Collisions are particular to networks using a Carrier Sense Multiple Access/Collision Detection (CSMA/CD) protocol, such as traditional Ethernet. When devices on the same network segment transmit simultaneously, collisions occur, leading to a temporary network slowdown as the devices must retransmit their data. These are less common in modern switched and full-duplex networks where the switch architecture mostly eliminates the chance of collisions.
