Virtualization refers to the process of creating a virtual version of a device or resource, such as a server, storage device, network, or operating system. This concept allows the abstraction of physical hardware into multiple virtual instances that can operate independently. The primary benefit of virtualization is that it enables more efficient utilization of hardware resources, as multiple virtual machines (VMs) can run on a single physical host, sharing its resources while appearing as separate entities to users and applications.

For example, in a data center, virtualization can mean running several virtual servers on a single physical server, allowing for better resource management, flexibility, and scalability. This approach leads to improved efficiency, reduced costs, and simplified management of IT resources. Therefore, the correct answer highlights the essence of virtualization, which is about creating a virtual representation rather than the physical duplication or enhancement of hardware alone.
