konqueror usb media:/sdc1/ but mounted on /media/sdc1

[jackson byers <byersjab gmail com>]

an external usb disk is  mounted as
/dev/sdc1 on /media/disk-1 type reiserfs (rw,noexec,nosuid,nodev,sync)

which mount occurs on double clicking of the usb icon on the desktop

but the konqueror window which also pops up 
shows in its location bar  
    media:/sdc1/

here there is 
no leading  /  on  media
no  /disk-1    following  media
and no /dev  leading the /sdc1


is there documentation explaining these differences?
is this   media:/sdc1  ever used by users as an alternative location  syntax?
thanks for any help

this is on FC5
