What are the differences between queue and multiprocessing in Python?

In Python, a queue is a data structure that allows you to store and manage tasks, while multiprocessing is a module that enables concurrent execution of tasks across multiple CPU cores.

Can you explain how they affect performance?

Sure! Using multiprocessing can significantly improve performance for CPU-bound tasks by utilizing multiple cores, whereas queues are more about managing task flow and can introduce overhead if not used properly.

When should I use a queue instead of multiprocessing?

You should use a queue when you need to manage tasks that are I/O-bound or when you want to maintain order in task execution without the overhead of creating multiple processes.

Are there any downsides to using multiprocessing?

Yes, multiprocessing can lead to higher memory usage and overhead due to process creation and inter-process communication, which might not be ideal for lightweight tasks.
