CPU scheduling determines which process gets CPU time while others wait. The goal is to maximize CPU utilization by ensuring that whenever the CPU is idle, a process from the ready queue is selected for execution. The CPU scheduler manages this selection, choosing from processes in memory that are ready to run. Different scheduling algorithms, like FCFS, SJF, Round Robin, and Priority Scheduling, help optimize performance based on factors like response time and throughput. Efficient CPU scheduling ensures better resource utilization, reduces waiting time, and improves system responsiveness, making it a critical part of modern operating systems.
CPU scheduling is broadly classified into two main types, each with its own subcategories. Below, we provide a comprehensive discussion of these scheduling algorithms.
There are mainly five types of process scheduling algorithm
