Abstract: One of the most important jobs of an operating system is to schedule processes. The most important thing is to make sure that a lot of processes in the RAM's ready queue are using the CPU at once. You should also monitor CPU usage, response time, wait time, and turnaround time. This paper looks at how changing contexts affect the scheduling process in the Multi-Level Feedback Queue (MLFQ) system. The goal is to determine how often context switches occur. With that information, we can then figure out response time, CPU usage, and data transfer. The study also looks at how to fix negative effects, such as making things more flexible and reducing unnecessary context switching. The main goal of this paper is to help people who design and implement operating systems use resources more efficiently when many tasks are running at once. They will find the results very helpful. The main goal of this paper is to improve the system and make it easier for people to use.

Keywords: operating system, scheduling algorithms quantum, multilevel feedback queue, context switching, optimization, and CPU utilization
