What you're calling a "link", most people would call a "path" or
"chain".  A link, in this context, is a direct connection between two of
the nodes in the path.  Each of the hyphens in your diagram is a link;
each complete line of nodes is a path.

I've no idea what you think is meant by the phrase "A chain is only as
strong as its weakest link", since you seem to think "chain" and "link"
are the same thing.

However, though your terminology is confused, you are correct that a
shorter path (or chain) through the web is generally stronger -- simply
because there are fewer possibilities for a weak link along the path.
