i would say that is right - an OS should be managing multiple processes. cp/m certainly did not do that - but i know nothing about RTOSs.

- pjmlp 2y agoMany of the early 1950 - 1970 OSes did not had the notion of multiple processes, only jobs processed in batch. Many RTOS don't have processes, only tasks, which depending on the nature of the OSes can be cooperatively or preemptively scheduled. Also everything is linked together and deployed as a single execution unit into the hardware firmware. So again, by the same definition, when using cooperative scheduling, they aren't OSes.
