The TCP/IP Stack

The TCP/IP Stack, or the internet protocol suite, is a set of communication protocols used by the Internet or similar networks. Originally resulting from research at DARPA (Defense Advanced Research Projects Agency). The TCP/IP stack has gradually grown to include a suite of protocols. (A protocol is simply a "set of rules", in this context, for governing networks)
