I’m still amazed that CSMA/CD works at all. We got hit with the Nimda virus in the early 2000s and our network utilization was over 50% and I’m like yup we’re going down. Once Ethernet gets bad it blows up pretty quick
It does and it doesn’t. Most wired ethernet isn’t on shared media, so it doesn’t need/use csma/cd… But wireless is based on ethernet and uses csma/cd (wifi) presumably

I wonder if we were still using hubs back then. We bought a bunch of Cabletron switches around that time
Wireless uses csma/CA, IIRC. It avoids collisions rather than detecting and responding.
