A foundational knowledge of network architecture starts with the concepts of broadcast domains and collision domains. In this video, you’ll learn how modern network design has eliminated collision domains and how you can minimize the impact of broadcasts through the use of properly engineered broadcast domains.

half-duplex is like a party line phone! Yes...I'm old enough to remember party lines. I got started on this networking stuff a little late.
Very precise and clear. Thank you very much sir
Are broadcast domains also constrained by subnetting and VLANs?
yes, when a broadcast is sent through out a network, it will stay within that vlan or subnet. Broadcast on vlan 1 will not be heard on vlans 2 ,3 and so on.
I second that. Information sent between 2 VLANs needs to be send on layer 3, using IP routing
it's silly to ask, but in real life do we use hub and switch in our home? I mean I have heard about router a lot, never heard about hub and switch in real life. for example, in our home, we have one main router which is connected to phone line to provide internet connections, then we add few devices which I think called a sub to provide strong signals on each apartment or room. So which one is hub or switch in among these? or is it only use in a corporate environment?
Hubs are no longer used, but the router in your home probably has multiple switch ports on it.
@PEACE 144 Switches don't only have one broadcast domain, vlans do. Your switch has only 1 vlan by default, so if you don't configure multiple vlans you will only have one.
so if a blue side computer wants to broadcast something on the red side, they'd have to send a package that targets every single one of those red side device's mac address?
A computer in one broadcast domain can't broadcast to another domain. They can only broadcast to other devices in their same broadcast domain.
@@professormesser So one domain can't contact the other?
@@masafulgur4967 Broadcasts don't leave the broadcast domain. Other types of traffic may be routed to another broadcast domain, but this conversation is specifically referring to broadcast traffic.
