INTRODUCTION

1.1PURPOSE
Open Web OS, formerly HP Web OS, Palm Web OS or simply Web OS, is a mobile operating system based on a Linux kernel, initially developed by Palm, which was later acquired by Hewlett-Packard .The official name is web OS, uncapitalised. But Web OS is also us.Palm launched Web OS in January 2009. Various versions of Web OS have been featured on several devices, including Pre, Pixy, and Veer phones and the HP Touchpad tablet.After the failure of the HP Touchpad and the proposed sale of the HP Personal Systems Group, HP announced plans to release an open source version of the Web OS platform, named Open Web OS. Code specific to the existing devices was released as Web OS Community Edition (CE), with support for the existing HP hardware. Open Web OS includes open source libraries designed to target a wider range of hardware.

1.2 BACKGROUND

Web operating system and web OS are met computing terms that refer to network services for Internet scale distributed computing, as in the Web OS Project at UC Berkeley, and the WOS Project. In both cases, the scale of the "web operating system" extends across the Internet, like the web. However, the terms web OS and web operating system have been employed more broadly and with far greater popularity in the context of "the web as in HTTP", and for many meanings ranging from singular systems to collections of systems. In April 2002, Tim O'Reilly spoke of "the emergent Internet operating system" as an open collection of Web services Common to uses for collections of systems, a web operating system is distinct from Internet operating systems in that it is independent of the traditional individual computer operating system. This conception of the system reflects an evolution of research in the field of operating systems into the increasingly minimized (for example, Tiny OS and Exokernel) and distributed (for example, Inferno), and for distributed systems increasingly defined in terms of the specification of their network protocols more than their implementations (for example, Plan9's 9P). In a usage referring to singular network services, a web operating system is another name for a WebTop. These services turn the desktop into a service that runs on the Internet[8] rather than on the local computer. As these services include a file system and application management system, they increasingly overlap with the functionality of a traditional desktop computer operating system. In a usage referring to desktop (or handheld) computer application environments, a web operating system is a traditional operating system that is focused on supporting Web applications themselves, or a desktop operating system solely providing Web access.[9][10][11] Systems like these also are known as kiosks. Palm launched Web OS in January 2009 as the successor to Palm OS. The first Web OS device was the original Palm Pre, released by Sprint in June 2009. The Palm Pixy followed. Upgraded "Plus" versions of both Pre and Pixy were released on Verizon and AT&T. In April 2010, HP acquired Palm; Web OS was described as a key asset and motivation for the purchase. The $1.2 billion acquisition finalized in June. HP indicated its intention to develop the Web OS platform for use in multiple new products, including smart phones, tablet computers and printers. In February 2011, HP announced that it would use Web OS as the universal platform for all its devices. However, HP also made the decision. That the Palm Pre, Palm Pixy, and the "Plus" revisions would not receive over-the-air updates to Web OS 2.0,despite a previous commitment to an upgrade "in coming months". HP announced several new Web OS devices, including the HP Veer and HP Pre 3 smart phones, running Web OS 2.2, and the HP Touchpad, a tablet computer released in July 2011 that runs Web OS 3.0. In March 2011, HP announced plans for a version of Web OS by the end of 2011 to run within Windows, and to be installed .on all HP...
