NEW YORK (

TheStreet

) -- At a

developers' conference

in San Francisco Tuesday,

Google

(GOOG) - Get Report

demonstrated an updated version of its Chrome operating system and promised to open a Chrome Web store.

The Chrome Internet-based operating software will power devices like notebooks and netbooks, which are expected to be sold by

Verizon

(VZ) - Get Report

with a data plan that starts at $10 a month. Google said the Chrome Web App store would open Tuesday and will feature programs from

Amazon

(AMZN) - Get Report

and

The New York Times

(NYT) - Get Report

.

The announcements arrive a year after Google first outlined its

concept of an open OS

, an extension of its Chrome browser. Google said it designed the Chrome OS for utility and speed by putting the software on the Internet and making it accessible from low-powered machines using high-speed WiFi connections or Verizon's 3G.

Via any Chrome device, users will be able to connect to their virtual computer and resume their Internet activities where they left off. Google's Chrome effort takes the opposite approach of computer software makers like

Microsoft

(MSFT) - Get Report

and

Apple

(AAPL) - Get Report

, which load machines with powerful and often cumbersome applications.

One application Google expects to have available is Cloud Printing, a system that presumably allows you to pick a printer anywhere to print your documents.

Google's Chrome requires users to have constant Internet contact and great faith in the security and performance of information and applications available online only.

Google says the first notebooks will be made by

Acer

and

Samsung

and are expected to be available mid-year 2011.
