What are the performance differences between caching and non-caching systems?

Caching systems store frequently accessed data in a temporary storage area, which speeds up data retrieval. Non-caching systems, on the other hand, fetch data directly from the source every time, which can lead to slower performance.

Can you give me an example of when caching would be beneficial?

Sure! Caching is particularly beneficial in web applications where users frequently request the same data, like product images on an e-commerce site. By caching these images, the site can load faster and reduce server load.

Are there any downsides to using caching?

Yes, caching can lead to stale data if the cached information isn't updated regularly. It also requires additional memory resources, which can be a concern in resource-limited environments.

How can I implement caching in my application?

You can implement caching using various strategies like in-memory caching with Redis or Memcached, or by using built-in caching mechanisms in frameworks like Django or Laravel.
