Introduction:
When the ARPANET was designed in the late 1960s, it was outfitted with a Network Control Protocol (NCP) that made it possible for the very different types of hosts connected to the network to talk with each other. However, it soon became clear that NCP was limiting in some ways, so work started on something better. The engineers decided that it made sense to split the monolithic NCP protocol into two parts: an Internet Protocol that allows packets to be routed between the different networks connected to the ARPANET, and a Transport Control Protocol that takes a data stream, splits it into segments and transmits the segments using the Internet Protocol. On the other side, the receiving Transport Control Protocol makes sure the segments are put together in the right order before they're delivered as a data stream to the receiving application. An important implication of this approach is that unlike, for instance, a phone connected to a wired or wireless phone network, a host connected to the ARPANET then and the Internet now must know its own address.
