  • Question
  • What is the difference between Hard and Soft real-time systems?


  • Correct Answer
  • A hard real-time system guarantees that critical tasks complete on time This goal requires that all delays in the system be bounded from the retrieval of the stored data to the time that it takes the operating system to finish any request made of it A soft real time system where a critical real-time task gets priority over other tasks and retains that priority until it completes As in hard real time systems kernel delays need to be bounded
