Which statement best describes cloud computing and its advantage for students?

• A. Cloud computing stores data only on local devices; advantage: faster hardware.
• B. Cloud computing is a marketing term with no technical meaning; advantage: none.
• C. Cloud computing is a security protocol for email; advantage: better filters.
• D. Cloud computing delivers computing resources over the internet; advantage: access from anywhere and scalable storage.

Answer: (D)

The concept being tested is what cloud computing is and why it matters for students. Cloud computing means providing computing resources—such as servers, storage, and software—as services over the internet, rather than having everything run and stored on a single device. The statement that best describes this idea and its benefit says that computing resources are delivered over the internet, with the advantage of access from anywhere and scalable storage. For students, this translates to being able to use apps and save files from any device with internet access, collaborate easily with peers, and adjust how much storage or computing power you need without buying new hardware. The other descriptions miss the point: storing data only on local devices ignores the remote access and flexibility of cloud services; calling it just a marketing term ignores the real technical service model; and framing it as a security protocol confuses cloud services with security features.
