Main purposes of CPU Scheduling Algorithm which is listed below
CPU scheduling is a process that allows one process to use the CPU while the execution of another process is on hold due to unavailability of any resource like I/O etc, thereby making full use of CPU. The aim of CPU scheduling is to maximize CPU utilization by making the system efficient, fast, and fair.
To make out the best use of the CPU and not to waste any CPU cycle, the CPU would be working most of the time(Ideally 100% of the time). Considering a real system, CPU usage should range from 40% (lightly loaded) to 90% (heavily loaded.)
There are many very different types of algorithms for different different tasks. By using them we can minimize waiting time, response time and turnaround time of processes. like turnaround time is minimized if most processes finish their next cpu burst within one time quantum.
