switch interfaces

Question 1

CSMA/CD

Answer 1

Carrier sense multiple access with collision detection - Used in half-duplex to mitigate collisions

1. listens for others to not send and begins sending
2. if collision happens, all stop and wait random interval before sending agian

Question 2

Autonegotiation

Answer 2

Devices try to figure out which speed or duplex to use with the other connected devices. Fastest speed that both support will be chosen.

Question 3

What happens if other device does not have autonegotiation?

Answer 3

device will try to detect speed and half-duplex will be used if speed is at 10/100 mbps
