Which of the following condition is encountered if two packets are transmitted over a medium at the same time?
Collision condition is encountered if two packets are transmitted over a medium at the same time.
collision. In a half duplex Ethernet network, a collision is the result of two devices on the same Ethernet network attempting to transmit data at exactly the same time. The network detects the "collision" of the two transmitted packets and discards them both. Collisions are a natural occurrence on Ethernets.
Specifically, collisions can either be elastic, meaning they conserve both momentum and kinetic energy, or inelastic, meaning they conserve momentum but not kinetic energy. An inelastic collision is sometimes also called a plastic collision.
CSMA/CD. Short for Carrier Sense Multiple Access/Collision Detection, CSMA/CD is a Media Access Control (MAC) protocol. It defines how network devices respond when two devices attempt to use a data channel simultaneously and encounter a data collision. ... This mode waits for the medium to be idle, then transmits data.
