Question

Quizplus · Accepted Answer

Utility computing is a service model in which the provider makes computing resources and infrastructure management available to the customer as needed and charges them for specific usage rather than a predetermined price or flat rate. Grid computing involves the integration of multiple computing resources to deliver a uniform service, while client/server computing refers to a distributed architecture in which tasks or workloads are divided between client and server devices. Autonomic computing involves the creation of self-managing systems that can adapt and learn on their own, but does not relate specifically to purchasing computing power as a service.
