The cloud concept where computing resources are provided as services over the internet?

• A. Intranet
• B. Extranet
• C. BYOD
• D. Cloud

Answer: (D)

Cloud computing is the idea of providing computing resources as services over the internet. Instead of buying and maintaining servers and software yourself, you access infrastructure, platforms, or applications on demand from a provider, scale resources up or down as needed, and pay only for what you use. This on‑demand, internet‑based delivery is what the cloud represents, with common models like IaaS, PaaS, and SaaS. In contrast, an intranet is a private network inside an organization, an extranet extends that private network to outside partners under controlled access, and BYOD refers to letting employees use their own devices for work. Those don’t describe the service-based, internet-delivered nature of cloud computing.
