Operating Systems - Starvation vs Deadlock vs Livelock - Differences & Examples
In a system with multiple threads, which condition best exemplifies starvation?
In a system with multiple threads, which condition best exemplifies starvation?
easy💻 Programming Q1 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand starvation
Starvation occurs when a thread is perpetually denied access to resources due to scheduling policies favoring others.Step 2: Analyze options
A low-priority thread never gets CPU time because higher-priority threads keep running describes a low-priority thread never getting CPU time, which is classic starvation. Two threads hold resources and wait indefinitely for each other's resource describes deadlock, C describes livelock, and D is normal execution.Final Answer:
Option B -> Option BQuick Check:
Starvation means indefinite waiting due to priority [OK]
Quick Trick: Starvation = low priority thread waits forever [OK]
Common Mistakes:
MISTAKES- Confusing deadlock with starvation
- Thinking livelock is starvation
- Assuming starvation means thread termination
Trap Explanation:
PITFALL- Deadlock and livelock options seem similar but differ in resource holding and progress
Interviewer Note:
CONTEXT- Tests understanding of starvation concept and its distinction from deadlock and livelock
