Collision Detection

Collision Detection is a MAC method of detecting simultaneous transmissions in a network. In a Enternet, each transmitting workstation will detect the collision and delay retransmission in order to avoid a repeat of the collision. Workstations can tell that a collision has taken place if they do not receive a response within a certain time frame or if no acknowledgment is received from the server. While transmitting, stations continue to listen for incoming signals (collisions) and emit a jamming signal to notify all other stations of the collision. Collision detection (CSMA/CD) is used in wired Ethernet LAN.
