Q: A single physical computer, referred to as a host, may operate several distinct virtual instances, referred to as ______, thanks to virtualization.

Explanation: With the help of virtualization, a single physical system, which is referred to as a host, can operate a great number of separate virtual instances, which are referred to as “virtual machines” or VMs. Each virtual machine functions the same way as if it were a standalone physical computer, complete with its own set of apps and operating systems, although sharing the same underlying hardware. This makes it possible to employ resources more effectively and provides additional flexibility in the management and deployment of computer systems.
