WHAT IS A WEB OS?
A Web OS is a web-based app (generally powered by either AJAX or Flash technologies) that emulates the application capabilities of an operating system.
It’s basically a virtual desktop that gives you communication tools (like email and instant messaging), productivity tools like word processing, and ability to play games and any other application that you’d find on a typical OS like Microsoft Windows.
What is Cloud Computing?
Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network (typically the Internet).
HOW DOES IT WORK?
Web Operating System allows you to access applications stored not on your computer, but on the Web
The applications exist wholly or in part on Web servers within a particular provider network. When you save information in an application, you might not store it on your computer. Instead, you save the information to databases connected to the Internet.
Some Web operating systems also give you the option to save information to your local hard disk drive. It can access web applications and data from any device connected to the Internet
The user can access the Web OS on one computer, create a document, save the work and then access it again later using a completely different machine. Web operating systems offer users the benefit of accessibility
