Exam 2: Operating System and Process Management: Part A

Suppose that a process is in "Blocked" state waiting for some I/O service. When the service is completed, it goes to the :

In a multi-programming environment :

When the process issues an I/O request :

The only state transition that is initiated by the user process itself is :
