What are the differences between caching and buffering?

What are the differences between caching and buffering?

Caching and buffering are both techniques used to improve performance, but they serve different purposes. Caching stores frequently accessed data for quick retrieval, while buffering temporarily holds data during transfer to manage speed differences.

Can you give me an example of each?

Sure! An example of caching is a web browser storing images and files from websites you visit frequently. Buffering is often seen in video streaming, where data is preloaded to ensure smooth playback.

Why is caching generally faster than buffering?

Caching is faster because it retrieves data from a local storage location, reducing access time. Buffering, on the other hand, involves data transfer, which can introduce delays.

Are there any downsides to using caching?

Yes, caching can lead to stale data if the cached information is not updated regularly. It also consumes memory resources, which can be a concern in limited environments.
