html lesson on links

http://www.w3schools.com/html/html_links.asp

Just finished the lesson on links. I learned about anchors, which seem to be most useful for creating a table of contents or something similar.

I also learned how to link to a page and how to do a combined "link and open new window" link.

I don't quite get what the point of the name anchors is.

In summary, the tag "a" defines an anchor (link or a name).
