True or False: Do VMs have a BIOS, hard disk, memory, CPU, and Operating System?

• A. True
• B. False
• C. Not Sure
• D. Depends

Answer: (A)

A virtual machine provides a complete, bootable computer platform to the guest operating system by emulating hardware for it. It includes a virtual BIOS or firmware to initialize the virtual hardware and start the boot process, a virtual CPU to execute instructions, memory allocated by the hypervisor, a virtual hard disk that acts as storage, and an operating system that runs inside the VM on that virtual disk. The hypervisor maps these virtual components to the host’s physical resources, so the guest OS experiences a real, working computer. So the statement is true because VMs are designed to present all these elements as a cohesive, functioning system to the guest OS.
