Is a Technology to Run Multiple Same or Different Operating Systems Which Is Completely Isolated from Each Other?

Virtualization allows you to take a single physical device (e.g., one workstation or server) and run multiple instances of operating systems. Each of these instances looks and operates as its own device, but because they coexist on a single physical device, they are considered to be virtual machines.

Which technology concept allows you run multiple operating systems on the same hardware?

Virtualization software — programs that allow you to run multiple operating systems simultaneously on a single computer — allows you to do just that. Using virtualization software, you can run multiple operating systems on one physical machine.

Is it possible to run completely different operating systems on virtual machines?

Yes, Virtualization makes it possible— to have VMs, running different operating systems, on a single host. Yes, Containerization makes it possible—to have VMs that are unique physical entities, so you can have completely different Operating Systems on them.
