7 Move Over Microsoft, Google Chrome OS Is Here Google has revealed its hotly anticipated operating system  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.

8 Move Over Microsoft, Google Chrome OS Is Here Google has revealed its hotly anticipated operating system  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.

9  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. Move Over Microsoft, Google Chrome OS Is Here

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

13 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 handle storage 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 panel window for videos. Printer support is also coming, but Google said it would have more details on that at a later date. The focus for now is to get the OS ready for launch next year and netbooks are the only target devices at the time. Google will work closely with hardware manufacturers and all the products that will ship with Chrome OS next year will be certified by the company. However, the devices aren't exactly the netbooks we have today, Google wants them to have larger screens and a full-sized keyboard. Another interesting requirement is that all devices will be required to have only SSD drives. The focus for now is to get the product on the market and other form-factors may be supported, but after Page 1 Copyright (c) Softpedia. All rights reserved.

14 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.

15 People want to get their 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.

16 browser, is an open-source project. Windows XP being the favorite OS). But unlike the open-source community, Google has the necessary financial resources and connections to steal territory away from Microsoft. "Speed, simplicity and security are the key aspects of Google Chrome OS. We're designing the OS to be fast and lightweight, to start up and get you onto the web in a few seconds. The user interface is minimal to stay out of your way, and most of the user experience takes place on the web. And as we did for the Google Chrome browser, we are going back to the basics and completely redesigning the underlying security architecture of the OS so that users don't have to deal with viruses, malware and security updates. It should just work," Pichai and Upson added. Google Chrome OS will be tailored to work with both x86 processors but also ARM CPUs. The Mountain View search giant explained the software architecture of the new platform as "Google Chrome running within a new windowing system on top of a Linux kernel." In this regard, Google already benefits from a mature and fully evolved platform development ecosystem. The company explained that applications wouldn't be developed for the Google Chrome OS but for the Internet. Chrome OS will do nothing more than run the Chrome browser, which in its turn will run Cloud applications. "All web-based applications will automatically work and new applications can be written using your favorite web technologies. And of course, these apps will run not only on Google Chrome OS, but on any standards-based browser on Windows, Mac and Linux thereby giving developers the largest user base of any platform," Pichai and Upson promised.

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.

17 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.

18 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 like Apple’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.

19 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:

20 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.

21 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.

23 Google Attacks on Microsoft Google plans to attack Microsoft's core business by taking on the software giant's globally dominant Windows operating system for personal computers. Google Chrome Operating System, the new software will be in netbooks in the second half of 2010.

24 Microsoft OS Share on PC ~90% PCs using Microsoft’s OS Google is planning to capture Microsoft Share of 90%

25 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.

26 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.

27 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.

28 Google Chrome OS Chromium OS Open Source Project Must be built from source No Auto-Update Can be modified and assumed will be adapted to wide range of hardware Everything can and ‘will’ change by Q4 shipping of OEM devices with Google Chrome OS Supported by Open Source Community Is the official Google released OS Will only be installed on partner OEM hardware OEM hardware will provide enhanced performance and security Auto-Update enabled Verified ‘secure’ boot using firmware signature checks Easy recovery firmware feature Google stores backup encryption keys on cloud Supported by Google and Partners

31 Time-sharing/Multitasking Time-sharing between process A and process B 31 (Fig. 3.6)

32 Context (Process State) Snapshot of current status of a process A process identifier, or PID 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 32

33 Scheduler Determines which processes should be considered for execution based on some priorities or concerns Using process table for administration Process table Ready or waiting Priority Non-scheduling information: memory pages, etc. 33

34 Context Switch (process switch) 1. Get an interrupt from timer 2. Go to the interrupt handler a. Save the context of process A b. Find a process ready to run (Assume that is process B) c. Load the context of process B 3. Start (continue) process B 34

35 35 Conditions for Deadlock 1. Competition for non-sharable resources 2. Resources requested on a partial basis 3. Allocated resources cannot be forcibly retrieved 4. Circular wait Remove any one of the conditions can resolve the deadlock.
