It signals to the network that its data was damaged in a collision, waits a brief period of time before checking the network for activity, and then retransmits the data.

CSMA/CD: Carrier Sense Multiple Access / Collision Detection.
Csma/cd
*** In CSMA/CD it detects that a collision take place and resend the frame that was send. On a wirless network losing bandwidth along with time to detect that a collision took place was not acceptable , so CSMA/CA was utilized. ** CSMA/CD can achieve above 70% efficiency under heavy loads compared to CSMA/CA that can only achieve up to 30% efficiency under heavy loads. CSMA/CA network: A network in which the medium access control protocol requires carrier sense and where a station always starts transmission by sending a jam signal; if there is no collision with jam signals from other stations, it begins sending data; otherwise, it stops transmission and then tries again later. CSMA/CD network: A bus network in which the medium access control protocol requires carrier sense and in which exception conditions caused by collision are resolved by retransmission
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance)
No, Ethernet does not use Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). Instead, Ethernet employs Carrier Sense Multiple Access with Collision Detection (CSMA/CD). In CSMA/CD, devices listen to the network before transmitting and can detect collisions that occur, allowing them to retransmit after a random delay. CSMA/CA is primarily used in wireless networks, such as Wi-Fi, to help prevent collisions from occurring in the first place.
The acronym CSMA CD stands for Carrier Sense Multiple Access with Collision Detection. CSMA CD is a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously.
Carrier Sense Multiple Access (CSMA) is a network protocol used to manage access to a shared communication medium. It operates by having devices first listen to the channel to determine if it is free (carrier sensing) before attempting to transmit data. If the channel is busy, the device will wait until it becomes free; if it’s clear, the device sends its data. To prevent collisions, CSMA may use techniques like CSMA/CD (Carrier Sense Multiple Access with Collision Detection) or CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance).
WAPs use CSMA/CA - Carrier Sense Multiple Access with Collision Avoidance.
it prevents the collision between the data that is sended by the network cards over ethernet networks
The vulnerable time period in Carrier Sense Multiple Access (CSMA) occurs during the time it takes for a node to detect a collision after it has begun transmitting. This period includes the time it takes for the signal to propagate through the network and for the collision to be detected by other nodes. The length of this vulnerable period can lead to increased likelihood of collisions, especially in high-traffic environments, as other nodes may not sense the channel is busy until it's too late. In CSMA/CD (Collision Detection), this is particularly critical, as it can affect overall network efficiency and performance.
