Computer Scientist Explains the Internet in 5 Levels of Difficulty | WIRED

The internet is the most technically complex system humanity has ever built. Jim Kurose, Professor at UMass Amherst, has been challenged to explain the internet to 5 different people; a child, a teen, a college student, a grad student, and an expert.

Mr. Kurose's textbooks are legendary. He taught for millions. A good man.

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

As a Dad of a youngster I have to say this guy is an amazing teacher when dealing with the first young lady. She was so bright

I’m a UMass Amherst student and I’ve taken classes with Jim. He’s a amazing professor!

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.

I don't know about you but that Knock Knock joke was such a nice analogy and really stresses what a good communication skill this Prof has.

I have Mr. Kurose's textbook as an electrical engineering student and it is excellent. He is an amazing teacher.

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.

I love how I learned the most at level 1 with the child for some reason 🤯

Used Computer Networking: A Top-Down Approach in my networking course in college. Great book written by Dr. Kurose, thank you!

[pagemaestro]

I took a course in uni where I read Kurose's book "Computer Networking". It's so heartwarming to see him so passionately break down the complex procedures that go into understanding the internet on a level that non-tech savvy people can understand. I have respect for people at the top of their field, but an immensely larger respect for people who have the capacity to educate even the least knowledgable people about their field. Way to be, Jim, way to be<3

He was my professor. The class was awesome.

[danitajaye]

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 am a Comp Eng undergraduate in Brasil and I have been following professor Kurose's classes! He really is a big reference in the area. Besides being an amazing teacher!

[jadeyjung]

the most "wired" talk of this series

[programmersenja]

The professor sure is outstanding but Skylar is indeed very smart kid for that age

[janetf]

Prof. Kurose is the best listener I've witnessed in ages.👏👍✌

[umaodihirin]

In 10:35 I believe the uni student was referencing the OSI model which has 7 layers and explains theoretically how devices exchange data over the internet. As an IT Pro with 10 years od exp, I had some great takeaways here. Amazing video 👏🏾

[quanleanh]

The core CS fundamentals: Networking, OS and basic DataStructures & Algorithms are always the most interesting subjects. Sadly it took me years to finally understand this simple fact.

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!
