TCP/IP is close to 20 years old. It was developed as part of one of the oldest attempts in establishing a computer inter-network, now known as the Internet. The protocol has out lasted many more recent and modern protocols and by now many of these more recent networking protocols have been forgotten. TCP/IP and the concept of the Internet is elegant in its simplicity. Largely because of its ubiquity and its simplicity, this old TCP/IP based Internet has become the global fabric uniting much of modern life and is now the basis for much of the hot new “High Technology” of today.
