The TCP/IP protocol Brief History

The TCP/IP protocol suite allows computers of all sizes, from many different computer vendors, running totally different operating systems, to communicate with each other. It is quite amazing because its use has far exceeded its original estimates. What started in the late 1960s as a government-financed research project into packet switching networks has, in the 1990s, turned into the most widely used form of networking between computerrs. It is an open system in that the protocol suite and many of its implementations are publicly available at little or no charge. It forms the basis for what is called the worldwide Internet, or the Internet, a wide area network (WAN) of more than one million computers that literally spans the globe.

Also there is alot more than this about Tcp/Ip but it would take days to right it so this is just a brieft introduction to it.
