I installed XAMPP whilst trying to set up a MediaWiki

You install software without any knowledge of it?
And was are not able to find any information what XAMPP is?
http://www.apachefriends.org/en/xampp.html
Can someone explain what XAMPP does so I can judge
whether I
need to keep it or not,
Among other things, MediaWiki needs a webserver software, PHP and MySQL.
If you don't have these things, you can install XAMPP.
But the question can't be answered at all whitout further information
about your PC/Server, your OS, and so on.
