Final answer:
CSMA/CD is the protocol that requires hosts to stop transmitting and then wait for a random interval after detecting a collision on the network.
Step-by-step explanation:
The protocol that requires a host to cease transmission for a random interval once a collision is detected on the wire is CSMA/CD (Carrier Sense Multiple Access with Collision Detection). CSMA/CD is used in networks to manage data transmission and to handle situations when two devices try to send packets simultaneously. When a collision occurs, each device stops sending data, waits for a random period of time before retransmitting, to minimize the chance of colliding again.
