Multics (Multiplexed Information and Computing Service) is another experimental operating system developed by the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric long back in 1960. But they did not succeed in converting it as a commercial version. Yet its improved security measures were appreciable.
