The not running state in the two state model is not a good representation for process that are not currently being executed.
If a process is not currently running, then two cases are possible
1. Process is waiting for some I\O and is blocked.
2. Process is waiting to be executed and is in the ready state
The above conditions are very different and cannot be depicted by a single state.
That is why the split was done

State transition diagram used for operating system management of the Process Control Block has the following states A New (Create)– In this step, process is about to be created but not yet created, it is the program which is present in secondary memory that will be picked up by OS to create the process. Ready -> Ready to run. After creation of a process, the process enters the ready state i.e. the process is loaded into the main memory. The...

Operating Systems: 1. Given the three thread states: running, runnable (i.e., ready), and blocked (i.e., waiting), state which of the six possible thread transitions are allowed, and which ones are not. Also, for each case, provide an example of how the transition occurs, or a reason why it cannot (as a justification for each of your answers). Assume Mesa-style scheduling.
