What are the types of queues?

What are the different types of queues in computing?

In computing, there are several types of queues, including FIFO (First In, First Out), LIFO (Last In, First Out), priority queues, and circular queues. Each serves different purposes.

Can you explain FIFO and LIFO queues?

Sure! FIFO queues process items in the order they arrive, like a line at a store. LIFO queues process the most recently added items first, like a stack of plates.

What is a priority queue?

A priority queue is a type of queue where each element has a priority level. Elements with higher priority are processed before those with lower priority, regardless of their order in the queue.

Are there any real-world examples of these queues?

Yes! A real-world example of a FIFO queue is a ticket line, while a priority queue can be seen in emergency rooms where critical cases are treated first.
