The Internet is a "network of networks" best known as the global network the World Wide Web is run on. Many people mistakenly call the "World Wide Web" "the Internet," however this is not actually the case. The Web is the Internet's best known and front-facing service, however there are literally hundreds of different protocols, applications and services that run over the Internet.

The research which led to the Internet was funded initially by the United States' Defense Advanced Research Projects Agency (DARPA), which was established in 1958 as the first U.S. response to the Soviet launching of Sputnik. The first functional networks between individual computers were created in the early 1970s. Many educational institutions and corporations began joining the network, and in 1983 all nodes on the so-called DARPA-net changed over at once to a new protocol, TCP/IP, which is still in use on the internet today. The fundamental transport protocol for the internet has not changed substantially in more than twenty years. However, it is on the verge of being "upgraded" in the near future, with a movement from version 4 (IPv4) to version 6 (IPv6) of TCP/IP.
