Process Scheduling is a fundamental function of the operating system that determines the order in which processes access the CPU and other system resources.
- It manages the execution of processes, deciding which process will run, when, and for how long.
- Effective scheduling improves system performance, resource utilization, and user responsiveness.
Key Objectives of Process Scheduling
The main objectives of process scheduling are to:
- Maximize CPU Utilization: Keep the CPU as busy as possible by minimizing idle time.
- Maximize Throughput: Increase the number of processes completed in a given time frame.
- Minimize Turnaround Time: Reduce the total time taken to execute a process from submission to completion.
- Minimize Waiting Time: Decrease the time processes spend waiting in the ready queue.
- Minimize Response Time: Improve responsiveness for interactive processes by reducing the time from a request to the first response.
