Define virtualization and give one example of its use in computing basics.

• A. Virtualization creates virtual versions of hardware resources or entire machines; example: running multiple operating systems on a single physical host.
• B. Virtualization refers to storing data in the cloud only.
• C. Virtualization is the process of physically dividing a server into multiple physical servers.
• D. Virtualization is a technique to increase CPU speed by overclocking.

Answer: (A)

Virtualization means creating virtual versions of hardware resources or entire machines so software can run in separate, isolated environments on the same physical hardware. This lets one physical server host multiple virtual machines, each with its own operating system and apps, managed by a software layer called a hypervisor. For example, you can run Windows in one virtual machine and Linux in another on the same physical server, dividing CPU time, memory, and storage among them as needed. This approach improves resource utilization, isolation, and simplicity in testing and deployment. The other options don’t fit virtualization: storing data exclusively in the cloud describes cloud storage, not virtualizing hardware or machines; physically dividing a server into multiple physical servers refers to hard partitioning of hardware, not creating virtual environments; and increasing CPU speed by overclocking is about performance tuning, not virtualization.
