**What technology allows for the creation of virtual machines?**
Virtualization technology enables the creation of virtual machines (VMs). This technology abstracts physical hardware resources, allowing multiple operating systems to run concurrently on a single physical machine. Hypervisors, such as VMware and Hyper-V, manage these virtual environments, allocating resources dynamically and isolating VMs from each other for security. This capability increases hardware utilization, simplifies management, and facilitates easy backup and recovery, making virtualization essential in modern cloud computing and enterprise environments.
