What Is Broadcast Domain?

You can tell if you're in a broadcast domain by hearing what's happening in the other room. If you listen to your neighbor shouting at his dog, you're in the same broadcast domain as him and his dog. When it comes to computers, a broadcast domain is a group of computers that are close together and share the same network address. In this case, we're talking about people who live together in one house. They're all on the same network, so they can see each other's activity and hear what's happening in the other rooms at any time. If one family member wants to talk to another who isn't home now, however? They'll have to wait for them to return before chatting about how annoying their little brother is (most likely). Broadcast domains help prevent network congestion or latency issues. Separating the network into multiple broadcast domains will help reduce collisions, which are possible when a bridge receives numerous requests from various nodes simultaneously. Implementing network segmentation will also help reduce the size of your network, which will help reduce overall latency. A Broadcast Domain is a group of nodes that are in the same broadcast domain and can exchange data frames with each other. A Broadcast Domain provides high-level communication and reliability via a simple Ethernet connection. A node is in the same broadcast domain as its neighbors if it can hear them and thus receive data frames from them. All nodes in a hub and spoke topology are in the same broadcast domain because they are connected to each central hub. The node must check whether it is the intended recipient of an incoming frame before accepting any addressable data frames from other nodes. If a node receives an addressed packet, it must respond with an appropriate response packet or discard the transmitted frame without responding. A broadcast domain is like a private party. You have to be invited to come, but once you're there, everyone is your friend, and you can talk to anyone.
