- There may be a difference between the version of a website (Pinnacle Series for example) cached (stored) on your computer and the version that you're loading from the web. This conflict can lead to weird glitches, and clearing your cache can help when nothing else seems to.
What is a Cache?
A cache is a special storage space for temporary files that makes a device, browser, or app run faster and more efficiently.
- After opening an app or website for the first time, a cache stashes files, images, and other pertinent data on your device.
- Cached data is used to quickly load an app or website for every subsequent visit.
- Every web browser, whether it's Microsoft Edge, Chrome, Firefox, or Safari, maintains its own cache.
- Apps typically maintain their own cache as well. Like browsers, apps save files and data they deem important so they can quickly reload the information as needed. 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.
Benefits of Caches?
- They make everything run faster. The key benefit of a cache is that it improves the performance of the system. By storing local copies of website 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.
- They save data. To help improve performance, apps store recently and frequently used data to the cache. 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.
- They store data for later use. There's a lot of efficiency in only downloading files once. 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. Instead, the app only needs to download changed or new files.
Downsides of Caches?
- A corrupted cache can cause the app to behave badly. 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. That's why a common remedy for browser issues is clearing the cache.
- Caches can prevent apps from loading the latest version of a web page or other data. In theory, apps are supposed to only use the cache to display files unchanged since the last visit. That doesn't always work, though, and sometimes the only way to see the latest version of a website or other info is to clear the cache, so the app is forced to download everything anew.
What happens after clearing the cache?
- The advantages of clearing the cache include freeing up previous storage space on your computer and eliminating any files that might be causing it to misbehave.
- Clearing the cache also eliminates the files that are designed to make your computer run more efficiently. For example, clearing a browser cache typically means you'll have to log in to all your favorite websites all over again, and you'll lose any special customizations or personalization you had there, including the contents of shopping carts or baskets.
