How does code in one VS project reference code in another? Through "references"?

I avoid using multiple projects in my VS solutions because I don't understand them. This seems to be so basic a question that it doesn't show up in the initial google pages. So...

How does code in one project use code in a second project? If it is through references, what is the reference name of a project?

Any short explanations or links to documentation on this would be appreciated.

Thanks!

Thanks for the input. I think I need to back up one whole level of newbie on this. I'm using an asp.net website (not web application). When I set up a test solution, add two websites, then try to, for one of the websites, add>reference>solution>projects, I see no entries. Is this to be expected, and is it because a reference is to a dll, and websites don't have dll's? As you can see, perhaps I need a more elementary starting point for this subject.
