The ARPANET (Advanced Research Projects Agency Network) created by ARPA of the United States Department of Defense during the Cold War, was the world's first operational packet switching network, and the predecessor of the global Internet. Packet switching, now the dominant basis for both data and voice communication worldwide, was a new and important concept in data communications. Previously, data communication was based on the idea of circuit switching, as in the old typical telephone circuit, where a dedicated circuit is tied up for the duration of the call and communication is only possible with the single party on the other end of the circuit. With packet switching, a system could use one communication link to communicate with more than one machine by disassembling data into datagrams, then gather these as packets. Not only could the link be shared (much as a single post box can be used to post letters to different destinations), but each packet could be routed independently of other packets. A form of packet switching designed by Lincoln Laboratory scientist Lawrence Roberts underlay the design of ARPANET. From Wikipedia under the

Q. ARPANET was the original backbone for what we now refer to broadly as "The Internet." The backbone was constructed to allow for decentralized military operations - ie. if one city or base was bombed, another base would still have control of critical weapons and defenses. Today, the Internet has become more of a communications medium than a military network. While the Internet was designed with the intention of security and safety from military attack, the Internet presents new security threats. What risks do we take when accessing the Internet? What types of technological "attacks" can occur? Has the advent of the Internet made as safer or more vulnerable as a nation? Why?
