Part of the Operating systems glossary: VMS (Virtual Memory System) is an operating system from the Digital Equipment Corporation (DEC) that runs in its older mid-range computers. VMS originated in 1979 as a new operating system for DEC's new VAX computer, the successor to DEC's PDP-11. VMS is a 32-bit system that exploits the concept of virtual memory. VMS was renamed OpenVMS when it was redeveloped for the Alpha processor.
A hypervisor or virtual machine monitor (VMM) is a piece of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems.
