$2.$ Considering the process states illustrated in Fig. $1,$ if we assume that there are only four

$13$

transitions among the possible six, what are the two transitions that are not shown?

Furthermore, under what conditions or system design choices might these unrepresented transitions become feasible or necessary?

Process blocks for input

Scheduler picks another process

Scheduler picks this process

Input becomes available

Fig. $1$ A process can be in running, blocked, or ready state. Transitions between these states are as shown.
