What is FCFS?

In the world of computer science, algorithms play a crucial role in managing and organizing tasks and requests. One such algorithm is FCFS, which stands for First Come, First Served. The FCFS scheduling algorithm assigns tasks and requests a priority according to when they are expected to arrive. It adheres to the straightforward principle that the first job or request received is processed first. This implies that jobs are completed in the order that they are received, regardless of how complicated they are or how long they should take to complete.

Applications of FCFS:

Initial Offering Purchases of Crypto Assets: FCFS is frequently observed during the first issuance of cryptocurrency assets. In this case, it guarantees that the first people to apply for and be granted access to a certain cryptocurrency asset will be the ones to do so until the supply runs out. This method, which bases its decision entirely on the time of request, encourages equity and equal chance for all prospective purchasers.
Disk Scheduling: Computer systems use FCFS for disk scheduling, which controls the order in which files or data are accessed on storage devices. It keeps data requests equitable and streamlines the scheduling process.

Advantages of FCFS:

1. Simplicity: FCFS is simple to use and requires no intricate estimations or computations. The approach is simple to use and has a low computational cost.

2. Fairness: FCFS treats all tasks or requests equally based solely on their arrival time. This eliminates bias or favoritism and ensures fairness in task scheduling.

Limitations of FCFS:

1. Lack of Prioritization: FCFS does not prioritize tasks based on their importance or urgency. Critical or time-sensitive tasks may experience delays, leading to potential inefficiencies.

2. Waiting Times: FCFS can result in longer waiting times, especially for tasks that require significant processing time. This can lead to potential bottlenecks and delays for subsequent tasks.

3. Resource Utilization: FCFS does not consider task requirements or resource utilization. Tasks with high resource demands are not prioritized over those with lower requirements, leading to potentially inefficient resource allocation.
