* The first versions of the [[C (programming language)|C]] language and the [[Unix]] operating system ran on DEC's [[Programmed Data Processor|PDP]] series of computers (first on a PDP-7, then the [[PDP-11]]), which were among the first commercially viable [[minicomputer]]s, although for several years DEC itself did not encourage the use of Unix.
* DEC produced widely used and influential interactive operating systems, including [[OS/8|OS-8]], [[TOPS-10]], [[TOPS-20]], [[RSTS/E]], [[RSX-11]], [[RT-11]], and [[OpenVMS]]. PDP computers, in particular the PDP-11 model, inspired a generation of programmers and software developers. Some PDP-11 systems more than 25 years old (software and hardware) are still being used to control and monitor factories, transportation systems and nuclear plants. DEC was an early champion of [[time-sharing]] systems.
* The [[command-line interface]]s found in DEC's systems, eventually codified as [[DIGITAL Command Language|DCL]], would look familiar to any user of modern microcomputer CLIs; those used in earlier systems, such as [[Compatible Time-Sharing System|CTSS]], [[IBM]]'s [[Job Control Language|JCL]], or [[Univac]]'s time-sharing systems, would look utterly alien. Many features of the [[CP/M]] and MS-DOS CLI show a recognizable family resemblance to DEC's OSes, including command names such as DIR and HELP and the "name-dot-extension" file naming conventions.
* [[Notes-11]] and its follow-on product, {{vanchor|VAX Notes}}, were two of the first examples of online collaboration software, a category that has become to be known as [[Collaborative software|groupware]]. [[Len Kawell]], one of the original Notes-11 developers, later joined [[Lotus Development Corporation]] and contributed to their [[Lotus Notes]] product.
* The [[MUMPS]] programming language, with its built-in database, was developed on the PDP-7, 9, and 15 series machines. MUMPS is still widely used in [[Health informatics|medical information systems]], such as those provide by [[Meditech]] and [[Epic Systems]].
* The [[Babel Fish (website)|Babel Fish]] machine translation service was developed by DEC researchers, and was one of the first machine translators to achieve broad success using natural language processing techniques.
* [[ALL-IN-1]] was an office automation system developed by Skip Walter and others in Central Engineering under Gordon Bell. They developed a customizable list of application invocations and the robust DECMail product that provided one of the first commercially available electronic mail systems.<ref>{{cite web |date=January 30, 1998 |title=1982 Timeline |url=https://research.microsoft.com/en-us/um/people/gbell/Digital/timeline/1982.htm |access-date=January 9, 2014 |work=DIGITAL Computing Timeline}}</ref><ref>{{cite web |date=January 30, 1998 |title=ALL-IN-1 |url=https://research.microsoft.com/en-us/um/people/gbell/Digital/timeline/1982-4.htm |work=DIGITAL Computing Timeline}}</ref>
