The Collision Problem That Crippled Ethernet (And How We Solved It)
Unable to load video? Click here.
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.

Dr. Billings,
My family started watching science live because I had to leave my school and my mom couldn’t afford the full tuition. At first I wasn’t so excited. But it has become a family event. My big brothers and adults cousins have been coming over to watch it with me and mom and talk about it together. It been really fun and I appreciate you so much for the help.
Hello from Illinois <3
how did he come up with this circuit
I am excited for live!
Hello from Mississippi
hey from ms
I really liked the protégés part about How Ethernet works
hi from louisiana
hi from ms
Happy to be here
hello from Texas
Hi from TX!!
Hello from California!!!!
here from columbus ga
Happy Wednesday!
hi y’all so excited to be in class today
Good evening from Florida!
Learning about Ethernet is making me look forward for next weeks live!! Can’t wait to learn more in depth.
Hi from Texas! Excited for tonight!
How does the Ethernet work? Like is it just internet sent through a cable or is it entirely different??
hi from tennessee
Im excited for tonight! Thank you for these videos, watching from Kentucky
Loved it!!!
What actually happens to the data packets during an Ethernet collision, and why was it considered to cripple the network?

Hi from sc
I wonder if it could be possible to use the vampire tip cable to connect an old computer with a new one. Would take a lot of engineering, though.
Hi from Colorado
Hello from FL
Hello science live! I’ve heard the word “Ethernet” before but never knew what it was. Guess I’ll learn about it!
What would happen if you got one of those cables mixed up
hi from Texas
How do you stop collison packets ?
Hello from NY!! Have a good day/night!
i always love watching these videos its really amazing
This episode was great!

Hi from NC, very cool to learn about Ethernet tonight.
Whoo! Dr. Tobias is my favorite!!
Ethernet is a great invention and very underrated nowadays.
Hi everyone. I’m looking forward to today’s class!
Comment Hello from Charleston, SC!
The Proteges are the best part of my day!! They always bring a smile to my face:)
How many kinds of Ethernet cable is there?
heyy from hawaii
Hi from Memphis! Great live!
Hi from MS
What is the maximum speed that ethernet supports?
So cool!
Hi from Kentucky!
I’m so ready for this live
How much did it cost to make the ethernet?
