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.
