What is CPU scheduling and why is it important?

CPU scheduling is the method by which an operating system decides which process runs at a given time. It's crucial for optimizing CPU usage and ensuring that all processes get fair access to the CPU.

What are the different types of CPU scheduling algorithms?

There are several types of CPU scheduling algorithms, including First-Come, First-Served (FCFS), Shortest Job Next (SJN), Round Robin (RR), and Priority Scheduling. Each has its own advantages and disadvantages.

Can you explain how Round Robin scheduling works?

Round Robin scheduling assigns a fixed time slice to each process in the queue. When a process's time slice expires, it is moved to the back of the queue, allowing the next process to run.

What are the advantages of using Priority Scheduling?

Priority Scheduling allows more important processes to run first, which can lead to better performance for critical tasks. However, it can also lead to starvation for lower-priority processes.
