Which of the following best describes the primary trigger for a process transition from the Ready state to the Running state in the five-state process model?
easy🔍 Pattern Recognition Q1 of Q15
Step-by-Step Solution
Solution:
Step 1: Identify the event causing Ready to Running transition
The transition from Ready to Running occurs when the CPU scheduler selects the process to execute.Final Answer:
Option C -> Option CQuick Check:
Scheduler dispatches process -> Running state [OK]
Quick Trick: Ready to Running requires scheduler dispatch [OK]
Common Mistakes:
MISTAKES- Confusing I/O completion with Ready to Running
- Assuming termination triggers Running state
- Believing I/O request triggers Running
Trap Explanation:
PITFALL- Candidates often confuse I/O completion (Waiting to Ready) with CPU scheduling (Ready to Running).
Interviewer Note:
CONTEXT- Tests understanding of scheduler's role in state transitions.
