List of Operating Systems
Did you know Windows 3.2 was a Chinese only release? Or how about the fact that General Electric made their own Operating System?
Those are just a few of the interesting nuggets of information you will find in the Wikipedia’s List of operating systems.
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.
Some of the most funny things come in under Fictional Operating Systems where they mention LCARS from Star Trek, and Jesux, a linux distro supposedly for Christian hackers but was found to be a hoax.
