Ethernet is a data transmission method where each host on the network share a link’s bandwidth equally. Ethernet utilizes Carrier Sense Multiple Access with Collision Detection (CSMA/CD), meaning that before a host on an Ethernet network will transmit, it listens for a signal on the Ethernet wire first to see if another host is currently transmitting. If the wire is silent, the host will begin transmitting.
If another host attempts to transmit while the first host is still transmitting, the sending host will transmit a jam signal informing all hosts on the wire to stop transmitting. The nodes that receive that jam signal will not attempt to transmit for a certain period of time.
