Which statement characterizes cloud computing?

• A. A local-only storage option on a single computer.
• B. A printing service for clinical documents.
• C. The use of computing resources delivered as a service over a network (typically the Internet).
• D. A protocol for streaming video.

Answer: (C)

Cloud computing means computing resources such as servers, storage, software, and networks provided to users as a service over a network, typically the Internet. This setup allows on-demand access, scalable resources, and management of the underlying infrastructure by the provider, so applications and data can be accessed from anywhere with minimal local hardware needs.

In a telehealth context, this enables hosting apps, storing patient data, and supporting video visits without maintaining extensive local infrastructure, with costs often based on usage. Local storage on a single computer isn’t network-delivered services; a printing service focuses on output rather than computing resources; and a streaming video protocol is about data transmission, not provisioning computing resources as a service.
