		PC Updates to a New Value
		Process Calls a static Declared Function
		Process Writes to Main Memory

		All of the Above
		None of the Above

Expert Solution

Step 1

There are following 6 transition that occurs among Running, Ready, Blocked, and Terminated state of a process:

Transition 1 happens when the process can not continue its execution. The process that is running initiates an input/output operation before its assigned time expires, and relinquishes the CPU control.

Running -> Block
Transition 2 occurs when the running process has executed for a longer duration then scheduler picks another process from ready queue.

Running -> Ready
Transition 3 occurs when all processes have executed with their shared time slice and the scheduler picks the first process to run again from the ready queue.

Ready -> Running
Transition 4 happnes when some external event such as input arrival for which a process is being waiting occurs.

Blocked -> Ready
Transition 5 happens while creating the process.

New -> Ready
Transition 6 exist when the process has finished its complete execution.

Running -> Terminated
