The devices that were involved in the collision do not have priority to transmit data.
(JAM) When a collision occurs, each node that is transmitting will continue to transmit for a short time to ensure that all devices see the collision.
Half-duplex – uses CSMD/CD
-Walkie-talkies, CB Radios – only one person can talk at a time. Data can only flow in one direction at a time.
Full-duplex – no collisions because use different channels to send and receive. Must have a switch, NICs that support it.
