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. 🙂

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” –

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.

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.

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.

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!

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.

It’s funny how college undergrad level is the same as it was in the late 90s. Back then you’d know the basic nuts and bolts of the network, provided you were paying the slightest bit of attention, simply because it was in its infancy, and there was a bulk of highly visible information about how the system worked. Kids today haven’t been told about what’s under the hood.
