An Acronym for Virtual Memory System.

VMS is an OperatingSystem written by DEC for their VAX line of minicomputers. In 1990, around version 5.5, DEC renamed it to OpenVMS, after VMS was certified as having high support for POSIX standards. Shortly thereafter, OpenVMS was ported to the Alpha architecture, released as OpenVMS for AXP 1.0 in 1992. Following the history of DEC, OpenVMS is now owned by HP.

OpenVMS currently runs on VAX and Alpha, respectively known as OpenVMS for VAX and OpenVMS for Alpha. Support for the Itanium has been announced.
