What defines cloud computing?

Cloud computing is defined as a model where all programs and data are stored on centralized servers rather than on local devices. This allows users to access their data and applications over the internet from any location, using various devices such as computers, tablets, or smartphones. Centralized storage and processing enable seamless collaboration, flexible resource allocation, and cost-effectiveness, as users can scale resources according to their needs without the burden of maintaining physical infrastructure.

The other options do not accurately capture the essence of cloud computing. For instance, storing data on local devices focuses on traditional, on-premises data management without leveraging the advantages of remote access. A framework for data encryption might be a component of cloud security but does not encapsulate the broader concept of cloud computing itself. Lastly, a platform for desktop publishing is a specific application and does not relate to the overall infrastructure and utility that cloud computing represents. Therefore, the correct choice emphasizes the centralized model that defines cloud computing.
