The Internet has its roots in ARPANET, a network started by an agency of the U.S. Department of Defense in 1969. ARPANET was created to allow scientists at different locations to share information. Although it consisted originally of four main computers, as researchers and others realized the benefit of using ARPANET, the network experienced phenomenal growth; by 1984, it linked more than 1,000 individual computers. In 1986, the National Science Foundation (NSF) connected its huge network, called NSFnet, to ARPANET. This configuration of complex networks became known as the Internet. Today, more than one-half billion people around the world use the Internet. The World Wide Web emerged in the early 1990s and is one of the more widely used services on the Internet. Tim Berners-Lee generally is credited as the creator of the World Wide Web. After working with various types of computer programs, Berners-Lee recognized that although computers could store and process information, they could not store random associations between disparate things (something the human brain is able to do).
