In priority scheduling, if two processes have the same priority, some operating systems may use a secondary criteria, such as time since last execution or process ID, to determine the order in which they are executed. Alternatively, the operating system may use a first-come-first-serve basis for scheduling processes with the same priority.

By far the simplest CPU-scheduling algorithm is the first-come, first-served (FCFS) scheduling algorithm. With this scheme, the process that requests the CPU first is allocated the CPU first. The implementation of the FCFS policy is easily managed with a FIFO queue. When a process enters the ready queue, its PCB is linked onto the tail of the queue. When the CPU is free, it is allocated to the process at the head of the queue. The running process is then removed from the queue. The code for FCFS scheduling is simple to write and understand. The average waiting time under the FCFS policy, however, is often quite long. Consider the following set of processes that arrive at time 0, with the length of the CPU-burst time given in milliseconds:
In scheduling algorithms, the priority method assigns tasks based on their importance, while the First-Come, First-Serve (FCFS) algorithm processes tasks in the order they arrive, regardless of priority. This means that in FCFS, a lower-priority task can delay a higher-priority one if it arrives first. Consequently, the two algorithms can lead to different performance outcomes, particularly in terms of response time and overall system efficiency. In contrast, priority scheduling aims to minimize wait times for high-priority tasks, potentially at the cost of lower-priority ones.
New requests for the track over which the head currently resides can theoretically arrive as quickly as these requests are being serviced

First-come, first-served (FCFS) - sometimes first-in, first-served and first-come, first choice - is a service policy whereby the requests of customers or clients are attended to in the order that they arrived, without other biases or preferences. The policy can be employed when processing sales orders, in determining restaurant seating, on a taxi stand, etc. In Western society, it is the standard policy for the processing of most queues in which people wait for a service or two.
