SJF/SRTF (Shortest Remaining Time First) | Preemptive | operating system | Bangla Tutorial

Описание: Welcome to CPU Scheduling Lecture 2 in the Operating System Bangla Tutorial Series 🎓

In this class, we explore the First Come First Serve (FCFS) scheduling algorithm — one of the simplest and most important non-preemptive CPU scheduling methods used in Operating Systems.

📚 Topics Covered in this Lecture:
What is FCFS Scheduling?
How Non-Preemptive Scheduling works in FCFS
Step-by-step Gantt Chart creation with examples in Bangla
Calculation of Waiting Time and Turnaround Time
Average Waiting Time & CPU Utilisation explained
Advantages and Disadvantages of FCFS Scheduling
Real-life analogy to understand the concept clearly

✨ Perfect for:
🎓 CSE / IT students studying Operating System
📊 Learners preparing for Lab Viva / Assignments / Exams
🧑‍💻 Beginners who want a clear and simple understanding of scheduling concepts

By the end of this lecture, you will be able to:
✅ Explain FCFS Scheduling in your own words
✅ Draw Gantt Charts and calculate average waiting time manually
✅ Understand why FCFS is non-preemptive and its limitations

👉 Watch till the end for step-by-step problem solving in Bangla.
