When you put things out of context, you will definitely be confused. The question asks for two services/applications that can cause slow down on a typical network. Chat, IM, web browsing etc. do not cause slow down because they do not demand constant connection to the other end. On the other hand, PC-based VoIP services and online video sites (streaming video) do use most of the bandwidth on a network.
So the comparison of bandwidth usage is between web browsing+chat applications and VoIP+streaming video applications.
