Software called a _______ separates the machine's resources from the hardware and provisions them appropriately so they can be used by the VM.

• A. Hypervisor
• B. Emulator
• C. BIOS
• D. Hyperthreading

Answer: (A)

In virtualization, a layer sits between the physical hardware and the virtual machines to allocate resources and keep each VM separate. This role is fulfilled by a hypervisor, which abstracts CPU, memory, storage, and I/O and presents each VM with its own virtual hardware. It handles scheduling, memory management, and device access, enforcing isolation so one VM can’t directly reach another’s data. Emulators simply imitate different hardware in software, BIOS is firmware that initializes hardware at boot, and hyperthreading is a CPU feature for running multiple threads, not the management layer for VMs. Therefore, the term that best fits is hypervisor.
