VAX (an acronym for virtual address extension) is a series of computers featuring a 32-bit instruction set architecture (ISA) and virtual memory that was developed and sold by Digital Equipment Corporation (DEC) in the late 20th century.

What is the VAX/VMS Operating System (OS)? VAX/VMS, or Virtual Memory System, was an advanced operating system that DEC (Digital Equipment Corporation) developed for the DEC VAX (Virtual Address eXtension) processors.

What are VAX Computer Systems? VAX stands for Virtual Address eXtension. VAX computer systems refer to a series of 32-bit minicomputers designed by DEC or Digital Equipment Corporation. Simply put, VAX is the hardware, and DEC is the company that produced VAX. The series started with the VAX-11/780 in 1977 – the first commercially successful ...

5 天之前 · OpenVMS is a multi-user, multitasking operating system that supports virtual memory. OpenVMS supports clustering (up to 96 nodes) that provides distributed processing, resource sharing, and cluster uptimes of dozens of years.

With VAX, DEC extended its PDP-11 minicomputer architecture from 16 to 32 bits. The first model in the VAX “superminicomputer” line was the VAX-11/780. The line rivaled “much more expensive mainframe computers in performance,” according to the online Computer History Museum.

OpenVMS（全称Open Virtual Memory System，中文汉字意译为“开放虚拟内存系统”）是VAX计算机的早期操作系统，是美国DEC公司（Digital Equipment Corporation，DEC）为其VAX以及Alpha计算机开发的操作系统。

What is OpenVMS? OpenVMS (VMS) is a server OS sold by VMS Software, Inc. (VSI). This operating system runs on VAX, Alpha, Integrity, and soon x86 systems.

Diverse workloads and a wide range of hardware configurations compound the complexity of an operating system's memory management policies. Virtual Memory Management

The VAX VMS operating system, known as VAX/VMS, is an advanced system that was developed for the VAX line of minicomputers. VMS stands for Virtual Memory System, a feature that effectively increases the computer’s memory capacity by allowing it to use disk or other peripheral storage as additional memory.

The Virtual Memory System (VMS) is an OS originally designed for the DEC VAX line of servers. Over time, the OS grew to support Alpha and Itanium based machines. Released initially in 1977, the OS was a major competitor at the time to UNIX based machines.
