The History Of The Internet
The internet has come a very long way in the past 50 years. New inovations such as integrated software and hardware has changed the way that poeple view and obtain information today. The internet is a global computer network connecting millions and millions of users throughout the world. "It is a network connecting many computer networks and is based on a common addressing system and communications protocol."It has become one of the fastest growing forms of communication today(Encyclodpedia Britannica 1999). The Internet got started by the Defense Department as a Cold War experiment in the 1950’s. The government needed a way to relay information between tanks and headquarters so the ARPA (Advanced Research Projects Agency) sought a way to let signals from the battlefield reach a headquarters computer using satellites and radio signals. At this time our command posts were hidden underground in fear of a nuclear attack. "Paul Baran, working for the U.S. Air Force, developed a network that could reroute itself around damage caused by the impact of an Intercontinental Ballistic Missile by using 'redundancy of connectivity'". This meant that if there was a break in the network, the server would re-route the information on an alternate path through a new technique called 'packet switching'. "Packet Switching is a means of breaking up the message being sent into small packets which carry enough information to seek out its destination and sending them out separately towards the destination server. The message after being broken up would take separate routes to the destination and then be re-assembled by the computer at the server where the message was being sent." This was good because with more than one route for information to travel on, the enemy did not have one central point to target their attack to break the lines of communication and if there ever was a break in the line, the information could still travel through.(http:...
