discussion

The control of processes and threads are of deep concern by developers of all operating systems capable of handling "real or emulated" simultaneous computer activity. Threads are typically created by processes (initially invoked by the user or another process). Discuss how an operating system manages these processes and threads, how they are instantiated and discarded, how the activity is controlled, along with the respective advantages and disadvantages of both process and thread. Do not discuss MS Windows OS. Instead you may choose from Linux, UNIX, ROS, z/OS, or VM.
