I found these videos while looking for a way to prep for CompTIA exams. I stuck around for the SG-1 references.

I saw the names for half-duplex ethernet and immediately was taken to my teen years and the sci-fi channel with my dad. thank you for breaking down these concepts so well

I was trying to figure out why the marmalade was on the screen at 10:25 and then he said 'jam'

With CSMA/CD, how can a device transmit a jam signal if that Ethernet connection has already been locked up by the original collision? Wouldn't the jam signal itself collide over that connection?

You can listen while sending. So what happens is a device receives a transmission while they are sending out. They send a Jam signal and then start a random back off timer. Everyone receiving the Jam signal also starts their own random back off timer. That's my understanding of it. So half duplex can't send and receive, but it can listen and send.

In the N10-008 objectives, they mention CSMA/CD under 2.3. However in the acronyms list, they also mention CSMA/CA. I didn't see any mention of it in your videos but I know how strict you follow the objectives. I'll just study it in case it comes up

@@woodcrest4655 nah I don’t think so. messer even said in the vid that it’s not required but it’s useful to know basically that it contains the source/destination MAC addresses and the payload which has IP data

CSMA/CA is used in wireless networks for Collison Avoidance. Think of CSMA/CA for 802.11 (wifi). CSMA/CD is for 802.3 (ethernet).

I'm still a bit confused: how does a sender resolve the target's MAC address before sending the traffic? E.g. the "SGC server" is 2 hops away from Sam, how does Sam get its MAC?

Regarding CSMA/CD… is there a particular reason the wait value is random, instead of say procedural?

If you're trying to avoid everyone talking at the same time, you'd probably want to start by making sure everyone won't talk at the same time. :)
