What is browser cache?
Browser cache refers to temporary web content storage that helps websites load quicker. Caching works by saving static files in the local computer memory. This reduces the number of requests sent to the web server that holds the actual files – meaning that your computer loads the page content from local storage, instead. That way, by caching elements such as HTML, CSS, JS, and images, the browser dramatically reduces the load time of a website and the overall resource usage.
What is cached data?
A cache is a term used to describe temporary storage. Cached data, on the other hand, is the collection of items saved within the cache storage location. Whenever your browser is requested to look up a specific file, it first checks if the resource is available locally. If not found, the browser sends a request to the corresponding web server and saves it as cached data depending on the file type.
What does clearing the cache do?
Clearing the browser cache removes all the data kept within the temporary local storage. As a result, once you first access a website after clearing all the cache, it will take longer to load. This occurs because no resources can be retrieved locally and all of them will have to be delivered by the corresponding web server.
Why clear cache?
The files gathered within the browser cache can take up quite a lot of disk space over time. This may result in your browser working slower than usual and utilizing additional resources. Furthermore, outdated resources within the cache may cause you to see incorrect content. For example, you may have difficulty viewing new changes and updates made on a website. That's why clearing the browser cache from time to time helps you access only the most up-to-date data.
