Re: OpenVMS

Close.

VAX is specific 32 bit hardware developed by Digital Equipement Computers.

VMS was the name of the most important, but not only, OS running on it.

OpenVMS is a marketing driven rename of VMS.

Re: OpenVMS

Shiva,

You might have gone thru the docs Mr.Hein mentioned.

VAX is a hardware (32 bit) and
VMS is a Operating System by Digital Equipment Corp. (DEC).

VMS then became OpenVMS (X/Open consortium certified OpenVMS is the first OS with OPEN System compliance).

DEC then developed the world first 64 Bit computer called ALPHA.

The OpenVMS runs on both of their hardwares - VAX (32 bit) and ALPHA (64).

Now this OpenVMS runs on Intel's I64 server also, because I64 server architecture initially designed by DEC.

The VMS system's project manager, Dave Cutler was the project manager for Microsoft's WinNT also.

You can find more ineteresting info about the DEC's history and Dave here...
