What are some real-world examples of stacks and queues?

Stacks and queues are fundamental data structures used in various applications. For example, a stack can be seen in the 'undo' feature of text editors, where the last action taken is the first to be undone. A queue is used in print spooling, where print jobs are processed in the order they are received.

Can you explain how a stack works in a web browser?

Certainly! In a web browser, the stack is used to manage the history of pages visited. When you navigate to a new page, it gets pushed onto the stack. If you hit the back button, the browser pops the current page off the stack and returns to the previous one.

What about queues? How are they used in customer service?

In customer service, queues are used to manage incoming calls or requests. When a customer calls, they are placed in a queue, and the first person to call is the first to be served, ensuring a fair and orderly process.

Are there any other examples of queues in technology?

Yes, queues are also used in task scheduling for operating systems, where processes are managed in the order they arrive, and in messaging systems where messages are processed in the order they are received.
