At the time, traditional communication networks -- like the nation's telephone system -- relied on analog, circuit-switching technology. Instead, there were a bunch of mini-internets. Other trains can't use that track at the same time as the first train because, ya know, they'd crash. Tim Berners-Lee, who first proposed the concept of a World Wide Web in 1989. documents on the network. Without IP addresses, data packets wouldn't be able to get to their proper destinations. cars on the highway.

IP, in comparison, is responsible for the formatting and addressing of the data packets being sent. In addition to carrying data, each packet contains destination information, so it knows where it's going.
