Move Over Microsoft, Google Chrome OS Is Here

Google has revealed its hotly anticipated operating system

Google has just unveiled its hugely anticipated, web-based operating system,

Google Chrome OS.

Google hasn't actually launched the operating system, but it has released the

source code in its current state for developers to have a chance to start

working on it. From now on, the code will remain open for third-party

Google hasn't actually launched the operating system, but it has released the

source code in its current state for developers to have a chance to start

working on it. From now on, the code will remain open for third-party

developers to build and modify.

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.





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 its

browser 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.

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 itintended 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 handle

storage devices like cameras or SD cards.

When a storage device is plugged into the machine a list of thefiles 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 panel

window for videos. Printer support is also coming, but Google said it wouldhave 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 lessmemory-intensive, enabling users to access the Web in a few seconds.

The new system is designed to work with ARM and x86 chips, the mainchip architectures in use in the market. Microsoft has previously said it wouldnot support PCs running on ARM chips, allowing Google an opportunity toinfiltrate that segment.

Google Chrome OS features:



Features

Speedy boot up, as fast as three seconds: A Chrome OSdevice 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 bespecific. One of the primary reasons for this is to speed upboot time. With no local applications and limitedhardware, the device doesn't need to run through longchecklist looking for devices and drivers, loading

programs into resident memory and so on. It should turnon like a television, flip a switch and the within threeseconds browser should be available, showing the mostrecent 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 requirenothing 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. Userdata 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 MicrosoftOffice 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 thecompany'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 forboth popular net book CPUs.

The application menu

As new web applications come online tweaked for ChromeOS, Chrome OS will showcase them on a permanent tab itnow calls the application menu. This will help users findnew applications. Developers with new apps will find thisan easier method to showcase them, too. Any webapplication that runs in a standards compliant browsershould work on a Chrome OS device. But Chrome OS isfocused on supporting new protocols such as HTML 5, which, among other improvements, natively supports richmedia.

Register values, Program Counter value

The memory space, I/O, files for the process Can be saved and resumed as if the process is not

interrupted

Another meaning: execution state of the process Ready: ready for execution Waiting: waiting for some I/O

Complete: finished process
