Computer technology: what is a hypervisor?

For me, understanding computer technology requires constant self-tutoring. The tutor defines the term hypervisor.

In my Feb 15 post I explain the idea of a virtual machine. The virtual machine exists atop a hypervisor.

hypervisor (noun):

a program that allows one or more virtual machines (VMs) to function from a single hardware entity. It may host a distinct instance of the same operating system to each VM, or perhaps even different operating systems to different VMs.

The hypervisor exists as a layer above the hardware but below the VMs. The users of the VMs needn’t be aware of the hypervisor.
