## FAQs on Rate Monotonic Algorithm (RMS) & Earliest Deadline First (EDF) Video Lecture - Embedded Systems (Web) - Computer Science Engineering (CSE)

 1. What is the Rate Monotonic Algorithm (RMS)?
Ans. The Rate Monotonic Algorithm (RMS) is a scheduling algorithm used in real-time operating systems. It assigns fixed priorities to tasks based on their periods, where tasks with shorter periods have higher priorities. The RMS algorithm ensures that tasks with higher priority are always scheduled before tasks with lower priority.
 2. What is Earliest Deadline First (EDF)?
Ans. Earliest Deadline First (EDF) is a scheduling algorithm used in real-time operating systems. Unlike the Rate Monotonic Algorithm (RMS), EDF assigns priorities to tasks based on their deadlines. The task with the earliest deadline is given the highest priority. EDF dynamically adjusts priorities as deadlines approach to ensure tasks are completed on time.
 3. What are the advantages of the Rate Monotonic Algorithm (RMS)?
Ans. The advantages of the Rate Monotonic Algorithm (RMS) include: 1. Simplicity: The RMS algorithm is relatively simple to understand and implement. 2. Determinism: The fixed priorities assigned by RMS guarantee deterministic task scheduling. 3. Schedulability: If a set of tasks is schedulable using RMS, it is guaranteed to meet all deadlines. 4. Efficiency: RMS minimizes overhead by avoiding dynamic priority adjustments.
 5. How do the Rate Monotonic Algorithm (RMS) and Earliest Deadline First (EDF) differ?
Ans. The Rate Monotonic Algorithm (RMS) and Earliest Deadline First (EDF) differ in terms of priority assignment and deadline considerations. RMS assigns fixed priorities based on task periods, while EDF assigns priorities based on deadlines. RMS assumes periodic tasks, while EDF can handle both periodic and aperiodic tasks. Moreover, RMS does not adjust priorities dynamically, while EDF dynamically adjusts priorities as deadlines approach.
