We can start to think about things like toruses, where we'll take the end here and connect it around. And we can actually make some more advanced versions of these. But you couldn't do that when everyone was shouting to each other, as only one, one, entities allowed to talk on this network at a time. Let's say one is talking to two, and three is talking to four at the same time. And now you can have nearest neighbor communication. So sort of the next step away from something like a, a bus is actually something like a pipeline bus, where you start to put registers in along the way. It may not have the best bandwidth, and it might impact your clock frequency, so it might even impact your latency, depending on how you go about implementing one of these things. And it is, it is a type of interconnection network. So a multi-drop bus, where everyone just sort of screams, is a broadcast network. And actually buses are a type of interconnection network. So far, we've, in this class, we've been talking about buses. Now we went through this really fast, but I wanted to go into a little more detail here. So we started last time, this is where we left off was talking about topologies.
