List of operating systems
From Wikipedia, the free encyclopedia
Operating systems can be categorized by technology (Unix-like or others such as Windows), ownership and license (proprietary or open source), working state (historic like MS-DOS and OS/2 or current like Linux and Windows), application (general like Linux, Windows), desktop only (MS-DOS, MacOS), mainframe only (VM), real-time or embedded only (QNX), PDA, or purpose (production, research, hobby). Naturally, these groupings overlap.
[edit] Early, and historically important
- CTSS (The Compatible Timeshare System, developed at MIT by Corbato, et al)
- Incompatible Timesharing System (ITS, developed at MIT for the DEC 10 / 20 mainframes)
- THE multiprogramming system (by Dijkstra et al.)
- Multics (joint OS development project by Bell Labs, GE, and MIT)
- Master programme (developed for Leo Computers, Leo III in 1962)
