Which of the following is a typical use case for queues?
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 where queues are used in real life. For example, when you stand in line at a store, the first person in line is the first to be served.
Step 3: Consider how operating systems manage tasks. They often have multiple processes (tasks) that need to be executed.
Step 4: Realize that operating systems use queues to manage these processes. When a process is ready to run, it is added to the queue.
Step 5: Understand that the operating system will execute the processes in the order they were added to the queue, just like people in a line.
