What is meant by virtualization in the context of computing?

In the context of computing, virtualization refers to the creation of a simulated or virtual version of something, such as operating systems, servers, storage devices, or network resources. This typically involves running multiple operating systems on a single physical machine, allowing different environments to function independently.

The answer related to a new "physical" machine created by software aligns with the concept of virtualization because it highlights the ability to create virtual machines (VMs) that function as if they are separate physical devices. When virtualization is implemented, these virtual machines can operate on the resources of a single physical machine while maintaining their own operating systems and applications.

This ability to mimic physical machines offers significant benefits such as better resource allocation, cost efficiency, and improved flexibility for deployment and management of IT resources. It allows businesses to utilize their hardware more effectively and supports various configurations without the need for additional physical devices.

Other options, while relevant to varying aspects of network and system management, do not accurately describe the core idea of virtualization. For example, a software-only environment to simulate hardware captures some of the essence of virtualization but does not fully encompass the idea of creating separate, functioning instances that can operate independently like a physical machine. Creating an isolated network pertains more to network security rather than virtualization
