Any website you visit consists of thousands of media files and sometimes it may take a lot of time for browser application to load all the website’s content. The first time you visit a site, your browser duplicates original values of the website in order to make it load faster next time you visit it. This process is calledcaching.
When some changes to the website are made, it is necessary to clear cache of the browser, since some values of the website may be saved on the computer and browser will keep opening the old, cached versionof the website, so the changes will not be seen.
