   The content shifts to a slide titled "History of the internet." The instructor highlights that the history begins with "electronic computers in the 1950s" and mentions the "US Department of Defense" awarding contracts in the "1960s" for the "ARPANET project." She writes "1950 - 1960 -> ARPANET" and "1969" on the screen. She underlines the specific locations of the first message: "University of California, Los Angeles" and "Stanford Research Institute (SRI)." The final visible text discusses organizations that "oversee and standardize what happens on the Internet," listing entities like the "National Science Foundation" and "ICANN."

The lecture effectively bridges the gap between the user-facing applications of the internet and its technical and historical foundations. By starting with familiar activities like email and streaming, the instructor grounds the concept before diving into the complex infrastructure of IoT and wireless networks. The historical segment provides a chronological framework, pinpointing the 1950s as the starting point for electronic computers and the 1960s for the ARPANET project. The specific mention of the 1969 message between UCLA and SRI serves as a concrete historical anchor. The conclusion regarding organizational bodies like ICANN and the National Science Foundation adds a layer of governance to the technical history, completing the picture of the internet as a globally managed infrastructure.
