Caching
Keeping a temporary copy of something so it can be retrieved faster next time
What's it for?
Makes something faster to retrieve by keeping a temporary copy ready for reuse.
For example…
A website caches product images near users so repeat visits load them without fetching the originals every time.
A reporting website keeps a temporary copy of information it uses repeatedly, so pages can open faster instead of asking the main database for the same data every time
Think of it like…
A small fridge upstairs by your desk, keeping things from the main fridge downstairs so they’re quicker to reach
