Picking the same nit: hardlinks are directory entries that point to the
same inode.  Example:

$ touch foo
$ touch bar
$ ls -li
 144958 -rw-r--r--    1 randy    randy           0 Jan 27 20:10 bar
 144957 -rw-r--r--    1 randy    randy           0 Jan 27 20:09 foo

Two files, two different inodes (the number in the first column is the
inode number), each with one link to the inode (the number in the column
after the permissions).

$ ln foo foo2
$ ls -li
 144958 -rw-r--r--    1 randy    randy           0 Jan 27 20:10 bar
 144957 -rw-r--r--    2 randy    randy           0 Jan 27 20:09 foo
 144957 -rw-r--r--    2 randy    randy           0 Jan 27 20:09 foo2

Note that foo and foo2 have the same inode number, but now the link
count for the inode is 2.
