Operating Systems - Starvation vs Deadlock vs Livelock - Differences & Examples
Which situation best characterizes a deadlock in a resource-sharing environment?
Which situation best characterizes a deadlock in a resource-sharing environment?
easy💻 Programming Q2 of Q15
Step-by-Step Solution
Solution:
Step 1: Define deadlock
Deadlock occurs when processes hold resources and wait indefinitely for resources held by others, causing a cycle.Step 2: Evaluate options
Multiple processes hold resources and wait indefinitely for resources held by each other matches deadlock definition. A process is repeatedly denied CPU time due to low priority describes starvation, C describes livelock, and D is normal execution.Final Answer:
Option D -> Option DQuick Check:
Deadlock = circular wait with resource holding [OK]
Quick Trick: Deadlock = circular wait with held resources [OK]
Common Mistakes:
MISTAKES- Mixing starvation with deadlock
- Confusing livelock with deadlock
- Assuming deadlock means process termination
Trap Explanation:
PITFALL- Starvation and livelock options look like waiting but lack circular resource holding
Interviewer Note:
CONTEXT- Assesses ability to identify deadlock conditions in resource allocation
