I have been teaching Operating Systems basics in a class and after Processes, Child Processes and Threads, we have managed to move to "Process Scheduling"
Now, ironically, as we know that it is not the Process which is scheduled, but the threads precisely (we are following Linux Ubuntu there).
Here is what Silberchatz book (by the way, the title of the chapter is also "Process Scheduling") says about it:
In Chapter 4, we introduced threads to the process model. On operating systems that support them., it is kernel-level threads-not processes-that are in fact being scheduled by the operating system. However, the terms process scheduling and thread scheduling are often used interchangeably.
(Silberschatz, Operating System Concepts, 8th Edition)
Although, I have taught them the respective algorithms; should I bring this discussion within the class and press the panic button by telling that its not the Processes which are scheduled but Threads? This question has been in my mind since long time and I couldn't look for a better place to get an answer than here.
