Operating Systems - Process State Machine - Five-State Model
Identify the bug in the following statement about the five-state process model: "A process in the Terminated state can transition back to the Ready state if it is restarted."
Identify the bug in the following statement about the five-state process model: "A process in the Terminated state can transition back to the Ready state if it is restarted."
medium🐞 Bug Identification Q7 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand Terminated state semantics
Terminated means process execution is complete and resources are released.Step 2: No direct transition back to Ready
A terminated process cannot resume; a new process must be created.Step 3: Other options misunderstand Terminated state
Terminated is final, not temporary or automatic transition.Final Answer:
Option A -> Option AQuick Check:
Terminated processes require new creation, no direct Ready transition [OK]
Quick Trick: Terminated means process ended, no restart without new creation [OK]
Common Mistakes:
MISTAKES- Believing Terminated processes can resume
- Confusing Terminated with Waiting
- Assuming automatic cleanup leads to Ready
Trap Explanation:
PITFALL- Candidates often think Terminated is reversible without process recreation.
Interviewer Note:
CONTEXT- Tests understanding of process lifecycle finality.
