The forerunner to the Internet


In September of 1969, the first node of the ARPANET (the forerunner to the Internet) was completed at UCLA. The second node was established at Stanford. Soon, two more nodes were added, one at UC Santa Barbara and the other at the University of Utah.   Professional Web Design

These last two nodes incorporated application visualization projects which allowed the sharing of visual data such as scientific formulas. By the end of 1969, the four host computers were connected together forming the initial ARPANET that would eventually become the Internet. Computers were quickly added and work on host-to-host protocols (a set of rules for information exchange) and other network software was completed. Three years later in 1972,  Web Application Development In India

the first public demonstration of the ARPANET was conducted and electronic mail was introduced. All the while refinement on protocols was occurring. The ARPANET (Internet) was based on the idea that there could be many independent networks of arbitrary design connected to each other. So the Internet as we know it utilizes the idea of openarchitecture networks which permit all users to interconnect on an equal access basis regardless of the type of computer or operating system they use. This makes it possible for systems and networks of any type to communicate effectively as long as they use standard protocols. In 1980, the Transmission Control Protocol/ Internet Protocol (TCP/IP) was adopted as a defense standard and on January 1, 1983, all hosts were required to adopt the TCP/IP standard or be left out. During this time the ARPANET was
