/wiki is an absolute *server* path (i.e. *from the point of view of your web host*), it's like the "/" refers to the root of your domain (i.e. the http://www.domain.org), not to the root of the physical thing you also call a server (like in /home, /boot, 
/usr,...).

/wiki can be seen as a sort of relative path from the point of view of your web directory (/opt/lampp/htdocs/) on the physical computer.

For instance if you consider the html tag "img",  you can use src="http://yourdomain/wiki/image.png" or src="/wiki/image.png" which are absolute *server* path but (normally) you shouldn't be allowed to use src="/var/www/wiki/image.png" which is absolute 
*computer* path

you can also use src="./image.png" or src="../../anotherfolder/image2.png" which are relative *server* path (--> again, relative to the location of the current page *from the host point of view*, not from the physical point of view)

I hope I haven't been too "unclear" nor incorrect.
