The Internet as we know it today would not be in existence if it weren’t for the creation and groundbreaking research attained from the original network, the ARPANet. In order to better understand how the Internet came to be, it is important to look into the development and lifespan of the ARPANet. It can be argued that the original idea of this original network wasn’t that of a single idea, but ideas from collaboration of a lot of people. For the sake of historical reference, Leonard Kleinrock proposed his PhD proposal about modern data networking on May 31, 1961. Little did he know that he would be instrumental in the creation of a worldwide computer network that would revolutionize the way most people (and machines) communicate. In the words of Bob Taylor, director of the Information Processing Techniques Office (IPTO) who also worked with the director of the U.S. Department of Defense Advanced Research Projects Agency (ARPA at that time) at the ARPANet’s conception, "The ARPANET was built to permit ARPA-supported computer researchers to share common interests without geographical limits." Initially, in mid-1960’s, three institutions had specific roles important to the creation of the ARPANet. The company BBN was tasked to create a connector between the network and computers in the network, or Interface Message Processor (IMP). These connectors can be compared to modern day routers used to connect to the Internet. SRI International was tasked to become the Network Information Center. They were responsible to track all computers on the network and became the original Domain Name System (DNS). UCLA (Leonard Kleinrock was a professor at UCLA) was tasked as the Network Measurement Center. Kleinrock and his UCLA group had the responsibility to research, track and improve the flow of data over the network. Although there were still bugs to be worked out, an IMP was installed at UCLA in early September 1969. Another was then installed at SRI in early...
