What term best describes sets of computing resources that combine with software to form a server, allowing users to allocate only what they need?

• A. Virtualization
• B. Cloud computing
• C. Server farm
• D. Modular

Answer: (D)

Modular describes sets of computing resources that combine with software to form a server, allowing users to allocate only what they need. The idea is to build a server from interchangeable components—processing units, memory, storage, and networking—that can be added or removed as requirements change. This setup lets you provision exactly what you need, scaling by adding or removing modules rather than overbuilding. While virtualization, cloud provisioning, and a server farm touch other aspects of computing, modular focuses on assembling a server from configurable parts to tailor the resources to the actual demand.
