A computer operating system originally developed by Digital Equipment Corporation for their VAX computers, later ported to other architectures.
Originally called VMS (Virtual Memory System) when introduced in 1977, it was renamed OpenVMS in the 1990s when Digital began opening the system to third-party development. The 'Open' prefix reflected the industry trend toward open systems and standards.
OpenVMS is renowned for its exceptional reliability and security, with some systems running continuously for decades without failure. The operating system introduced many concepts that later became standard, including sophisticated cluster computing and advanced memory management techniques that influenced modern operating system design.
