What is cache?

A cache (pronounced CASH) is hardware or software that is used to store temporary data in a computing environment.  This is used to improve the performance of recently viewed websites, and helping you load them faster the next time you go visit that site.  Cache is frequently used by the computer, programs, and web browsers.  When you visit a website, the requested files are stored in your browser's cache.


Why does your computer need cache?

  • Cache reduces lag, thus giving higher performance for a computer or program.
  • Data can stay permanently in your computer, thus eating up the speed your computer will run.


Why should you clear your cache?

Clearing your cache forces your browser to retrieve the newest version of websites, something that should happen automatically but sometimes does not.


How do you clear cache?

There are some programs you can download that aim to clear cache and browsing history (as well as saved passwords if you aren't careful).  Though it's recommended that you manually remove cache yourself, sometimes using these programs can help attack multiple browsers at once.
