Maybe someone knows... At one time (around last Summer) someone from this list posted an awesome link to a site that had a PowerPoint tutorial about the Internet origins and the backbone description, NAP's etc. Somehow I lost this link. I searched the archives but couldn't find it. There's probably others as well. Does anyone know of this one or even another one?
