Consider the following figure of a process image PCB Process ID State Program Counter Memory pointers Contextdata Others E SP PSW Program Code Static/Global Heap Stack Memory Note that during a process switch, the dispatcher does not include the memory pointers when saving the execution context. a. Explain why this is the correct behavior if the OS is operating under the 5-state process model (Figure 3.6 of textbook). b. Suppose the OS is operating under the 7-state process model (Figure 3.9(b) of textbook), describe how the OS should interact with the memory pointers when there are Suspend states in the model.
