What is Cache?
Cache is a small, fast place where a computer stores copies of data it expects to use again soon. It helps apps, websites, and devices load faster by avoiding repeated work.
In more detail
Cache is temporary storage that keeps frequently used information close at hand so a computer can access it faster next time. Instead of fetching the same data from a slower source over and over, the system saves a copy in cache.
This matters because it makes everyday tasks feel quicker and smoother. Web browsers use cache to speed up page loading, apps use it to open more quickly, and devices use it to reduce delays when repeating common actions.
Cache is helpful, but it can sometimes become outdated or take up space. That is why you may occasionally clear your cache if a website looks wrong or an app is acting strangely.
Examples
- A browser saves images from a website so the page loads faster the next time you visit.
- An app stores recently used data so it opens more quickly.
- Your phone keeps cached information to reduce waiting when switching between screens.
