What is cache?

When a webpage is viewed, the files that make-up the page are copied (downloaded) to your computer.

To make it faster to view webpages, a web browser can store or cache these files. Once files are in-cache, the browser no longer needs to download them each time the webpage is viewed, it simply uses ‘the ones it prepared earlier’.
