Dale,

I'm not sure. Here's what I think:

1. "Hyperlink" is short for "hypertext link."
2. Link is often (usually) just short for "hyperlink."

That is, sometimes "link" is synonymous with hyperlink.

HOWEVER, in computer science and even in web stuff, link has a more general meaning.

According to some references, the word link in web parlance can also refer to stuff that is "pointed to" but is not necessarily clickable. For example, if you were to bring in an image using img src, it might not be clickable (unless you put an href around it). In this view, all hyperlinks are links, but all links are not hyperlinks. That is, hyperlinks are clickable; links may or may not be clickable.

In more general CS terms, a link is a "pointer" or a "reference" to something else. A linked-list, for example is a data structure composed of "records" or "structures" in which each record has a "pointer" to the "next" record in the list.

So generally, a "link" is a mechanism for connecting things in different places.
