Operating Systems - Starvation vs Deadlock vs Livelock - Differences & Examples
Consider a system where two processes repeatedly yield to each other to avoid deadlock but never proceed. What is this scenario an example of?
Consider a system where two processes repeatedly yield to each other to avoid deadlock but never proceed. What is this scenario an example of?
easy🧠🧾 Concept Trace Q3 of Q15
Step-by-Step Solution
Solution:
Step 1: Analyze the scenario
Processes repeatedly yielding to each other without progress is livelock.Step 2: Eliminate other options
Starvation is indefinite waiting due to priority.
Deadlock is circular waiting with no state changes.
Priority inversion is a priority scheduling issue.Final Answer:
Option A -> Option AQuick Check:
Livelock = active state changes but no progress [OK]
Quick Trick: Livelock = active but no progress [OK]
Common Mistakes:
MISTAKES- Confusing livelock with deadlock
- Thinking yielding avoids livelock
- Mixing starvation with livelock
Trap Explanation:
PITFALL- Candidates often mistake livelock for deadlock because both involve no progress, but livelock involves active state changes.
Interviewer Note:
CONTEXT- Tests understanding of livelock vs deadlock and starvation.
