Asymptotic bandwidth is like a measure of how much information can travel through a tube. The tube is like a highway that can only fit so many cars on it at once. The more cars you try to fit on the highway at one time, the slower they all go.
Now, imagine if you had a really big highway where you could fit a lot of cars at once, and they could all go really fast. That would be like a high asymptotic bandwidth.
But sometimes, even if you have a big highway, there might be a lot of traffic that you have to share the space with, so things slow down. That's kind of like interference or congestion in the network that can affect the asymptotic bandwidth.
So, when we talk about asymptotic bandwidth, we're talking about the maximum amount of information that can travel through a network when everything is working as smoothly as possible. But just like with a highway, there can be factors that slow things down or reduce the amount of information that can be transmitted at once.
