18. Benefits of WebOS
Enabling mobile work - G.host allows the growing number of mobile workers to take their desktop layout, applications and essential files wherever they go, regardless of the computer they use to access the web.
Overcoming the firewall - Being stuck behind the corporate firewall, or facing network restrictions at schools, offices and libraries can be frustrating. In principle, G.ho.st allows users to access what has until now been unaccessible.
Effective file management - Rather than having your data scattered about the web with a vast range of services, the web OS promises to make it easy to store, sort and access all of your files wherever you go from a single networked tool.

19. Empowering non-PC owners - While some of us take having a laptop for granted, there are others whose main point of access is through Internet cafes or public libraries. For these people, having to 'start from scratch' every time can prove very tiresome. With a web-mobilized operating system, this ceases to be an issue
Integrating services - Through effective partnerships with existing service providers, which G.ho.st has been very proactive about forming - it is possible to introduce such benefits as a single sign-on process, taking the pain out of logging in and out of multiple accounts every time you go online

20. Security and Authentication
WebOS Security model
Step1 : users transfer some portion of their access rights to webOS server when attempting to access a remote resource
Step 2: WebOS servers communicate using SSL
Step 3: The remote server checks if the proper credentials are held in local ACL’s

21. Applications Internet chat Remote Compute Engine
Wide area Cooperative Cache
Internet Weather
Cloud storage
Cloud gaming
Software testing (across different platform)

22. 1 Occupies little hard disk space
Advantages
1 Occupies little hard disk space
2 Occupy small CPU resources
3 Can be obtained at any OS with web browser
Disadvantages
1 easy to be hacked
2 can not be obtained offline
3 can not program on the local hardware so USB disk
and CDROM can not be used.
4 more bandwidth is needed for multiple programs to run simultaneously
5 server crashes.

23. Conclusion
Extending server functionality onto client machines allows for more flexible implementation of name resolution, load balancing, and fault tolerance.
Simplifying the implementation of a number of wide area applications.
Web os is a new technology, it still has its share of problems. But it has a great future!
