WebJul 7, 2024 · The lowest level processes suffer from starvation problem. 2. First Come First Served (FCFS) Scheduling Algorithm: It is the simplest and non-preemptive scheduling algorithm. In First Come First Served (FCFS), the process is allocated to the CPU in the order of their arrival. A queue data structure is used to implement the FCFS scheduling ... WebAug 8, 2024 · In First Come First Served (FCFS) algorithm, the process that arrives first, is sent first for execution by the CPU when CPU is free. The main disadvantage of this algorithm is that the average waiting time is often quite long. It also leads to the convoy effect. This results in lower device or CPU utilization and lower efficiency. 2.

WebFirst-come-first-served (FCFS) scheduling can lead to starvation if a process with a long execution time arrives first and other processes with shorter execution times are continually added to the queue. These shorter processes will have to wait a long time before they are executed, which can cause them to starve.
