What does cloud computing primarily involve?

• A. Delivering computing resources over the internet.
• B. Storing data on local hard drives only.
• C. Running all software on personal devices.
• D. Using only on-premises servers.

Answer: (A)

Cloud computing is about delivering computing resources—like servers, storage, databases, and software—over the Internet so you can access and use them without owning or managing the physical hardware. This setup lets you scale resources up or down as needed and pay only for what you use, from anywhere you have online access. Storing data on local hard drives only is limited to a single device or location and doesn’t provide the on-demand, scalable access that cloud services offer. Running all software on personal devices ignores the benefits of centralized, remotely hosted applications. Using only on-premises servers reflects traditional IT infrastructure rather than the internet-based delivery model that defines cloud computing.
