An operating system is the most important software that runs on a computer $($Examples of OS: Windows, Linux, MAC, IOS, and Android$).$ Processes of an Operating System refer to running programs or programs that are executing. There are $2$ types of processes normal and primary process. In an operating system, multiple processes can run concurrently on a computer system. A process scheduler in an operating system is responsible for managing and controlling the execution of these multiple processes. The primary function of a process scheduler is to determines the order in which processes are executed on the CPU. It selects processes from the ready queue and allocates CPU time to each process based on a scheduling algorithms. For instance, the Round$-$Robin $($RR$)$ algorithm works as follows: Each processis given an equal time slot $($quantum $)$ to run in the CPU then it is interrupted in circular order$1.$ Therefore, the number of time slots for a processes i $=$ total execution time of processes i $/$ quantum length S
