## Answers

### Answer by Hitesh Vohra

- [**Operating**](https://answers.mindstick.com/qa/50234/in-what-way-you-can-increase-the-game-performance-in-your-windows-operating-system) systems and networks employ the **First Come, First Served (FCFS)** scheduling method to efficiently and automatically execute queued tasks, processes, and requests in the order of their arrival. A first-in, first-out (FIFO) or first-come, first-choice (FCFC) scheduling technique is sometimes known as an FCFS scheduling algorithm.
- An **FCFS a**lgorithm is predictable due to its simplicity, independent of the tasks or requests it must complete. FCFS algorithms mirror real-life customer service situations, such as grocery store checkout lines, where consumers who arrive first are served first, regardless of the magnitude or complexity of their transaction.
