What is Hypervisor?

A hypervisor, also known as a virtual machine monitor (VMM), is software or hardware that creates and runs virtual machines (VMs). It allows multiple operating systems (guests) to run concurrently on a single physical host machine, sharing hardware resources like CPU, memory, and storage. Hypervisors are commonly used for server virtualization, desktop virtualization, and cloud computing to improve resource utilization, reduce costs, and enhance manageability.
