WHAT IS GOOGLE CHROME OS ?

• Google Chrome OS is a operating system designed by Google to work exclusively with web applications.•Google Chrome OS is an open source, lightweight operating system that will initially be targeted at netbooks.•Speed, simplicity and security are the key aspects.•Google Chrome OS is initially intended for secondary devices like netbooks, not as a user's primary PC.

HISTORYHISTORY

• 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.

• For developing new OS they monitored the usage patterns of some 200 Chrome OS machines used by Google employees.

• On November 19, 2009, – Google released Chrome OS's source code as the

“Chromium OS project”.– Google demonstrated an early version of the

operating system.

• 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 PC with a 5-10 inch screen.

• In March 2010, Google indicated that they are developing two versions of the operating system, a consumer version and an enterprise version.

• In December 2010 Google showed off a development Google Chrome OS laptop that replaced the Caps Lock key with a dedicated search key.

HARDWARE SPECIFICATION

• Google Chrome OS code will only be supported by Google and its partners, and will only run on hardware designed for the purpose.

• Google Chrome OS will run on both x86 as well as ARM chips.

• While Chrome OS will support hard disk drives.• Google Chrome OS consumes one-sixtieth as

much drive space as Windows 7.

Cr-48 PROTOTYPE HARDWARE

• At a December 7, 2010 press briefing, Google announced the Cr-48 netbook, a piece of reference hardware created to test the Chrome OS operating system.

• The Cr-48 is intended for testing only, and will not be sold to the general public.

• operating system offers little functionality when the host device is not connected to the Internet.

User Interface

• The company demonstrated an offline version of Google Docs running on Chrome OS and announced a 3G plan that would give Chrome OS users 100MB of free data each month, with additional paid plans available from Verizon.

• About 60,000 Cr-48s were distributed to testers and reviewers in early December 2010. Reviews published about the Chrome OS running on the Cr-48 in mid-December 2010 indicated that while the project holds promise it still has some distance to go before being ready for market.

DRAWBACKS…

• The new operating system is designed to specifically target the Internet generation.

• it won't be as successful in the short term.• Since the new operating system is web-

centric, users are required to have anytime access to the Internet to maximize Chrome usage.

• The lack of offline support is a huge disadvantage

DRAWBACKS

• one will also need a reliable high speed Internet connection to run data-heavy applications or to perform multitasking.

• as many people still don't have 24/7 access to high speed Internet.

• The lack of Photoshop or another decent image editing application. It is Workable, but annoying is the track pad design.

• "met the basic requirements for Web surfing, gaming, and personal productivity, but falls short for more intensive tasks".

• “ It's decidedly not a full-fledged alternative to the general purpose computing environments that currently ship on netbooks".

• “most of Chrome OS's advantages "can be found in other software environments without having to sacrifice native applications".

“ Google has a lot of work to do, but Chrome OS makes a lot of sense and if Google does not shoot itself in the foot, it could light the way to how mainstream computing will look like 5 or 10 years from now."
