Virtualization in IT refers to the creation of virtual versions of hardware or software resources. This technology allows a single physical machine to run multiple virtual machines, effectively enabling one computer to perform the tasks of several, leading to better resource utilization, efficiency, and flexibility. For example, with virtualization, servers can host several operating systems, each with its applications running simultaneously on the same physical server. This not only reduces hardware costs but also simplifies management and increases efficiency in resource allocation and deployment.

The concept also applies to software resources, where applications can run in isolated environments (like virtual desktops) without affecting the underlying system. This flexibility supports various IT strategies, such as disaster recovery, cloud computing, and more efficient use of hardware resources.
