That's why a common remedy for browser issues is clearing the cache. If there's something wrong with a file stored in the cache, it can cause the app to display data incorrectly, glitch, or even crash. A corrupted cache can cause the app to behave badly.Clearing the cache can erase the files and recover a large amount of memory. But some caches can grow exceedingly large and limit the free space on your device. In principle, a cache is a small repository of files used by an app. They can take up a lot of storage space.While modern software depends heavily on the use of caches, they have some disadvantages as well: Instead, the app only needs to download changed or new files.

If a copy of a file is stored in the cache, then the app doesn't need to waste time, battery power, and other resources downloading it a second time. There's a lot of efficiency in only downloading files once. Not only does this allow everything to run faster as previously mentioned, but in some cases it can allow apps to work 'offline.' For example, if you don't have internet access, an app can rely on cached data to continue to work even without a connection. To help improve performance, apps store recently and frequently used data to the cache. By storing local copies of web site files, for example, your browser only needs to download that information the first time you visit, and can load the local files on subsequent visits. The key benefit of a cache is that it improves the performance of the system. Benefits of cachesįrom a user standpoint, there are three main benefits to caches, including: Every app is different, though, and so the kind of data it caches will vary, but might include images, video thumbnails, search history, and other user preferences. Like browsers, apps save files and data they deem important so they can quickly reload the information as needed. Apps typically maintain their own cache as well.
