A hypervisor, also known as a virtual machine monitor (VMM), is software that creates and runs virtual machines (VMs). It allows multiple VMs to share a single hardware host, with each VM having its own operating system. Hypervisors are categorized into two types: Type 1 (bare-metal), which run directly on the host's hardware, and Type 2 (hosted), which run on a conventional operating system. Hypervisors are essential in virtualization, enabling efficient resource utilization and isolation in web hosting and cloud computing.
