Hey there kiddo!
Have you ever seen a traffic jam on the roads? It happens when there are too many cars on the road and they all want to get to the same place at the same time. Well, something similar can happen on the internet too. When too many people try to use the internet at the same time and want to access the same website or use the same app, it can create something called network congestion.
Network congestion happens when there is too much data being sent over the internet all at once, and the internet can't handle it all. It's like when too many people try to squeeze through a small door, sometimes they get stuck or slowed down because there's not enough space for all of them.
So what does network congestion avoidance mean? It means that we try to prevent network congestion from happening in the first place. Just like how we can avoid traffic jams by taking different routes or driving at different times, we can do similar things on the internet.
One way that network congestion avoidance happens is through something called "traffic shaping", which is like directing the flow of traffic on the internet. We can also use something called "packet prioritization", which means that we give more importance to some data over others so that it can get through the network faster.
Overall, network congestion avoidance is all about trying to prevent the internet from getting too crowded and making sure that everyone can access what they need without any hiccups.
