    Scheduling algorithms in operating systems determine how processes are allocated CPU time. These algorithms aim to optimize CPU utilization, minimize waiting time, and ensure fairness. Below are the key types of scheduling algorithms:

    First-Come, First-Served (FCFS): This is the simplest scheduling algorithm where processes are executed in the order they arrive. It uses a FIFO (First In, First Out) queue. While easy to implement, it can suffer from the convoy effect, where long processes delay shorter ones.

    Shortest Job First (SJF): This algorithm selects the process with the shortest CPU burst time for execution. It minimizes average waiting time but can lead to starvation for longer processes. SJF can be non-preemptive or preemptive (Shortest Remaining Time First, SRTF).

    Round Robin (RR): Designed for time-sharing systems, RR assigns a fixed time slice (quantum) to each process. After the quantum expires, the process is preempted and added to the end of the queue. This ensures fairness but may involve frequent context switching.

    What is effective CPU scheduling?

    Effective CPU scheduling aims to minimize waiting times, maximize throughput, and ensure fair allocation of the CPU among competing processes. We have a simple explanation to understand the Main functions of the Operating System. The First-Come, First-Served (FCFS) algorithm is the simplest CPU scheduling algorithm.
