Operating Systems - Process vs Thread - Key Differences
You need to design a system that isolates failures so that a crash in one execution unit does not affect others. Which approach best fits this requirement?

easy🔍 Pattern Recognition Q1 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand process isolation
Processes have separate memory spaces and resource ownership, so a crash in one process does not affect others.Step 2: Analyze thread behavior
Threads share the same memory space within a process, so a fault in one thread can corrupt shared memory and crash the entire process.Step 3: Evaluate other options
Single process with async callbacks or event-driven programming does not provide memory isolation; failures can propagate.Final Answer:
Option A -> Option AQuick Check:
Process isolation ensures failure containment [OK]
Quick Trick: Process isolation means separate memory spaces [OK]
Common Mistakes:
MISTAKES- Assuming threads isolate failures due to concurrency
- Confusing asynchronous programming with isolation
Trap Explanation:
PITFALL- Candidates often think threads isolate failures because they run independently, ignoring shared memory risks.
Interviewer Note:
CONTEXT- Tests understanding of process vs thread isolation and failure containment.
