linux. At the same time, the search giant's focus with the new OS will be its Chrome browser.

• People want to get their email instantly, without wasting time waiting for their computers to boot and browsers to start up. They want their computers to always run fast.

•They want their data to be accessible to them wherever they are and not have to worry about losing their computer or forgetting to back up files.

•The promise with Google Chrome OS is that the focus will be on delivering a platform that will integrate seamlessly with hardware and software, requiring minimal user intervention.

when it comes down to the setting up and updating processes. Users "don't want to spend hours configuring their computers to work with every new piece of hardware, or have to worry about constant software updates. And any time our users have a better computing experience, Google benefits as well by having happier users who are more likely to spend time on the Internet.

What is Google Chrome OS?

The Google Chrome OS is envisioned to be a lightweight operating system that promises to start up and get users on the Internet in a few seconds. The Official Google Blog said the OS will target net books first when it comes out next year, and will be made available for enterprise computing solutions in succeeding releases of the software.

Here is what’s at the core of the Google Chrome OS:

• The operating system will be free and open source, and built on top of a Linux kernel.It will run on both x86 and ARM chips.• Applications that run on Google Chrome OS will do so through any standard browser likeApple’s Safari, Mozilla’s Firefox, among others.• Google Chrome OS is separate from Android (Google’s OS for phones, hand-held devices,and set-top boxes).• OEM manufacturers like Acer, Adobe, Asus, Free scale, Hewlett-Packard, Lenovo, Qualcomm,Texas Instruments, and Toshiba are working with Google to build devices installed with the OS.

Fast & light weight : The new Chrome OS is expected to work well with many of the company's popular software applications. It will be fast and less memory-intensive, enabling users to access the Web in a few seconds.

The new system is designed to work with ARM and x86 chips, the main chip architectures in use in the market. Microsoft has previously said it would not support PCs running on ARM chips, allowing Google an opportunity to infiltrate that segment.

Google Chrome OS features:

Features Speedy boot up, as fast as three seconds: A

Chrome OS device will not store any applications on the device itself. The only applications it will use are those that can be run from the cloud in a browser, the Chrome browser, to be specific. One of the primary reasons for this is to speed up boot time. With no local applications and limited hardware, the device doesn't need to run through long checklist looking for devices and drivers, loading programs into resident memory and so on. It should turn on like a television, flip a switch and the within three seconds browser should be available, showing the most recent browser windows.

Security by default: The portion of the operating system needed to operate the device will reside in a read only section of memory. The rest of the operating system is integrated with the Chrome browser and, like the browser, security updates require nothing more than a reboot. Chrome OS can run multiple web applications in multiple tabs and each one is locked down from all others, so one web app can't lead to exposure in another. User data stored on the device, which is minimal, is encrypted. User data is limited to items such as user preferences. All other data will be stored in the cloud.

A surprising way to support Microsoft Office

Chrome OS would handle Office documents via Microsoft Office Live, the free web app version of Office available to Windows Live users. If a user clicks on an .xls document, Chrome launches Excel via the browser in Office Live.

Google Chrome OS Cost

Google did not say how much it would charge for the operating system (OS), but Enderle expects Google to charge

at most a nominal fee or make it free, saying the company's business model has been to earn revenue from connecting applications or advertising.

Support for both x86 and ARM architectures: Google promises that it will be writing native

code for both popular net book CPUs.

The application menu As new web applications come online tweaked

for Chrome OS, Chrome OS will showcase them on a permanent tab it now calls the application menu. This will help users find new applications. Developers with new apps will find this an easier method to showcase them, too. Any web application that runs in a standards compliant browser should work on a Chrome OS device. But Chrome OS is focused on supporting new protocols such as HTML 5, which, among other improvements, natively supports rich media.
