Final answer:
Statements A, C, and D about cloud computing and grid computing are true. Cloud and grid computing are both scalable, cloud computing is potentially more eco-friendly, and cloud computing encompasses elements of grid computing, utility computing, and thin clients.
Step-by-step explanation:
Among the statements provided regarding cloud computing and grid computing, there are a few that are true:
- A) Both cloud computing and grid computing are scalable. This means that resources can be added or removed to match the demand, allowing for efficient use of resources.
- C) Cloud computing may be more environmentally friendly than grid computing. This is because cloud providers can optimize the usage of hardware to maximize energy efficiency, whereas grid computing often involves distributed computing which may not always be optimized for energy use.
- D) Cloud computing does indeed include aspects of grid computing and utility computing. It also uses the concept of thin clients, which are computers with minimal processing power that rely on a central server.
There is no evidence that statement B is true, as grid computing typically involves large-scale tasks rather than storing very small data objects like 1 byte in size.
