Can you explain the difference between prefetching and caching?
Sure! Prefetching is the process of loading data before it's actually needed, while caching stores data that has already been accessed for quicker retrieval.
Why would I use prefetching instead of caching?
Prefetching can improve performance by anticipating user needs, while caching is more about storing frequently accessed data to reduce load times.
Are there any downsides to prefetching?
Yes, prefetching can lead to wasted bandwidth if the prefetched data isn't used, whereas caching can consume memory.
Can you give an example of each in real-world applications?
Certainly! A web browser uses caching to store images and scripts, while a video streaming service might prefetch the next few seconds of video.
