In the directory entry for that file. The directory entry contains the
inode. That file simply points to that inode. That it is the same inode
that some other entry points to as well, well,that is what a hard link
means (in the inode structure is a number which says how many directory
entries point to it.

That is a soft link. Here you just have an ordinary directory entry
which points to  the intial inode.

NO. You have to uncompress the tarball, then search through the huge
contents of that tarball to find the entry you want. That is slow. Very
slow.
