Operating Systems - Starvation vs Deadlock vs Livelock - Differences & Examples
Identify the misconception in this statement: "Starvation and deadlock are the same because both cause processes to wait indefinitely."
Identify the misconception in this statement: "Starvation and deadlock are the same because both cause processes to wait indefinitely."
medium🐞 Bug Identification Q7 of Q15
Step-by-Step Solution
Solution:
Step 1: Analyze the misconception
The statement wrongly equates starvation and deadlock as identical.Step 2: Evaluate options
Starvation always leads to deadlock eventually. is false: starvation does not necessarily lead to deadlock.
Starvation involves indefinite waiting due to scheduling, deadlock involves circular resource waiting. correctly distinguishes starvation and deadlock.
Deadlock can be resolved by aging, starvation cannot. is false; aging prevents starvation, not deadlock.
Both starvation and deadlock require mutual exclusion to occur. is true; mutual exclusion is a condition for deadlock and can cause starvation.Final Answer:
Option B -> Option BQuick Check:
Starvation does not always cause deadlock [OK]
Quick Trick: Starvation ≠ deadlock; starvation doesn't always cause deadlock [OK]
Common Mistakes:
MISTAKES- Assuming starvation leads to deadlock
- Confusing aging effects
- Ignoring mutual exclusion role
Trap Explanation:
PITFALL- Candidates often conflate starvation and deadlock because both involve waiting, missing that starvation need not cause deadlock.
Interviewer Note:
CONTEXT- Reveals if candidate understands fundamental difference between starvation and deadlock.
