Chapter Summary
TCP/IP is an entire suite of protocols that provides data transportation, management, and diagnostic capabilities for networks that use it.
TCP/IP was started by the Defense Advanced Research Project Agency (DARPA). They were charged with developing a national communication system that could survive a nuclear war.
Later, their network, ARPANET, was turned over to the public, especially universities.
From there, the Internet grew into what it is today, a large world-wide commerce and communication network.
