    The hair, the glasses, and the blue shirt all make him look like he works at genius bar. The only difference is he’s actually genius.

    The grad student should look into PKI for the IoT devices. Then you wouldn’t need to constantly setup when you move.

    It’s all BS because my 5G network is as slow (and sometimes slower) than my old 4G network.

    If you want to learn more: I can highly recommend typing his name into youtube. He has a quite extensive series explaining the internet in more detail!

    wonderful! The speed of change is amazing. I’ve been in IT since 1980, and you can’t even fathom really how very far things have come. It started changing, and then changes happened faster and faster, exponentially. I’m happy to be a newly retired developer, lol. Enough learning new language/processes, etc., every year. 🙂

    I’m in love with the college guy. He seems nice, kind, smart and probably has huge D.

    The way he described the internet to Skylar was actually REALLY good. I’m impressed. Kinda surprised Nicholas didn’t know about ARPANET, especially as a comp sci student. Also, Nicholas probably watched this video when he mentioned the “seven keys to the internet” –

    The Internet was not centrally planned, even if government did some early research, it didn’t plan out any of what the Internet is today.

    Hearing about the number seven reminded me of the OSI Reference Model.

    I’m a network engineer and I wanted to put here a cool little bit of information for you all.
    The internet mostly runs on a protocol called TCP (transmission control protocol)
    This protocol is part of the 7 layers of the OSI (open systems interconnect) model.
    the layers are 1. physical 2. data 3. network 4. transport 5. session 6. presentation 7. application
    When I was first learning about these layers I came up with the perfect acronym to remember it and i’ve never forgotten 25 years on.

    “People Don’t Need To See People Anymore”
    Physical data network transport session presentation application
    PDNTSPA
    Because of the internet – people don’t need to see people anymore.

    The Internet is not something you just dump something on, it’s not a big truck. It’s, it’s a series of tubes. TUBES!

    With all due respect to your last guest, 5G is not about coverage. If anything, 5G is significantly less coverage than previous generations especially when you get to 5GUW.

  41. ALL THINGS TO ALL MEN

    November 24, 2022 at 1:17 pm

    I like how as he moves up the levels it’s less of him explaining and more asking questions and listening.

  42. Jan Kadera

    November 24, 2022 at 1:34 pm

    Level 2
    Q: how is it so fast?
    A: it’s like a route system and there are intersections…

    Just like when I was in college. Brilliant and useful answer…just not to my question.
    And then in the test: if router A have a throughput of X and line B have a length of Y, what is the reliability of your neighbours HDD?

    Sorry not Sorry, How to explain to a 5 years old in 10 sec: Internet is a network and language between compters to talk with other compters and gives each other things such as movies, music tracks, documents and web pages. BAM it took this professor almost 1 min until he says “internet is a network to exchange information”. Next stop – explaning to a 5 yo abstract meta comcept information .

    The six year old had a better idea of BGP or even OSPF than the teen when she alluded to redundancy. LOL. Level 3 seemed lost at the end in regards to contention ratios. It’s amazing because I’ve got a three year old nephew and I feel like by the time he’s my age, he’s gonna be way far ahead of where I am now, just due to the technology he’s grown up with.

      funny isnt it because the 9 year old has been around it longer, even the 15yo probably didn’t have internet access until she was 10-12

    When the undergrad said “7 keys” I immediately figured he was conflating the 7 layers of the OSI model with something else. Surprised the professor didn’t also immediately hear 7 and go to the OSI model.

    Dr. Kurose is a Takumi in network world. If you are studying in UMass, I recommend you to take his INFO203 as a network intro course.

  68. LoneStar Not

    November 27, 2022 at 2:47 pm

    @Tony Patrick, yeah, “7 keys” seemed a lead-in to … maybe Prof.Kurose didn’t want to leave the very general audience.

    This was cool to watch as a UMass alum 🙂 Clarifying question: ‘flattening’ of the internet is bad, right? Good in the sense that you might have to jump fewer networks / speeds might be faster, but bad because then ownership is less decentralized?
    Also, would love to see the two experts explain VPNs!

  71. SALESPRODUCTIONS

    November 28, 2022 at 4:22 pm

    Skylar ( the 1st girl ) already understands the internet – on her own – and is very bright. She deduced the point of it right away – ( multiple nodes in case of one not working ) and even understood conservation of energy / time and productivity goals. She likely understands the internet WAY better than the majority of the population. ( I will also point out that one of the original goals was to create something that had so many nodes on it that people could still communicate in the event of a catastrophe ) See DARPA etc . . You could also see the interviewer laughing and being a bit shocked at her deep level of understanding she worked out on her own and mentioned right away.
