Internet stands for Interconnection Network that connects the networks (network) between computer. While the network itself is defined as a communication of data between computer systems. Examples of the most common computer network we find for example a LAN (Local Area Network) that connects computer which is in an area or specific location such as offices, schools, companies, and universities, which are also commonly called intranet. Internet is a source of information that reaches the whole world. Since the globalization ofthe range connection, the internet can be defined as a network globally connecting thousands and even millions of computers loaded with the contents of the diverse as education, government, business, culture, and technology. This internet allows individuals to interact and communicate with the other through computers from around the world at considerable cost affordable. The history of the Internet began when the Department of Defense, U.S. Defense Advanced Research Projects Agency (DARPA) decided to conduct research about how to connect a computer to form organic network in 1969. This research program known as the ARPANET. On 1970, more than 10 computers were successfully connected to each other so they can communicate with each other and form a network. In 1972, Roy Tomlinson managed to complete the e-mail that he created a year earlier forthe ARPANET. E-mail program is so easy it immediatel y became popular. In the same year, icon @ also introduced as an important symbol that shows the "at" or "on". In the year of 1973, ARPANET computer network were developed outside the United States. Computer University College in London, was the first computer that is in outside the United States that are members of the ARPANET. In the same year, two computer experts that Vinton Cerf and Bob Kahn presented a larger idea, which became the forerunner of the Internet thinking. This idea presented for the first time at the University of Sussex. Historic day following the date of March 26, 1976, when the Queen of England successfully send an e-mail from the Royal Signals and Radar Establishment at Malvern. One year then, more than 100 computers on ARPANET joined to form a network or network. In 1979, Tom Truscott, Jim Ellis and Steve Bellovin, created the first newsgroups called USENET.
