> Hey everyone, I wanted to ask why when doing a context switch from running to blocked on the sample solution when issuing the sleep command, it has the 10 usec transition from Running to Blocked outside the allocated 15usecs for sleeping and then the 10usec transition from Blocked to Running within the allocated 15usecs? Is this for all processes or just for sleep?

(from the perspective of the process) if a process wishes to sleep for 15usec, then it wishes to stop sleeping 15usec into the future. It doesn't care what happens when it is sleeping. So the actual time sleeping, can include (overlap) the transition time. Experiment: what happens if the process requests to sleep for *less* than the transition time?
