Computer Networks
Does anyone really know what networking is? “In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come.
Network research can be traced back to around the 1960’s. “It was called the Galactic Network when it was first envisioned and described by J.C.R. Licklidder in 1962.” Dr. J.C.R. Licklidder and his colleague, Norbert Weiner of the MIT cybernetics department, were trying to create an electronic model of the human nervous system. They were trying to do this to see how computers and humans could interact. Leonard Kleinrock used Packet Switching with encoded data to address a message so that it could go to its intended "address" in 1961. Licklidder was able to design the “man-computer symbiosis” through the effective routing technology of Packet Switching. This meant that people could communicate with each other through a computer across a network. Licklidder called this mental model of this network, the Galactic Network. “The Defense Department of the United States was very interested in these concepts and, a year after he described the Galactic Network, Licklidder was asked to become the head of computer research at the Advanced Research Projects Agency (DARPA) in 1962” (Who Created the First Network). The main idea of this research was to develop a working network that went world wide to help military communications to move quickly across electronic digital paths. Lawrence G. Roberts took over for Dr Licklidder as the head of computer research at DARPA. He designed the first long distance network based on Licklidder’s Galactic Network in 1965. “On a cold war kind of day, in swinging 1969, work began on the ARPAnet
