Virtual refers to something that exists or operates in a simulated or emulated environment, rather than in physical reality. In computing, virtualization refers to the creation of a virtual version of a physical resource, such as a server, operating system, storage device, or network, using software or hardware. Virtualization allows multiple virtual resources to operate on a single physical resource, providing greater flexibility, scalability, and cost-effectiveness. For example, virtualization can be used to create virtual machines (VMs) that can run multiple operating systems on a single physical server, or to create virtual storage pools that can be accessed by multiple users or applications. Virtualization is widely used in data centers, cloud computing, and virtual desktop infrastructure (VDI) to optimize resource utilization, reduce costs, and improve system performance and availability. Virtualization is a key technology that enables the efficient use of computing resources in today’s complex and dynamic IT environments.
