List of operating systems

From Academic Kids

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 DOS and OS/2 or current like Linux and Windows), application (general like Linux, Windows), desktop only (DOS, Apple), mainframe only (AIX), real-time or embedded only (QNX), PDA, or purpose (production, research, hobby). Naturally, these groupings overlap.
