When Collisions occur in Ethernet LAN
1. Jam Signal informs all devices that a collision occurred.
2. The collision invokes a random back-off algorithm
3. Each device on the Ethernet segment stops transmitting for a short time until its back-off timer expires
4. All hosts have equal priority to transmit after the timers have expired
This concept is key but the amount of questions in the exam are small, three at most. However, this isn't a hard concept to remember. So don't let those easy questions go to waste, get them right on the exam!
