The Internet, a global computer network which embraces millions of users all over the world, began in the United States in 1969 as a military experiment. It was designed to survive a nuclear war Information sent over the Internet takes the shortest path available from one computer to another. Because of tliis, any two computers on the Internet will be able to stay in touch with each other as long as there is a single route between them. This technology is called packet swithing. Owing to this technology, if some computers on the network are knockcd out (by a nuclear explosion, for example), information will just route around them. One such packet-switftfng network which has already survived a war is the Iraqi computer network which was not knocked out during the Gulf War.
