There are three "levels" or types of deletion:
- Blanking --> simplest, anyone can do this and view the blanked content in
the history 2. Deletion --> admins can do this easily, other admins can see this and it is shown in a public log 3. Oversight --> [[m:Hiding revisions]] revisions are *permanently* removed from the database by those with the "oversight" permission, can only be re-added by developers (I think root). However, there is a private log that shows a *little* information. Oversights (people with the oversight permission) are assigned by ArbCom.

Don't forget level 4: "Deleted off the hard disks completely." IIRC, everything that was deleted (#2) before something like March 2004 was accidentally completely deleted (#4) by the devs, and of course we only comparatively recently got true #2 deletion for images (that is, allowing for admins to undelete).
