Sponsored by PCBWay: Travel back to the roots of Ethernet as we explore the basics of 10BASE2, the technology that once powered local networks. In this video, we'll break down the fundamentals of the OSI model with a focus on layers 1 and 2 and shedding light on the vintage hardware that made it all possible: Get up close with network cards, RG-58 coaxial cabling, and the critical function of repeaters. We'll also take brief detours to compare 10BASE2 with its predecessors 10BASE-5, and its successor 10BASE-T. 00:00 Intro 00:38 Into 10BASE2 basics 02:16 10BASE2 origins 03:17 The most simplistic 10BASE2 network 05:28 Extending a 10BASE2 network 06:05 10BASE2: Bus Topology 07:06 Extending 10BASE2 beyond segments 07:51 Repeaters and Hub/Repeaters 10:12 Into Layer2, NICs and MAC addresses 12:00 Why 10BASE2 is a broadcast-type medium 13:06 CSMA/CD explained 14:01 The thing about multi-connector NICs 17:24 Attaching 10BASE5/AUI NICs to a 10BASE2 network 17:20 A very brief look into 10BASE5 17:46 10BASE2/10BASE-T media converters 18:24 Conclusion 19:01 Next on TPC / Outro Links: (telecommunications) Windows for Warehouses: Visit also THE PHINTAGE COLLECTOR website at for insights into my retro computer collection.
