The creation of virtual versions of physical devices or resources is called what?

• A. Mirroring
• B. Casting
• C. Virtualization
• D. Hypervisor

Answer: (C)

Creating virtual versions of physical devices or resources is virtualization. It means abstracting actual hardware so software can use virtual, not physical, components—like running multiple virtual machines on one physical server, or presenting virtual disks, networks, and NICs to software. A hypervisor is the software layer that makes this possible by partitioning and managing those virtual resources. Mirroring duplicates data or displays a copy of something, not a virtualized resource; casting is streaming content to another device. Hypervisor is a key enabling technology, but the overall process and result described here are virtualization.
