Information Technology and Telecommunications (Information and Communication Technology / ICT) is the backbone of Web 2.0 applications. Information and Communication Technology Development phenomenal and the early emergence of web applications is the Internet. Internet that originated from research for defense and security and education developed into a business support device that is very influential. In connection with this Web 2.0 applications, there are some important events in the history of the internet.
Starting in 1957, through the Advanced Research Projects Agency (ARPA), the United States determined to develop an integrated communications network that connects between the scientific community and military purposes. This is motivated by the cold war between the United States with the Soviet Union (in 1957 the Soviets launched sputnik).
Internet's first major development was the most important invention of packet switching ARPA in 1960. Packet switching is the sending of messages that can be broken down into smaller packages, each package can be through a variety of alternative paths if one of the main damage path to achieve its intended purpose. Packet switching also allows the network can be used simultaneously to do a lot of connections, unlike phone lines which require a special lane to make a connection. So when the ARPANET into the national computer network in the United States in 1969, used a whole packet switching as a communication method that is used to replace circuit switching in a public telephone.
The development of the Internet both recorded in the history of the Internet is developing a network protocol layer which is famous for now is the most widely used TCP / IP (Transmission Control Protocol / Internet Protocol). Protocol is a set of rules to relate antarjaringan. This protocol was developed by Robert Kahn and Vinton Cerf in 1974. With a standard protocol and widely agreed upon, then the local network spread in different places can be interconnected to form a network giants even today span the globe. Network using Internet protocol is often referred to as the Internet network.
ARPANET networks become even greater since then and began to be managed by private parties in 1984, it incorporated more and more universities and commercial companies began to enter. Protocol TCP / IP into an agreed common protocol so that it can communicate with each other on this Internet network.
The third major development was the establishment applications Internet World Wide Web in 1990 by Tim Berners-Lee. Application World Wide Web (WWW) has become the content that awaited all Internet users. WWW make all users can share a variety of applications and content, as well as linking together the scattered material on the internet. Since then the growth of Internet users skyrocketed
