Transcript of "Chromium OS"

  1. 1. Chromium OS BY : AATMAN KOTHARI
  2. 2. Introduction• Google Chrome OS is a Linux-based operating system designed by Google to work exclusively with web applications• Google 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.• Click here for a short introductory video.
  3. 3. User interface► Chromium OS uses the new chrome: //newtab page found in GoogleChrome to open web apps. Compared to prior builds, this replaces theapplications page.► Chromium OS provides a clock, battery indicator and networkstatus indicator.► The Ctrl+Alt+/ key combination toggles a keyboard overlay that showsthe function of all the shortcut keys used in Chromium, including taskand memory managers also found in the Chrome browser, and acommand-line interface that accepts common Linux commands.
  4. 4. Remote application access and virtual desktop access• In June 2010, Google software engineer Gary Kačmarčík wrote that Chrome OS will access remote applications through a technology unofficially called "Chromoting", which would resemble Microsofts Remote Desktop Connection.• The name has since been changed to "Chrome Remote Desktop", and is "probably closer to running an application via Remote Desktop Services or by first connecting to a host machine by using RDP or VNC". Initial roll-outs of Chrome-OS laptops (Chromebooks) indicate an interest in enabling users to access virtual desktops.
  5. 5. <> 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.MEDIA PLAYER , FILEMANAGER <> 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.
  6. 6. Features and working PRINTING LINK HANDLING• Google Cloud Print is Googles proposed • Chrome OS was designed with the intention of having solution to help any application on any device to user documents and files stored on online servers. print on any printer. While the cloud provides However, both Chrome OS and the Chrome browser virtually any connected device with information have unresolved decisions regarding handling specific access, the task of "developing and maintaining file type’s offline. For example, if a JPEG is opened print subsystems for every combination of from a local storage device, should a specific Web application be automatically opened to view it, and if hardware and operating system – from desktops so, which one? Similarly, if a user clicks on a .doc file, to netbooks to mobile devices – simply isnt which website should open: Microsoft Office Live, feasible. "However, the cloud service would Gview, or a previewing utility? The project director at entail installing a piece of software, called that time, Matthew Papakipos, noted that Windows a proxy, as part of Chrome OS. The proxy would developers have faced the same fundamental register the printer with the service, manage the problem: "QuickTime is fighting with Windows Media print jobs, provide the printer driver Player, which is fighting with Chrome." As the number functionality, and give status alerts for each job. of Web applications increases, the same problem arises.
  7. 7. Security• In March 2010, Google software security engineer Will Drewry discussed Chrome OS security. Drewry described Chrome OS as a "hardened" operating system featuring auto-updating and sandbox features that will reduce malware exposure. He said that Chrome OS netbooks will be shipped with Trusted Platform Module (TPM), and include both a "trusted bootpath" and a physical switch under the battery compartment that actuates a developer mode. That mode drops some specialized security functions but increases developer flexibility. Drewry also emphasized that the open source nature of the operating system will contribute greatly to its security by allowing constant developer feedback.• At a December 2010 press conference, Google claimed that Chrome OS would be the most secure consumer operating system due in part to a verified boot ability, in which the initial boot code, stored in read-only memory, checks for system compromises.
  8. 8. ArchitectureIn preliminary design documents, Google describes a three-tierarchitecture: firmware, web browser and window manager, and system-levelsoftware and userland services.• 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. 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.
  9. 9. Versions:• ChromiumOS Cherry (4 December 2009) → ChromiumOS Flow (15 February 2010)• ChromiumOS Zero (9 December 2009) → ChromiumOS Vanilla (15 March 2011)
  10. 10. History of Chrome OS• Google developers began coding the operating system in 2009, inspired by the growing popularity and lower power consumption of netbooks and the focus of these small laptops on Internet access.• Matthew Papakipos, former engineering director for the Chrome OS project, put three machines in his house and found himself logging in for brief sessions: to make a single search query or send a short email.• At a November 19, 2009 news conference, Sundar Pichai, demonstrated an early version of the operating system
  11. 11. • At the conference, the operating system booted up in 7 seconds, a time Google said it would work to reduce.• On January 25, 2010, Google posted notes, images and a video of a conceptual design showing how a Chrome OS user interface might look on a tablet computer with a 5–10 inch screen.• 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.• On March 16, 2011, several changes to Chromium OS were made which indicate the development of a tablet version of Google Chrome OS.
  12. 12. ChromeBook and ChromeBox• Books are the laptops , tablets running chrome os and desktops running chrome os are called boxes.• On May 11, 2011 at its Google I/O developer conference, Google announced that the first two commercially available laptops incorporating Chrome OS would be manufactured by Acer Inc. and Samsung Electronics Co., with a retail price beginning at $349 (Rs. 18000 approx.)• Google claimed an eight-second bootup time and eight-hour operation on one battery charge, and said that the Chromebooks would require no virus protection.
  13. 13. • Models equipped with 3G connectivity receive 100 megabytes of wireless data per month, free for two years, with an additional gigabyte at $20 per month.• On May 29, 2012, Google and Samsung introduced the Second- Generation Chromebook and a new compact desktop Chromebox, which was said to be a clone of the Apple Mac Mini.
  14. 14. Relation to Android
  15. 15. • Googles successive introduction of the popular Android and Google Chrome OS has put the company behind two open source, client- based operating systems• Steve Ballmer accused Google of not being able to make up its mind.• Sergey Brin suggested that the two systems "will likely converge over time.”• Sergey Brin addressed the question by saying that owning two promising OSs was a problem that most companies would love to face".
  16. 16. 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.
