Guys, I'm wondering what actually does "Web interface" component mean during installation Transmission under Windows?

I can see Web UI either with installed "Web interface" component and without this one - and Web UI is the same in both cases.
For all I know, deamon actually enables access via http and it doesn't care by which exactly mean it would be done: via desktop GUI client or any web browser.
So I'm looking for any explanations what actually does that "Web interface" component mean?
Thank you so much!
