What are the cache, cookies and history used for?

Whenever you visit a website through using your web browser, your browser stores (or “caches”) a copy on your computer in a cache. The copy is typically stored for several days. That way, when you click the back or forward button or come back to the website after a few days, the page will load more quickly since you don’t have to download the files again.

A cookie is a file that stores data for a particular website, so that it can remember your preferences and information the next time you visit the site.

A browser’s history is a log of the sites that you’ve visited.

Your browser will typically remove all three of these things after a certain period of time, but it can help your browser run more efficiently if you clean them out periodically.

I have also found that by periodically removing these files, will decrease the chances of getting spyware or malware on your computer.  This is because some forms of spyware are embedded in these files.  Spyware & malware is also one of the leading causes of a slow computer.
