Flashcards

What is Virtualization?

A technology that allows a single physical computer to run multiple independent virtual machines (VMs), each acting as a separate computer with its own operating system and resources.

Does virtualization software separate hardware from VMs?

Virtualization software creates a layer of abstraction between the physical hardware and the virtual machines, allowing each VM to operate independently.

Do VMs have their own OS?

Each virtual machine has its own operating system, allowing it to function as an independent computer.

Can a VM image be saved and restarted?

An image (a copy) of a VM can be saved as a file, allowing it to be easily backed up, moved, and restarted when needed.

Virtualization

A single computer can host multiple independent virtual computers, sharing the host computer's hardware.
Virtualization software does not physically separate the hardware from the virtual machine instances.
