Which statement is associated with virtualization?

• A. A single physical computer can support multiple operating systems that operate independently.
• B. It speeds up wireless communication
• C. It eliminates the need for storage
• D. It makes programs run faster on a single core

Answer: (A)

Virtualization is the ability to run multiple separate computing environments on one physical machine by using a virtualization layer, such as a hypervisor. The statement describes this idea: a single physical computer can host multiple operating systems that operate independently. Each operating system runs in its own virtual machine with its own virtual hardware, and the hypervisor allocates CPU, memory, storage, and networking to each VM while keeping them isolated from one another. This setup enables tasks like server consolidation, testing across different OS versions, and safe software experimentation without affecting other environments. The other options don’t fit virtualization. It’s not about speeding up wireless communication, which deals with networking protocols and signals. It doesn’t eliminate the need for storage—virtual machines still require disk space for their virtual hard drives. And virtualization isn’t about making programs run faster on a single core; it introduces some overhead and its benefits come from isolation and resource sharing across multiple environments rather than raw single-core speed.
