The Collision Problem That Crippled Ethernet (And How We Solved It)
Ever wonder how computers actually talk to each other over a wire? In this episode of ScienceLive, we break it all down — starting with the earliest Ethernet networks running over coaxial cable, through the switch to Cat5 cabling, and into the fundamental building block of all network communication: the packet.
You’ll learn what packets are, how they carry your data across a network, and why early Ethernet had a serious flaw — data collisions that could bring an entire network to its knees. We explain why collisions happen and what they mean for the data you’re trying to send.
Then comes the part we’re most excited about: how my team and I discovered a solution to stop packet collisions entirely, leading to the invention of WideBand networking. In this episode we give you the teaser — next week, we’ll teach you exactly how it works.
This lesson is for anyone who wants to truly understand computer networking from the ground up — how Ethernet came about, how it works, and where it’s headed.

I thought it was interesting how police try to control traffic and how we use similar ways for the internet.
Amazing science live, see you next week!
R51s invention is pretty genius but not for some questions
I enjoyed this episode learning the importance and process to ethernet. Looking forward to the next episode.
Wow! There is a lot to learn on how we stay connected all around the world. Cool!
I’m so glad there are so many great inventors out there!
It is interesting to see how the cables were developed and improved upon.
That is wonderful you are going to review the inventions and potentially invest in them. Thank you for helping shape the future!
Interesting to hear about how much things have improved and the issues that used to come up.
The Ethernet was really interesting to here about.
Interesting history of the ethernet. And I like him saying that the greatest inventions are often hiding under your biggest problem.
Amazing inventions!
R-51 is the best
This episode was really great!
i love watching science live
Didn’t know much about ethernet, now I do.
It was interesting in learning the police trick they use to get traffic flowing and how you used this idea to help ethernet work better.
I love the internet and how it works.
An interesting episode!
