Data travels through the internet by getting broken into packets because it is to big to be sent as one big one. the packet has 2 ip addresses the person who sent it and the person who receives it. Routers are like traffic manages they send packets on towards their destination. The network has multiple paths so it is also fault tolerant because if the network is broken the routers send it another way so it gets to the destination quickly and all of this happens in a matter of seconds.
Computational thinking is a problem solving process that involves breaking down complex problems into smaller more manageable parts
