3. Such problems thus need computing resources (say processing power of the order of teraflops, secure dependable networks and storage) often for which even a supercomputer does not suffice.

6. Grid resources may be owned and managed by multiple organizations often heterogeneous (platforms, operating systems) and geographically dispersed in nature.

22. A virtual organization (VO) is a dynamic group of individuals, groups, or organizations who define the conditions and rules (business objectives and policies) for sharing resources.
23. Although the resources in a grid might be in separate administrative domains, they are made available as virtual local resources to any node on the grid.
24. Dynamically collect resources from different providers based upon the users’ needs or urgency and the priority of the problem.
25. Identify problems, linking them to required resources or service providers, and automatically resolve them.

46. STANDARIZATION -to allow interoperability between different products and implementations.Open Grid Service Infrastructure (OGSI) standard . WSRF (Web Services Resource Framework) standard that enables Web services integration within Grid Architecture. This allows Grid Developers to take advantage of standard message formats and communication mechanisms such as HTTP and XML for communicating between heterogeneous components and architectures.
