Abstract

WebOS (Web predicated ) is an incipient form of Operating Systems. You can utilize your desktop as a virtual desktop on the web, accessible via a browser, with multiple integrated built-in applications that sanction the utilizer to facilely manage and organize her data from any location. Desktop on web can be designated as WEBtop. An incipient form of computing kenned as cloud computing can avail us to design web predicated operating systems for future. This paper commences with a exordium of WebOS and its benefits. The Web OS transcends rudimental desktop functionality. It withal includes many of a traditional OS’s capabilities, including a file system, file management, and productivity and communications applications. In the case with Web-predicated applications, the Web OS functions across platforms from any contrivance with Internet access. The Web OSs that run on the browser are platform-independent, since browsers are built to work across different operating systems. As users become more comfortable working over the Web, the Web OS could become more popular. For this paper, we have reviewed some most intriguing WebOS available nowadays and endeavored to provide a detailed description of their features. We have identified some parameters as comparison criteria among them.

Keywords: Web OS, WebTop, Cloud Computing, Web Based Applications.

1. Introduction of California, Berkeley in 1996 (that is now perpetuating at Duke University), which The web operating system is evolving as a describes it this way: "WebOS provides form at a rapid pace, promising to liberate us rudimental operating systems from Windows once and for all. If you accommodations needed to build optate to take the desktop to your web applications that are geographically browser, one contender is well on the way to distributed, highly available, incrementally making it possible. Web Operating Systems scalable, and dynamically reconfiguring." (WebOS) is: “A software platform that interacts with the utilizer through a web Now you can cerebrate WebOS as a virtual browser and does not depend on any desktop on the web, accessible via a particular local operating system.”, with multiple integrated built-in operating systems are withal commonly applications that sanction the userto facilely referred to as Web desktops or WEBTOPS. manage and organize her data from any "A web desktop or webtop is a network location.

So any applications into a web predicated work accommodation or application that needed space. It is a virtual desktop on the web, to be integrated in future, can be developed running in a web browser as software.
