In this video, learn how coax-based Ethernet transformed into Ethernet of unshielded twisted pair.
- Here's the ethernet segment from the previous episode.…Now, these old ethernets worked great back in the day…but they had one really ugly Achilles heel.…And that was this.…If the segment itself broke at any location,…the entire network would drop.…And that was a problem with these old versions of ethernet.…So, it was something we put up with…until a little tiny company called IBM came along…and they came up with a competitor…to ethernet called Token Ring.…
So we're talking late 1980s here.…Token Ring, when it came out, didn't use a bus.…What they did, is they basically had a box,…and you would plug all your different computers…into this box.…It was called an MSAU, multistation access unit.…Whatever, but they changed the idea.…And with Token Ring, if any one of the computers broke,…it didn't take down the entire network.…Now Token Ring was great stuff, but it had two problems.…The first problem was, well it was proprietary.…
It came from IBM.…And you couldn't make your own Token Ring stuff.…The other big problem with Token Ring,…
