Watch this clip to see software engineer Lynn Root and co-creator of the internet Vint Cerf explain what keeps the internet running reliably.

When information is sent on the internet, it is broken down into packets that are able to take a number of routes to get from one computer to another. Why might this be important?

Why does Vint describe routers as being like traffic managers?

And what does the transmission control protocol (TCP) do to ensure all your data is delivered properly?
