Final answer:
The missing location in the original ARPANET was the University of California, Santa Barbara. The ARPANET project started the development of the internet as we know it, with key contributions from Ted Nelson's hypertext concept and Tim Berners-Lee's World Wide Web.
Step-by-step explanation:
The Missing Link in the Original ARPANET
The original ARPANET consisted of four main computers, one each located at the University of California at Los Angeles, University of California, Santa Barbara, the Stanford Research Institute, and the University of Utah. This network, begun in 1969, marked the dawn of what would evolve into the internet we use today. The ARPANET was a groundbreaking project that allowed different computers to communicate on a single network, primarily for government and academic purposes.
The crucial developmental stages of the ARPANET led to the creation and adoption of new technologies and protocols that formed the basis of the modern internet, also influencing subsequent technological leaps such as the World Wide Web. Email, initially used for communication between researchers, was one of the early services it provided. As the network expanded, it became a prototype for the network of networks and introduced many to the concept of online connectivity.
The development of hypertext by computer scientist Ted Nelson, along with the vision of JCR Licklider and the later creation of the World Wide Web by Tim Berners-Lee, were instrumental in shaping the way we interact with digital content today. ARPANET's emphasis on research and open communication set the stage for the eventual commercial and public expansion of the internet.
