Which statement describes a Virtual Machine?

• A. Is a type of hardware peripheral
• B. Enables a computer or device to run another operating system in addition to the one installed
• C. Is used to manage files
• D. Is a network protocol

Answer: (B)

A virtual machine is a software-defined computer that runs inside another computer. It uses virtualization software to create a separate, isolated environment with its own virtual CPU, memory, storage, and network interface. This setup lets you install and run another operating system inside your current system, effectively having multiple operating systems on one physical machine. That’s why the statement describing running another OS in addition to the one installed is the best fit.

It’s not a hardware peripheral, so it isn’t a physical device you connect. It’s not primarily about managing files, so it doesn’t describe file management tasks. And it isn’t a network protocol, which is a set of rules for data exchange.
