WebLab 2: SCHEDULING ALGORITHMS Programming Instructions: 1. Write a program that will perform the following scheduling algorithms: a) FCFS b) SJF c) Priority d) Round Robin. 2. The user will decide what the program should do (Figure 1.1). The program should run indefinitely until the user decides to terminate it. WebFirst Come First Served (FCFS) is a Non-Preemptive scheduling algorithm. FIFO (First In First Out) strategy assigns priority to process in the order in which they request the processor. The process that requests the CPU first is allocated the CPU first. This is easily implemented with a FIFO queue for managing the tasks.

Priority Scheduling is a method of scheduling processes that is based on priority. In this algorithm, the scheduler selects the tasks to work as per the priority. The processes with higher priority should be carried out first, whereas jobs with equal priorities are carried out on a round-robin or FCFS basis.
