Consider the state transition diagram of figure 39b , Ask an Expert

Engineering

Consider the state transition diagram of Figure 3.9b . Suppose that it is time for the
OS to dispatch a process and that there are processes in both the Ready state and the
Ready/Suspend state, and that at least one process in the Ready/Suspend state has
higher scheduling priority than any of the processes in the Ready state. Two extreme
policies are as follows: (1) Always dispatch from a process in the Ready state, to minimize
swapping, and (2) always give preference to the highest-priority process, even
though that may mean swapping when swapping is not necessary. Suggest an intermediate
policy that tries to balance the concerns of priority and performance
