What is stored in your computer's cache
Apps / software What is a cache?
If you have ever had errors when opening web pages in the browser, you have probably already been suggested to clear the cache. But what is a cache anyway and what does the deletion process bring? In this post, we'll explain everything you should know about the cache.
What is the cache?
A cache is a reserved space that collects temporary data. This is created either locally on your computer, smartphone or other media in order to load websites, browsers or apps more quickly. For example, if you regularly access a website, your browser saves its content in the cache. This cache is not visible to you as a user and is created by the system. If you call up the page again, the content will load faster.
The cache is a memory that facilitates renewed access through local intermediate storage on your PC or smartphone. This means that not all data is downloaded anew each time it is opened, but rather quickly read from your own hard drive.
Caches have three key advantages: First, they improve system performance by making everything load faster. Second, applications can sometimes work offline if you do not have Internet access because important data is cached. And thirdly, data is saved for later use so that the data only has to be downloaded once in a resource-efficient manner. If you have to reload the data, this consumes battery or computing power unnecessarily. Despite the advantages, the cache can also cause problems. The reason for this can be incorrect data in the cache or that the cache simply takes up too much storage space. Only one thing can help: Empty the cache!
In order to better understand where the cache occurs in everyday applications, we have put together the three most common example cases below:
Caches are found in both software and hardware. One example is the CPU cache. This hardware cache is used by the central processing unit (CPU) of your computer, laptop or smartphone to reduce the average access time to data from main memory. The CPU cache is a small memory that backs up copies of data from commonly used main storage locations to ensure fast execution of instructions. You can view the cache via Disk Cleanup on Windows. The cached files can be deleted if necessary.
Not only the browser cache is relevant in everyday life - apps also save temporary files in the cache so that they can be quickly reloaded when needed. Images, videos, search history or login data are saved here.
