Which technology allows for multiple operating systems to be run on a single host computer?

The technology that allows for multiple operating systems to be run on a single host computer is called virtualization. Virtualization enables the creation of virtual machines (VMs), which are isolated environments that can run their own operating systems and applications independently of the underlying physical hardware. Virtualization is a fundamental technology that has transformed the way IT resources are managed and utilized, providing greater flexibility, efficiency, and scalability in computing environments.
