Which of the following is a real-world application of a queue?
Step 1: Understand what a queue is. A queue is a data structure that follows the First-In-First-Out (FIFO) principle, meaning the first item added is the first one to be removed.
Step 2: Think about real-life situations where people or items are lined up. For example, when you stand in line at a grocery store, the first person in line is the first to be served.
Step 3: Consider how computers manage tasks. When a computer has multiple tasks to perform, it needs to handle them in the order they arrive, just like a line of people.
Step 4: Recognize that operating systems use queues to manage processes. When a program starts, it is added to a queue, and the operating system processes them in the order they were received.
Step 5: Conclude that task scheduling in operating systems is a real-world application of a queue because it organizes tasks in a way that ensures fairness and efficiency.
