Which term describes the general concept of hosting multiple virtual machines on a single physical server, not tied to a specific product?

• A. Virtualization
• B. Virtual Server
• C. Vmware
• D. Virtual Memory Manager

Answer: (A)

Virtualization is the practice of abstracting and pooling hardware resources so you can run several independent operating systems on one physical machine. A hypervisor sits between the hardware and the guest VMs, allocating CPU, memory, storage, and network resources to each VM while keeping them isolated from one another. This enables server consolidation, easier management, and flexible provisioning.

The other terms aren’t the general concept: a virtual server can refer to a single virtual machine or a specific product name, not the broad idea. VMware is a company (and its products) rather than the concept itself. Virtual Memory Manager is about managing memory within a single operating system, not about hosting multiple VMs.
