Given a system with states Idle, Active, and Paused, and transitions:
Idle -start-> Active
Active -pause-> Paused
Paused -resume-> Active
What is the state after the sequence of events: start, pause, resume?
AActive
BError state
CPaused
DIdle
Step-by-Step Solution
Solution:
  1. Step 1: Follow the event sequence from initial state

    Start at Idle. Event 'start' moves Idle to Active. Then 'pause' moves Active to Paused. Finally, 'resume' moves Paused back to Active.
  2. Step 2: Determine final state

    After all events, the system is in Active state.
  3. Final Answer:

    Active -> Option A
  4. Quick Check:

    Event sequence leads to Active state [OK]
Quick Trick: Trace events step-by-step to find final state [OK]
Common Mistakes:
  • Skipping an event in the sequence
  • Confusing pause and resume transitions
  • Assuming system resets to Idle
