In FreeRTOS, which characteristic most accurately describes a hard real-time system?
ATasks can miss deadlines occasionally without affecting system performance
BTasks must complete their execution within a strict deadline or system failure occurs
CTask scheduling is based solely on round-robin time slicing
DTasks run only when the CPU is idle
Step-by-Step Solution
Solution:
Step 1: Understand hard real-time definition
Hard real-time systems require tasks to meet strict deadlines to avoid failure.
Step 2: Analyze options
Tasks must complete their execution within a strict deadline or system failure occurs correctly states the strict deadline requirement. Options B, C, and D describe soft real-time or unrelated scheduling behaviors.
Final Answer:
Tasks must complete their execution within a strict deadline or system failure occurs -> Option B
Quick Check:
Hard real-time means strict deadlines must be met [OK]
Quick Trick:Hard real-time = strict deadlines, no misses allowed [OK]
Common Mistakes:
Confusing soft real-time with hard real-time
Assuming round-robin scheduling defines hard real-time
Believing tasks run only when CPU is idle
