Which one of the following regarding cloud computing is true?

Question

BlackTom AI · Accepted Answer

Cloud services are delivered over a network, most commonly the public Internet, so an active network connection is required to access remote cloud resources.

1) Relevant knowledge points and concepts
- Cloud computing means storing, processing or providing applications and data on remote servers run by a provider rather than exclusively on a local device. 
- “Cloud” in everyday use implies remotely hosted services accessed over a network (typically the Internet). 
- Users generally do not have direct, full visibility into the provider’s internal access controls or exact physical storage locations unless the provider explicitly discloses them.

2) Step-by-step reasoning
- By definition, cloud resources are hosted off the user’s local machine. To use those remote resources (upload/download files, run cloud apps, access cloud-hosted services), data must travel between the user device and the provider’s servers.
- That communication requires network connectivity. For public cloud services that form the large majority of cloud use, that network is the Internet.
- Even when a provider offers caching or offline sync, the canonical cloud copy and many cloud functions still require reconnecting to the provider over the Internet to synchronize or perform server-side operations.

3) Calculations
- No numerical calculations apply.

4) Why the correct answer is correct
- Option d states cloud computing requires an internet connection. Because cloud services are remote and accessed over a network, an Internet connection (or equivalent network path to the cloud provider) is necessary to reach those remote servers. This matches the standard, practical meaning of cloud computing.

5) Why the other options are incorrect
- a: Users do not automatically “know exactly who has access”; providers control many access layers and users often rely on provider policies and tools rather than complete visibility. 
- b: Cloud computing is very popular and widely adopted; while security/stability are concerns, they have not prevented broad adoption. 
- c: Users typically cannot know the exact physical/geographical location of stored files; providers often distribute data across multiple data centers and may only offer region-level choices.

6) Conclusion
- Therefore the correct choice is d. Cloud computing requires an internet connection.
