Question 1
What does the Earliest Deadline First algorithm prioritize?
- Tasks with longer execution time
- Tasks with earlier deadlines
- Tasks with lower priority
💡 Hint: Consider what it means to be 'earliest.'
Question 2
True or False: LLF can lead to thrashing in overloaded systems.
- True
- False
💡 Hint: Think about what happens when too many tasks need CPU time.

Challenge Problems
Push your limits with challenges.
Question 1
Suppose you have three tasks with the following characteristics: Task A with a period of 10ms and execution time of 3ms, Task B with a period of 20ms and execution time of 5ms, and Task C with a period of 15ms and execution time of 2ms. Analyze their schedulability under EDF.
💡 Hint: Remember the utilization calculation for EDF.
Question 2
Let’s assume that you have an overloaded system where tasks A, B, and C are causing 110% CPU utilization. Discuss how the behavior of EDF and LLF might differ in terms of task execution.
💡 Hint: Consider the difference between total deadlines being missed vs. operational efficiency.
