How My Training As An Inventioneer Altered Ethernet
Unable to load video? Click here.
Everyone said it was impossible. Engineers laughed and called it ‘The Billings Folly’ — as a joke. Then the entire internet adopted it, and now the whole world uses it.
Dr. Roger Billings tells the inside story of how full duplex gigabit Ethernet was invented, rejected at IEEE standards meetings, and eventually became the global standard behind modern internet, streaming video, and AI.
Discover the inventions that made it possible — the concentrator, the equalizer circuit, and the balanced hybrid circuit — and hear what happened when Ron Crane, the father of Ethernet himself, stepped in to defend it.

Question: In a recent science live I heard Roger Billings mention investing in a science project of his choice this year, what does that mean?
Comment this live was awesome so far i can’t wait to see what else i learn.
hey class! 😀
i wonder if they can make anything that will let it send at the same time without there being any crazy things
How Do you undo the muffling
