@MrJoegotbored Год назад

For other readers who may be interested, this is described by some as a Socratic teaching method. It's a practice widely employed in professional programs of study, such as law, medicine, and computer science, but also by some schools at the undergraduate level. The idea is to teach the student how to learn by using a series of ever more precise questions to guide them to an inescapable conclusion. It's extremely effective, especially at higher levels where students may know quite a bit, sometimes more than the professor in certain areas of the subject.

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.

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 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

@yaknowjoshua1451 14 дней назад

I know im six months late but in case you see this i think this could be a very cool bit of information! What the college student was reffering to here was actually the private encryption keys that ICANN has associated with the "trust anchor" (the public encryption key for the entire internet). Essentially there is a harddrive locked away in an ICANN building that is only accessible with certain key cards that are locked in seven different physical boxes, requiring "seven keys". There is a really great video i watched about it a while back called "The seven people who can turn off the internet" by the channel named Half as Interesting that talks about it!

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.

to know internet you just have to learn how TCP/IP works, it's a simple protocol you can get around it in a couple days. but to understand the complete know-how of the infrastructure you need a semester or two with a lot reading of RFCs.
