collision vs. broadcast domain: Hub, Switch and Router

[@railpressureflip]

Very well explained. Absolutely love the usage of illustration and animation, where everyone else out there just jabbers on technical jargons and expects everyone to understand. Well done, great video!

[@sunnyclassroom24]

Thank you very much!

[@mattjoe67]

Yes, Sir, those professors at colleges are a bunch of idiots and they DO NOT want you to learn fast and quick, they want to feel important, no matter how many times ask them a question, they take me through crocket and confusing roads, which I never understand them, when I visit the youtube, takes me 5 minutes to understand It, and thanks to these people and youtube.

[@theMahtahild]

Wow this is a life saver for me! I'm in a somewhat advanced cisco class where I am expected to have known this already, but it never really clicked until now, thanks to you breaking it down and showing how they work together and their purposes for separating the different layers. My only question is: So does each LAN (purple, red, blue in your example) have only one IP address, and then once the packets have been sent to that IP address, routing from that point on is done solely by MAC address? I just want to make sure I am understanding correctly.

[@alejocayon8525]

jajajajajajaj "I am expected to have known this already," metiendo embustes en la empresa y no sabe un carajo jajajaja pobre infeliz !

[@sameera12]

Hello sir, you got an answer? According to this lecture, kzbin.info/www/bejne/f4HZip2OeNiHnZo at 28:07, he said we will have 1 global ip address that of router, mac addresses and port numbers are used to route the packets in LAN Please correct me if I am wrong Thanks!

[@RowanWarren78]

Oh, this finally makes sense! I was thinking of them as working against each other equally, and not being separate things setup in a tiered fashion more like the OSI--thank you!!

[@arno.claude]

Hub: Everything you say, gets heard by everyone. Switch: Only the receiver receives your messages. Except if you do a broadcast, in that case, also everyone hears you. Router: Only the receiver receives your messages. Except if you do a broadcast, in that case, only everyone inside your broadcast domain hears you.

[@charlesriley4937]

Such a wonderful explanation to the process! This helped a lot! Thank you!

[@zero6onefivebe]

Great tutorial! Thanks! Maybe the half-duplex has to be mentioned in the Hub section.

[@sunnyclassroom24]

Thanks a lot!

[@seetsamolapo5600]

Hub - operates at layer 1 - when it gets a signal from one node will send it to the rest of the nodes connected Switch - operates at layer 2 - gives every conversation/communication the full bandwidth of the network - only destination node hear communication from source node - connections can happen at the same time without collision this switches separate a collision domain - when communications pass through the switch for the first time it copies their source nodes' MAC addresses and stores it in a Source Address Table - It still gives every conversation full bandwidth even when additional nodes are added - thus separates collision domain but creates broadcast domain - group of nodes that can hear each other by broadcast Routers - operate at layer 3 - separate collision domains and further separate broadcast domains

[@yvesallen5]

The topology at 1:53 is just one large collision domain, because it is just one LAN, so the whole diagram should be grayed out and not just certain portions I believe.

[@sunnyclassroom24]

Thank you for pointing that out.

From what Ive learned so far, it kind of seems like a HUB would be very inefficient and a potential hassle. why do we still use them when a switch would be a better option it seems?
