Different types of CPU scheduling

CPU scheduling is a crucial aspect of operating systems, and there are several types of CPU scheduling algorithms. Here are some of the most common ones:

1. First-Come-First-Served (FCFS):

In FCFS scheduling, the process that arrives first in the ready queue is executed first. This algorithm is simple and easy to implement, but it can lead to poor performance and starvation of other processes.

2. Shortest Job First (SJF):

In SJF scheduling, the process with the shortest burst time is executed first. This algorithm is optimal in terms of average waiting time, but it requires knowledge of the burst time of each process, which is not always possible.

3. Priority Scheduling:

In priority scheduling, each process is assigned a priority, and the process with the highest priority is executed first. This algorithm is useful in systems where certain processes require more urgent attention than others.

4. Round Robin (RR) Scheduling:

In RR scheduling, each process is given a fixed time slice (called a time quantum) to execute before the next process is scheduled. This algorithm is fair and provides good response time, but it can lead to overhead due to context switching.

5. Preemptive Scheduling:

In preemptive scheduling, the operating system can interrupt a running process and schedule another process. This algorithm is used in most modern operating systems and provides better responsiveness and fairness

6. Non-Preemptive Scheduling:

In non-preemptive scheduling, once a process is scheduled, it runs until it completes or blocks. This algorithm is simpler to implement but can lead to poor performance and starvation of other processes.
