What is cache?

Cache is a short-term storage for data called "cached files" that allows quick access to data already downloaded and saved by your device, making it faster to reopen apps or revisit websites. However, if too many of these files in your cache are bloatware or junk, the performance of your computer will decline.

 

The cache client will first check the cache for data access, distinguishing between a 'cache hit' when it finds the correct data and a 'cache miss' when it isn't. Managing data within the cache involves accepting or ejecting old data to make room for new data, which depends on caching algorithms, protocols, and system policies. Browser caching, which Safari, Firefox, and Chrome use, improves page performance by storing files for future access.

Primary types of cache

  • Browser cache: The browser cache downloads the content, graphics, and other media whenever you visit a website. Additionally, it saves these caches to your Mac cached files memory, allowing your device to access webpages faster each time you revisit them.
  • Application cache: Application cache, also known as user cache, stores files from different apps on your device, including files on apps from Apple and other companies, like photo or video editing apps.
  • System cache: The system cache in a Mac contains information about its main memory and processes, which the macOS system cache helps the Mac's CPU quickly find the information it needs, leading to faster loading times.
