A cache is a storage for temporary files that help apps or websites work more efficiently. While you work with some app, a system stores information on your device. An app will later retrieve the data from your device rather than re-downloading it from some distant storage. Local storage is preferred because it takes less time to retrieve data from there. As a result, you have better-performing websites or apps.
You can find cache everywhere:
- your devices cache the most repeated actions to perform them faster
- browsers cache images, logins, cookies to load websites faster and spare you time while logging in
- apps cache different data based on their function
However, if there is too much cache, it can load your system memory really quickly and result in worse performance and frequent crashes.
The solution to the problem is to clear the cache regularly. At the same time, it also means that every time you do it, you will have to log into all your favorite websites again and the system will need some time to gather some cache for better performance.
