When you download a web page the data is cached. This means it is stored temporarily on your computer. The next time you want that page, instead of requesting the file from the web server, your web browser just accesses it from the cache. That way the page loads more quickly.

However, if the web page is updated frequently, as may be the case with news, sports scores or financial data, you won’t get the most current information. By using the Reload button on your browser, this data is updated by downloading fresh data from the web server.
